New Reinforced Concrete Building Design
The program runs its analyses in line with the conditions prescribed by the 2018 earthquake code (TBDY2018) for reinforced concrete buildings. Depending on user choice, seismic forces can be calculated with the equivalent earthquake load method, the shear-frame modal method, or modal analysis with finite element matrices — with rigid, flexible or no diaphragm. Buildings with rigid basements can also be solved. Shear walls can be modelled with shell or frame finite elements. Load transfer from slabs to beams can be done with shell finite elements (quadrilateral or triangular, regular or irregular Delaunay mesh) or, if preferred, with the classical method. Slab internal forces can be taken from shell finite element results or calculated with TS-500 approximate methods. The program's finite element and modal analysis results agree closely with SAP2000. For the verification calculation, please click here.
Foundations can be solved as continuous footings, beam-supported rafts or beamless rafts. Soil–structure interactive analysis is performed. Polygon columns of any geometry and reinforcement layout are analysed by biaxial iterative analysis or by two uniaxial iterative analyses, depending on user choice, producing interaction diagrams and all checks. The reinforcement layout of polygon columns can be determined automatically by the program or by the user.
Rectangular columns can be solved with a biaxial iterative analytical solution, two uniaxial solutions, the Çakıroğlu–Özer method or the polygon section algorithm.
Beam reinforcement is calculated for the double-reinforced case, and slab-induced torsion is calculated with high accuracy when slabs contribute to system stiffness.
The program needs no additional software for analysis or drawings. If desired, the building model can be exported to SAP2000 and analysed there according to the Turkish Earthquake Code or any other code; StatiCAD then automatically produces summary reports interpreted from the SAP2000 design results together with beam and column reinforcement drawings. Alternatively, bi-directional automatic data transfer with SAP2000 can be used for model verification and testing.
Calculation reports are prepared in great detail and in a clear, verifiable form.
Reinforced concrete project drawings are produced side by side with a single click, saving you the labour of assembling sheets.

 

New Masonry Building Design
Optionally, the program automatically applies all formulas prescribed for masonry buildings by the 2018 earthquake code and the 2019 risky building regulation.
TBDY 2018 sets out masonry analysis and design in such detail that calculating by hand is practically no longer feasible. With its advanced interface and analysis options, StatiCAD aims to solve your project as accurately as possible. Backed by years of experience, a mature program infrastructure and more than 1,000 users who trust us, it fills an important gap in this field. Its strengths include the equivalent strut method, the frame finite element method, modal analysis, equivalent earthquake load analysis, inclusion of slabs in system stiffness with shell finite elements, load transfer from slabs to walls and other elements with shell finite elements, confined masonry analysis (taking the contribution of vertical tie-columns to wall strength and/or system stiffness into account), reinforced masonry wall analysis (assigning vertical and horizontal reinforcement inside brick walls, as defined in the 2018 earthquake code, for walls that would otherwise fail) and reinforced or unreinforced wall checks that take moment effects into account. In masonry structures, wall axes, end nodes, thicknesses, eccentricities and materials may change from storey to storey. StatiCAD transfers loads between storeys without axis or node dependency, so the zero-compression-stress error seen in other programs is avoided. The first version of the program was released in 2010 and development in the masonry field has continued without interruption.
The program's greatest advantage over spreadsheet calculations is that it transfers vertical loads between structural elements using the shell finite element method or the yield-line method. Spreadsheets usually divide the storey weight by wall lengths or areas to obtain average values, whereas real load distributions vary widely with room and building geometry. Because the shear capacity of a wall depends on the vertical load acting on it, walls carrying little vertical load have much lower shear capacity. A wall or building that passes in a spreadsheet may turn out to be insufficient once loads are distributed as they should be. If there is an error in vertical load transfer or modelling, the program reports the error ratio after analysis and automatically corrects most modelling errors that may occur during analysis. The only axis dependency in the program is between the ground floor and the foundations; there is no axis dependency between storeys, so node points need not coincide between storeys for load transfer and static calculations. This gives the program great flexibility and allows almost any masonry structure to be modelled.
Internally, the program can use the finite element method or the classical method. You can expect a one-to-one match between the program's calculation and a detailed, correctly performed hand calculation.
All calculations prescribed by the codes for masonry structures are performed automatically by the program.

