ProtaStructure 2026: Feature Overview

ProtaStructure Suite 2026 is a comprehensive structural engineering software package that includes ProtaStructure (core modeling and analysis), ProtaDetails (detailing), and ProtaSteel (steel design). Built on over 40 years of expertise, it offers advanced tools for seismic design, BIM integration, and automated detailing for reinforced concrete (RC) and steel structures. Below are the key features.

1. Advanced Modeling Tools

  • Comprehensive Modeling: Supports modeling of beams, columns, slabs, walls, and complex elements like cruciform columns and subbasement walls.
  • New Reinforced Concrete Stair Module: Enables interactive modeling, finite element (FE)-based analysis, automatic meshing, and detailed drawings for RC stairs.
  • Steel Base Plate Module: Provides precise modeling and anchorage design compliant with international codes (e.g., ACI318, AISC360, EC2, EC3, Turkish codes).
  • Foundation Pedestals and Subbasement Elements: Simplifies modeling and analysis of semi-basement walls, beams, slabs, and foundation pedestals.
  1. Seismic Design Enhancements
  • Advanced Seismic Analysis: Includes automated seismic load calculations, enhanced diaphragm options, and irregularity assessments per codes like Eurocode 8, US, and Turkish standards.
  • Nonlinear Analysis: Supports nonlinear base isolators, multi-mode pushover, time history, and P-Delta analysis for earthquake-resistant designs.
  • Customizable Spectra: Offers customizable seismic spectra and modal vertical seismic analysis for precise code compliance.
  1. BIM Integration and Interoperability
  • Seamless Integration: Bi-directional links with Revit, Tekla Structures, ArchiCAD, and IdeaStatica via IFC4, DXF, and SAF formats.
  • Enhanced IFC4 Support: Improves data exchange and compliance with standards like Singapore’s BCA CoreNetX for BIM submissions.
  • DXF Architectural Integration: Enables accurate load placement and transparent image export for high-resolution model visuals.
  1. Automated Detailing and Documentation
  • Automatic Drawings: Generates structural concrete and steel detail drawings with a single click, including dynamic quantity tables and material lists.
  • Enhanced Post-Processing: Provides support reactions, usage ratios, and rebar quantity tables.
  • Detailing Features: Supports Eurocode 8 shear wall envelopes, new slab reinforcement patterns, and curved beam/truss connection macros.
  1. Analysis and Design Capabilities
  • Finite Element Analysis: Offers static, dynamic, nonlinear static, construction stage, and advanced seismic analyses.
  • Crack Width and Punching Shear: Enhanced controls for crack width (EC2, ACI318, IS456) and punching shear checks for flat slabs and raft foundations.
  • Flexible Analysis: Includes adjustable eccentricity, safety factors, and refined mesh modeling for accuracy.
  1. User Experience and Productivity
  • Customizable Interface: Features customizable shortcuts and a modernized interface for tailored workflows.
  • Automated Load Cases: Supports dynamic soil and snow drift load calculations, reducing manual input.
  • Performance Improvements: Faster modeling, analysis, and visualization compared to ProtaStructure 2025.
  1. Applications
  • Used globally in 95+ countries for high-rise buildings, seismic design, and steel/composite structures.
