Formally known as , this software is a dedicated 3D connection design and review tool. Unlike general FEA programs, RISAConnection is rule-based, adhering strictly to AISC 360 (American Institute of Steel Construction) and the AISC Steel Construction Manual, including seismic provisions (AISC 341).
A recent project involved the design and construction of a 50-story high-rise building in a seismically active region. The structural engineer used RISA Connection Software to design and analyze the connections between the building's columns, beams, and foundation. The software was used to optimize the connection designs, taking into account factors such as strength, stiffness, and ductility. The results showed that the use of RISA Connection Software reduced the overall construction cost by 10% and saved 20% in engineering design time. risa connection software