 

New Timber Building Design
Timber buildings can be calculated in accordance with the 2018 earthquake code and the Principles for the Design, Calculation and Construction of Timber Buildings (ABTHYE), published in Official Gazette No. 32499 on 24/03/2024.
Timber shear walls (light-frame wall systems) are entered with sheathing on one side or both sides. End studs, intermediate studs, top plates, bottom plates and blocking are created. Timber slabs are entered as slab sheathing, joists and horizontal blocking beams. Independent timber beams and timber columns can be entered, and wind and snow loads are defined.
In analysis, the program automatically defines the 87 load combinations required by the code for timber buildings, including vertical, earthquake and snow loads, and automatically calculates seismic loads and element internal forces. For timber shear walls it calculates the shear capacity according to TBDY2018 and states the sufficiency in the reports. Timber members are checked according to the strength-based design section of ABTHYE — tension parallel to grain, bending limit state, lateral buckling limit state, compression parallel to grain, shear parallel to grain, rolling shear, torsion, combined effects (bending moment and axial force) and compression perpendicular to grain — taking moisture and size factors into account. Timber elements can be defined within a timber structural system as well as within masonry or reinforced concrete systems. If desired, cross-section and deflection checks of beams can also be performed according to TS 647.
Nailed, screwed, bolted, dowelled and plate connections between timber members can be calculated according to Section 4.11 of the 2024 Timber Structures Specification (Eurocode 5); the connection geometry can be inspected in 3D and transferred to the technical drawing

 

Performance Analysis and Strengthening of Existing Masonry Buildings
In the program (Professional and Ultimate versions), strengthening calculations and drawings for masonry buildings can be prepared using steel mesh and shotcrete, fibre-reinforced polymer wrapping, or the addition of new vertical tie-columns, shear walls or walls. StatiCAD performs all operations without any additional software. As options, it also offers SAP2000-automated finite element analysis with shell elements and response spectrum analysis.

Internally, the program can use the finite element method or the classical method. You can expect a one-to-one match between the program's calculation and a detailed, correctly performed hand calculation. If desired, the project can be exported to SAP2000; after the analysis, the results are retrieved automatically and the design is completed according to the SAP2000 finite element results.
All calculations prescribed by the codes for masonry structures are performed automatically by the program.

 

Historic/Traditional Structures and Structures with Curved Surfaces
Triangular or quadrilateral slabs/rafts with curved or circular edge(s) or surfaces can be modelled. Domes, vaults, elliptical domes, helical stairs, Turkish triangles, circular slabs, curved slabs and general 3D curved slabs (convex or concave) can be modelled. Arches can be created by rotating a concave curved slab around the X or Y axis.
After a quadrilateral slab is entered, the program creates node points (finite element joints) at the slab corners and at the midpoints of the slab edges; these points also serve as control points for curving the slab system. When the mid-edge nodes are moved away from the average coordinate of the slab corners, the slab is curved so as to follow the mid-edge points. Depending on user choice, the slab surface can be meshed into triangular or quadrilateral shell finite elements. After analysis, node displacements (UX, UY, UZ, Rx, Ry, Rz, U-total) are shown as contour lines in the 3D view for the selected load combination. For shell elements, the internal forces F11, F22, F12, M11, M22, M12 calculated at the element centre and the stresses Sigma11, Sigma22, Sigma12, Sigma Von Mises, Sigma Max and Sigma Min at the lower or upper surface are displayed per storey in the 2D viewer, colour-coded by stress value. Loads from curved slabs are transferred automatically to other structural elements, and the building can be solved with a rigid diaphragm or with a flexible diaphragm that accounts for slab stiffness. Curved slabs can be defined in reinforced concrete, masonry and timber building systems


