About

With S-FRAME, users can model, analyze, and design any structure regardless of its geometric complexity, material type, loading conditions, nonlinear effects, or design code requirements. S-FRAME’s automated framework generators build models quickly and import models with BIM and DXF import links, and users can maximize productivity with integrated concrete and steel design tools for design, optimization, code compliance, and report generation. With S-FRAME, users can quickly define structures using modeling automation to generate regular framework structures, and standard or custom trusses, and use clone tools to replicate all or part of the model. Additionally, users can save modeling time by importing existing BIM and DXF models. S-FRAME’s advanced meshing tools create the finite element mesh, giving users the power to generate detailed analysis results in their specific areas of interest. Users can explore those areas of interest by easily converting members to multi-shell models.

About

CalcSteel is a web-based structural steel design and analysis platform built to make professional engineering tools affordable and accessible.
