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
Steel Detailing &
Automated Connection Design
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.

Connection Macros
Extensive Library of Connection Macros
With ProtaSteel, an extensive library of connections is at your disposal for your structural steel projects. ProtaSteel extends this library further by introducing new connection macros such as Angle Cleat Connection, Bolted End Plate Splice Connection, Base Plate for Hollow Sections, Haunch Connection for Continuous Beams.
Detailed Reports
Steel Connection Design and Detailed Reports
ProtaSteel supports connection design with comprehensive check reports to EC3, AISC (LRFD and ASD) and BS5950 with full code clause referencing including; bracing and truss connections, splice connections, and more.
Modeling Macros
Macros that Boost Modeling Productivity
In addition to connection macros, ProtaSteel offers a vast range of macros that will boost your productivity during modeling. Notch, Cut, Fit, Adjust, Weld, Bolt, Stiffeners, Batten Plates, Web Openings with Stiffeners, Automated Stair Treads, Chequered Plate, Gratings, Castellated Beams, Wind Column Connections, Beam to Beam Fixed Connections are among the powerful tools.
IntelliConnect
Revolutionary IntelliConnect for Fully Automating Connection Design
Revolutionary IntelliConnect® for fully automated steel connection design with a single click. IntelliConnect automatically assesses joints to your preferences, then batch creates and designs all your steel connections.
Custom Connections
User-Defined Steel Connections
Easily create your own user-defined connections using general detailing tools such as plates, bolts, welds, cuts, fillet and chamfers. Save these connections as a macro in the library to reuse them at similar joints, adding flexibility and efficiency to your designs.
Steel Detailing
Automate and Refine Your Steel Detailing
Open ProtaStructure models directly in ProtaSteel to start your detailing process. Easily navigate the entire model in 3D or work with model components of your choice. Choose and automatically design to your chosen code a broad range of bolted and welded connections. Adjust elements, add ancillary steel work and create unique connections using intuitive commands to suit your project requirements.
Shop Drawings
Clear and Concise Steel Detail Drawings
ProtaSteel will perform automated clash checks, model audit, part & assembly numbering seamlessly and flexibly. You can then create your general arrangement and part & assembly drawings using the central 3D model, including elevations, plans, sections and connections. You can use flexible annotations and title blocks to suit your drawing preferences. Save hundreds of hours by automatically producing shop details and producing CNC data for all steelwork fabrication.
BIM Interoperability
Save Time, Automate Details, Enhance Communication
Plot directly from ProtaSteel or publish DWG drawing output directly to ProtaDetails or your preferred CAD system including AutoCAD, Microstation and Bricscad. Seamlessly communicate the entire model with other leading BIM systems including Revit, Tekla Structures and IdeaStatica.