Masonry Wall Out-of-Plane and Dome Checks
Overturning, vertical and horizontal bending, out-of-plane shear and slenderness of masonry walls under earthquake effects perpendicular to their surface can be checked according to TS EN 1996-1-1 (Eurocode 6) Clause 6.3 and Annex E; the demand is determined with the TBDY 2018 Chapter 6 approach, and support conditions can be defined wall by wall. Domes modelled with the dome tool are recognised automatically from their geometry; a closed-form solution based on membrane theory and Heyman's cracked dome model is compared with the finite element shell results, meridional compression, hoop tension, out-of-plane shear and geometric safety are checked, and the springing thrust is transferred to the out-of-plane check of the walls supporting the dome. These checks are offered as an additional adequacy control, especially for existing and historic masonry structures; results are given with formulas and substituted values on separate report pages.

 

Performance Analysis of Existing Reinforced Concrete Buildings (TBDY 2018 Chapter 15)
The seismic performance of existing reinforced concrete buildings can be determined according to TBDY 2018 Chapter 15 both with the linear method and with nonlinear pushover analysis. The linear method uses element demand/capacity ratios, knowledge level factors, strain and damage limits. In pushover analysis, column, beam and shear wall sections are defined with a fibre section model (Mander model for confined and unconfined concrete), and moment–curvature relationships, biaxial plastic hinges and an event-to-event incremental solution are used. Single-mode pushover analysis (Annex 5B) is run in eight directions (±X ±0.3Y); P-Δ effects, a hardening hinge model and a variable load pattern (TBDY 5.6.5) can optionally be included. For buildings where the mass participation of the dominant mode is insufficient or torsional irregularity exists, multi-mode pushover analysis (TBDY 5.6.6, CQC combination) and the IRSA incremental modal combination method can be used. The target displacement, performance point, element and storey damage zones and the building performance level (Limited Damage / Controlled Damage / Collapse Prevention) are determined and reported automatically; secondary beams are identified automatically. The pushover engine has been verified against SAP2000 and OpenSees; if desired, the analysis can also be run comparatively with SAP2000. (Available in the Ultimate, Professional and Betonarme versions.)

 

Strengthening of Existing Reinforced Concrete Buildings (TBDY 2018 15.10, Annex 15B and Annex 15C)
The strengthening methods of TBDY 2018 Section 15.10 have been added to the performance analysis chain. Strengthening is defined as a property of the element on the Strengthening tab of the element property windows and is stored in the same project file; with a single option the building is calculated in its state before or after strengthening. FRP wrapping of columns, beams and shear wall boundary regions (Annex 15B: confined concrete model, damage limits, shear contribution and confinement check for insufficient lap splice length), reinforced concrete and steel jacketing, column section enlargement (concrete jacket with longitudinal reinforcement and ties), external stirrups on beams, cast-in-place reinforced concrete strengthening walls (with a frame anchorage check) and strengthening of infill walls with steel-mesh reinforced plaster or diagonal FRP strips (Annex 15C, equivalent diagonal strut model) can be calculated. The building performance level, criterion percentages, strengthened elements and changes in damage zones before and after strengthening are shown side by side in the report; violations of strengthening rules are reported in the project check list. (Available in the Ultimate, Professional and Betonarme versions.)

