The complete integrated environment for structural BIM modeling, multi-material analysis, code-compliant design, and intelligent drawing production.
— all in a single suite.
Designed by Engineers, for Engineers
Five capabilities.
One integrated workflow.
ProtaStructure unifies every stage of structural design — from initial model to code-compliant output — inside a single BIM environment. No data transfers, no tool-switching, no version drift.
Achieve Faster Design Times
Automate load combinations, tributary areas, and drawing output. Complete full-project runs in minutes, not days.
Manage Changes Easily
Architectural revisions propagate through the structural model automatically — no re-entry, no version conflicts.
Produce Intelligent Drawings
Fully-annotated reinforcement and framing drawings generated directly from the BIM model, with automatic rebar scheduling.
Deliver Design Documentation
Structured calculation reports, code compliance checks, and submission packages generated at any project stage.
International Design & Seismic Codes
Design to 50+ global standards — Eurocode, ACI, AISC, TBEC, IS, AS, and regional seismic provisions — in one environment.
BIM-First Structural Engineering
Explore BIM Solutions
Built for Structural Teams
ProtaStructure gives structural engineers a single integrated environment — from initial model geometry to final code-compliant design and documentation. Every workflow step stays inside the same BIM database, eliminating the data loss that comes from using disconnected tools.
Define structural elements directly inside the BIM environment. Geometry, properties, and material assignments are live data — not imported geometry.
Run linear, P-Delta, response spectrum, and nonlinear analyses. Design concrete, steel, and timber members in the same session.
Structural drawings, reinforcement schedules, and calculation reports are generated directly from the model — always coordinated with the current design state.

Member Design
Comprehensive Member Design and Checks
Beyond analysis, ProtaStructure offers detailed design checks to ensure code compliance to local and international design codes. This includes the ability to perform long-term deflection checks for RC beams according to Eurocode 2, which automatically account for the time-dependent material properties of creep and shrinkage.
Load Editor
Powerful Interactive Load Editor
ProtaStructure streamlines structural design with its automated and precise load analysis, enhancing efficiency and accuracy.
In addition to automatically calculated loads, our interactive load editor allows you to visualize and apply any additional loads of your choice including soil pressure, point, line and area loads in any orientation. You can even import point loads from Excel for comprehensive batch case management.
ProtaStructure greatly simplifies the calculation and application of environmental loads such as snow, rain, and roof live loads.
Offers tools for evaluating soil thrust against structures, considering water table and soil profiles for both static and dynamic analysis.
Load Calculations
Automated Load Calculations
ProtaStructure effortlessly breaks down the vertical loads for various floor systems using advanced methods like Yield Lines and Finite Element Decomposition, with support for diverse geometry and loading scenarios, featuring color-coded visual checks for load assessments, finishes, and structural dimensions.
ProtaStructure automates Seismic, Wind and Notional Load calculations in compliance with major international codes such as EN 1991-4, EN 1998-1, ASCE07, BS6399-2, and more, alongside snow load assessments per EN1991-1-3 and TS498.
You can also leverage the automated generation of soil dynamic load cases and snow drift load cases, which are seamlessly integrated into the analysis and combination process.
These powerful load automations, coupled with fully automated load combination generation saves you hours of valuable project time.
BIM Collaboration
Leading Structural BIM Collaboration
Developed with BIM in mind, seamlessly communicate and refine models with other leading BIM systems, including Autodesk Revit, Tekla Structures, ArchiCAD, AllPlan, IdeaStatica and latest data formats, including IFC, 2D/3D DXF, and SAF. The powerful link with IdeaStatica allows you to communicate your steel connection geometry and internal forces for advanced connection analysis.
Design Modules
Powerful Integrated Design Modules
ProtaStructure also includes fully integrated modules to dramatically increase your productivity:
Interactive RC Staircase Module: We are thrilled to present our RC stairs module. This innovative feature allows you to interactively model RC stairs from a library of common types, seamlessly integrating them into the building model for a complete FE analysis. The design of flights and landings is then automated, complete with detailed reports and drawings.
Steel Base Plate Module: A comprehensive macro allows you to insert, model, and design steel base plates directly within ProtaStructure. This powerful tool streamlines the design process for base plates and anchorage according to ACI318, AISC360, Eurocodes, and Turkish codes, saving you hours of work.
BIM Modeling
True Structural BIM Modeling
Use dynamic input to rapidly create Concrete beam, columns, slabs, foundations and shearwalls and custom shaped corewalls and columns. Define openings, drops and physical set out to exactly define your project.
Use real structural Steel and Composite elements including truss, purlin, brace, girt, sag rods with flexible parametric macros. Specify your splice locations on steel columns, beams and trusses.
These capabilities are extended with the ability to model and design subbasement walls at the foundation level, create complex doubly symmetric cruciform columns, and seamlessly insert and design concrete foundation pedestals under steel columns.
Build one model! ProtaStructure enables you to model complex or straightforward concrete and steel buildings quickly and easily.

Performance Assessment and Retrofit
ProtaStructure provides a unique workflow for the performance assessment and retrofitting of buildings according to ASCE/SEI 41-17, backed by nonlinear single-mode pushover, multi-mode pushover, and nonlinear time-history analyses, with a fully detailed member-by-member assessment report. In addition to ASCE 41, this entire arsenal of powerful features is now fully compatible with Eurocode 8-Part 3 (EN 1998-3:2005) procedures, including nonlinear analyses and the q-factor approach. This allows engineers to perform comprehensive building assessments and retrofitting design against Eurocode 8 requirements.
Column, beam and wall sections can be modelled with fiber elements using distributed plasticity and analyzed with state-of-the-art techniques to derive Moment-Curvature relationships.
Seismic isolators can be placed at any point in the structure for various isolation scenarios. Nonlinear isolator characteristics can be factored into time-history analysis. Design outputs include storey drifts, accelerations, internal forces, and isolator displacements.
Take advantage of new non-linear static and multi-mode pushover and time history analysis together with performance-based design, assessment, and retrofitting of your buildings.
Cracked and uncracked section properties can be simultaneously used in the same analysis for different load cases. Code modification defaults can be automatically applied to section properties.
