Advanced 3D Finite Element Analysis
Utilize frame and shell finite elements, rigid zones, detailed diaphragm modeling, staged construction, and diverse analysis approaches for simple and complex projects.
Fast Project Delivery
Fast project delivery with fully integrated Concrete, Steel and Composite Slab design from one central structural BIM model.
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.
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.
Leading Structural BIM Collaboration
Developed with BIM in mind, seamlessly communicate and refine models with other leading BIM systems, including Autodesk Revit, TeklaStructures, 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.
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.
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.
Seismic Analysis and Design
ProtaStructure provides structural engineers with comprehensive tools to structural design and structural detail buildings quickly and economically to meet rigorous earthquake standards.
Advanced Seismic Analysis Tools
ProtaStructure has smart features for seismic modeling and analysis including EQS and RSA analyses, rigid and flexible diaphragm modeling, cracked sections, storey meshing, basement two-stage analysis and more. For projects requiring a site-specific survey, it also allows engineers to import multiple user-defined acceleration spectra and assign different spectrum curves in the X, Y, and Z directions for ultimate flexibility.
Global Seismic Checks
ProtaStructure performs a series of post-analysis checks including irregularities, strong column-weak beam, joint shear, non-structural member forces, wall-frame interactions, diaphragm checks and more. Support for Eurocode 8 is also comprehensive, with automated checks for torsional irregularity using the Torsional Radius method, dual system wall-frame interaction, and the application of design moment and shear envelopes for shear walls, including tension shift calculations.
Global Seismic Code Support
ProtaStructure supports an extensive array of seismic codes, including IBC, UBC, EC8, and more, ensuring designs meet international standards.
Ductile Design and Detailing
ProtaStructure automates the design of structural members to meet ductility requirements, such as confinement of critical sections, automatic layout of wall end zones, capacity shear design, ductile rebar curtailment and much more.
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 (ΕΝ 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.
Nonlinear Isolators
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.
Retrofitting & Performance Assessment
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.
Nonlinear Fiber Analysis of Sections
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.
Cracked and Uncracked Sections in One Analysis Run
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.
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.
International Codes & Standards
ProtaStructure is equipped to accommodate a wide variety of International Design Codes, such as those from the US and Europe, as well as localized standards tailored to meet the specific design and detailing preferences of users worldwide.
Support is also included for Brazilian Codes (NBR-8681 for loading and NBR-8800 for steel design) and a powerful Nationally Determined Parameters (NDP) Editor to seamlessly customize Eurocode parameters to align with national standards.