 

Precast Reinforced Concrete Building Design
Precast industrial buildings and precast concrete buildings can be solved with the program's own finite element analysis. Variable-section (nonprismatic) roof and truss girders are modelled without splitting the element, with stiffness integrated along the section; Precast I (Bulb Tee), Precast U, Precast Box, trapezoidal and box sections are defined with parametric templates and saved to the section library. Pinned connections and rigid end zones, representation of the roof diaphragm as a rigid diaphragm or with TBDY Annex 8B equivalent braces, facade panel and crane masses (weightless additional seismic mass), overhead crane loads and different R and D factors for the upper and lower parts of the building (TBDY 4.3.6) are supported. TBDY Chapter 8 connection design (pinned connection, moment connection that is cast in place at the top and welded at the bottom, purlin and gutter connections) is performed with demands taken directly from the analysis; reinforcement design of polygon and variable-section beams, facade panel seismic load (TBDY Chapter 6) and sliding at the foundation (TBDY 16.8.4) are reported. The calculations have been verified against numerical examples from the reference book and independent finite element comparisons with SAP2000. (Available in the Ultimate version.)

 

Steel Member Design in Buildings (ÇYTHYE)
Steel beams and columns in buildings can be designed according to TBDY 2018 and the Turkish Steel Structures Design, Calculation and Construction Principles (ÇYTHYE) using the load and resistance factor design (LRFD) approach. Sections are assigned to beams and columns from a fabricated profile library of 1008 sections (IPE, IPN, HEA/HEB/HEM, HD/HL/HP, UPN, UPE, angles, T, RHS/SHS hollow sections, CHS pipes), and the steel grade (S235, S275, S355, etc.) is selected through the section. Beams are checked for flexure (yielding, elastic and inelastic lateral-torsional buckling), shear, combined effects and deflection; columns are checked for flexural and torsional buckling, slender section classification and combined effects with biaxial bending. Internal forces are taken from the program's finite element solution; reports show the governing limit state and the load combination behind each demand, and profiles are drawn in the 3D view with their true section geometry. (Available in the Ultimate and Hybrid versions.)

 

Light Gauge Steel Building Design (HCBTİE)
Cold-formed (light gauge) steel panel buildings can be designed within the scope of TBDY 2018 Chapter 10 and the Turkish Principles for the Design of Light Gauge Steel Buildings (HCBTİE). The panel sheathing shear capacity is calculated according to TBDY 2018; panel studs and light gauge steel beams and columns are checked with the Effective Width Method (EWM), including local, distortional and flexural–torsional buckling. Distortional buckling can be calculated with the HCBTİE general method or the finite strip method; rotational restraint from sheathing, edge stiffener adequacy and cross-section conditions are checked. Out-of-plane wind bending and deflection checks for exterior wall studs, choice of LRFD or ASD design method, HCBTİE load combinations, panel structural conditions (Chapter 6), panel anchorage and connection design (Chapter 8), the D factor for end studs, the seismic allowance for gypsum-sheathed panels and design of foundations for internal forces amplified by D are provided. 527 sections from the Hekim profile catalogue (C, Z, U, C+, Sigma, Sigma+) are available in the built-in library. The calculation engine has been verified against code equations, hand calculations and finite strip solutions. (Available in the Ultimate version.)

 

AI Assistant and BIM/IFC
You can use StatiCAD with an AI assistant that you direct in natural language: create the model by typing or by speaking into the microphone, and get help with drawing elements such as walls, columns, beams, slabs, axes, doors, windows, reinforcement and foundations, with storey operations, analysis and reporting. The assistant can also evaluate files and images, works in several languages (it replies in the interface language) and, for advanced use, enables terminal automation with tools such as Claude Code/Codex. The AI is positioned as an assistant, on the principle that the generated model and results are reviewed by the responsible engineer .
For building information modelling (BIM) workflows, the program imports and exports using the IFC (IFC2x3, Coordination View 2.0) standard. You can export your project to IFC in one step and share it with tools such as Revit, ArchiCAD, Tekla, Allplan or SAP2000, and import physical IFC models and SAP2000 structural analysis models from these tools into StatiCAD (frame members become columns/beams; area members become walls, slabs and shell elements). Unit (metre/centimetre) and character differences are handled automatically in the background. The AI and BIM/IFC features are available in the Hybrid and Ultimate versions (in the demo version IFC import is enabled and export is disabled).
