RISAConnection Software: A Technical Write-Up
Overview
RISAConnection is a dedicated steel connection design and checking software used by structural engineers. It operates as a standalone application but integrates seamlessly with RISA-3D and RISAFloor . The software automates the design of virtually every common steel connection type according to AISC 360 (American Institute of Steel Construction) and other international codes.
Unlike generic FEA tools, RISAConnection focuses on the critical interface between members—the "connection"—which is often the most complex and failure-prone part of steel design.
