Built for structural engineers

Multi-Material Structural Design in One Unified 3D Model

GSE™ General Structural Engineering is a 3D structural analysis and design program for buildings and structures in steel, cold-formed steel, wood, CLT, reinforced concrete and aluminum, including concrete slabs and foundations.

Model every material in a single model and analyze it with static, P-Delta, nonlinear, buckling, seismic and dynamic time-history analysis, with animated results and interactive result tables.

Members are designed to US and Canadian standards, from AISC 360 and CSA S16 to NDS, CSA O86, ACI 318, CSA A23.3, AA ADM and CSA S157, with redesign optimization, automated load combinations, slab generators and editable executive reports.

Engineered for productivity

Why Structural Engineers Choose GSE™

One program for every material, from modeling and load combinations to code checks and final report, so you spend less time switching tools and more time engineering.

  • Every material in one model

    Steel, cold-formed steel, wood, CLT, reinforced concrete and aluminum are analyzed and designed together, within a single, unified platform.

  • US and Canadian codes in one program

    Loads to ASCE 7 and NBCC, with design to AISC 360, CSA S16, NDS, CSA O86, ACI 318, CSA A23.3, AA ADM and CSA S157.

  • Automated load combinations and redesign

    ULS, SLS, fatigue and fire resistance combinations and live load reduction are generated automatically, and member redesign optimization finds efficient sections.

  • Advanced analysis with animated results

    Finite elements with plates and shells, P-Delta, nonlinear, buckling, response spectrum and seismic time-history analysis, with the Direct Analysis Method for steel.

Software reviews

Trusted by Structural Engineers Since 1986

What engineers say about SAFI™ structural software.

“The SAFI software was built with the engineer and designer in mind. The team has thought of every feature an engineer needs to design and optimize a structure. The program is very intuitive and easy to pick up. The support team is very responsive and knowledgeable. They can troubleshoot any modeling issue that comes up.”
Charles Vora, PEVeristic Technologies, Inc. · Houston, USA
“The SAFI software is one of the most suitable structural analysis and design tool for onshore and offshore rigs. I was fortunate to work in both environments and I find that it is closely tailored to the industry’s compliance. What can I say about customer support? Imagine that customer support is just a call away, always available and knows exactly what I need.”
Sugrim SagarM.Sc. P.Eng. · Texas, USA
“I don’t customarily provide reviews for software, nevertheless this is a special case. I have been using a variety of software in my 30-year structural engineering career (including all the big ones out there as well as some smaller lesser known ones). I must tell you that your SAFI software ranks up there with the best of them.”
Paolo M. Trevisan, P.Eng.Trevitech Consulting Ltd
