In structural steel projects, the transition from design to fabrication is a common source of coordination challenges. One of the biggest pain points? Connection design. Whether it’s miscommunication on end reactions or unclear design intent, connection assumptions can break down in the gap between engineering and detailing. By using RISA-3D and RISAConnection—and leveraging direct integrations with SDS2 and Tekla Structures—structural engineers can streamline the handoff to fabricators, reduce errors, and improve collaboration. This post walks through how to support real-world coordination using these tools in practice. 1. Model and Analyze the Steel Frame in RISA-3D Start by building your structural steel frame in RISA-3D. Define geometry, assign member sizes, apply loads, and analyze the model. Once you're satisfied with the analysis results, RISA-3D provides the connection forces—axial, shear, and moment reactions—for each member end. 2. Export Connection Forces to RISAConnection Next, send selected members and their design forces to RISAConnection. This direct integration eliminates the need to manually transfer loads or recreate geometry. Once in RISAConnection, you can: Choose from a library of shear, moment, and braced connections Model the full geometry, including bolt patterns, welds, and gusset plates View pass/fail results for each limit state, with clear failure mode…

Last week, RISA employees spend two days volunteering at the Second Harvest Food Bank of Orange County, CA. Both days were spent at the Food Distribution Center, where staff and volunteers worked together to sort, package and distribute enough food to feed 250,000 men, women and children each...
Tension or Compression (T/C) Only members are commonly used in steel buildings when modeling braced frames that resist lateral load.
When modeling building structures using steel or composite steel floors, engineers typically utilize rigid diaphragms to distribute lateral loads (wind and seismic) to lateral load resisting elements such as shear walls, moment frames and braced frames. Rigid diaphragms represent a plane of very...
When using semi-rigid diaphragms in a RISAFloor/RISA-3D model, it is possible to see negative moments at the ends of pinned beams as a result of the link between the semi-rigid diaphragm and the beam-column connection.
RISA employees and their families recently participated in the 5th Annual Run4Water 5k at Mile Square Park where they raised over $6,400 towards the construction of wells that provide access to clean water to communities in Uganda. Congratulations to everyone involved and for more information about...
RISA-3D has two ways of automatically generating seismic-related Basic Load Categories (BLCs) which can be later referenced in the Load Combinations (LCs):
Connection design according to the new AISC 360-16 (15th Ed.) Steel Manual has now been implemented in RISAConnection. To select this code for your design, simply choose either LRFD or ASD from the Solution tab within the Global Project Settings. The addition of the new 15th Edition code, includes...
The most recent release of AISC 360-16 (15th Edition) includes changes to connection design for rectangular HSS shapes with applied concentrated forces. These changes are now included in RISAConnection v10.
