What's New in RISAConnection v15.0.1?
RISA is pleased to announce the release of the latest of RISAConnection v15.0.1. The release of RISAConnection v15.0.1 incorporates the following enhancements and updates:
Light-framed construction has become increasingly prevalent in mid-rise and modular development, driven by its cost-efficiency, speed of construction, and adaptability. But with flexibility comes complexity. Engineers designing with wood and cold-formed steel (CFS) must navigate a unique set of challenges: diaphragm behavior, segmented shear walls, buckling sensitivity, and code-specific checks that differ from traditional hot-rolled steel or reinforced concrete structures. This article explores practical modeling and design approaches for light-framed buildings, focusing on how structural engineers can balance constructability, analysis clarity, and compliance with governing codes. Diaphragm Behavior: Not Always Rigid In light-framed buildings, flexible diaphragms are often assumed due to the nature of wood sheathing or light-gauge decking. However, as buildings increase in size and irregularity, this assumption deserves scrutiny. Flexible diaphragm assumptions work well in rectangular buildings with regular framing, but irregular load paths or large openings may require semi-rigid modeling to capture torsional behavior. Engineers should consider the influence of diaphragm stiffness when assigning lateral forces, especially in hybrid systems where part of the structure may be stiffer or tied into concrete cores. In projects where semi-rigid diaphragm analysis was warranted, integrating tools like finite element meshing helped visualize how in-plane stiffness impacted overall response—particularly in designs…

RISAFloor now includes the ability to design web openings (with and without reinforcement) for steel and composite steel beams according to the AISC design code. To learn more, view the video below. For more information about web opening design in RISAFloor, search Web Openings in the RISAFloor...
Version 20.0.2 allows users to integrate models between RISA-3D and SDS2, including model geometry, members sizes and end reactions.
RISAFloor Version 16 provides engineers the ability to analyze and design hot rolled steel WT and LL shapes. This functionality was previously implemented in RISA-3D and will allow users greater flexibility when designing their steel structures. Additionally, WT and LL shapes can be specified and...
Engineers choose RISA-3D and RISAFloor for the design of all types of steel structures. As a result, we are constantly improving the software and its acceptance of various types of design elements and materials. The latest improvement includes back-to-back hot rolled steel channels which are now...
The ability to design buckling restrained braced frames has been added to RISA-3D when you integrate your model from RISAFloor. In collaboration with CoreBrace, this new feature came as part of the release of RISA-3D v19.0.0 and RISAFloor v15.0.0.
RISAConnection Version 12 now supports skewed shear tab connections. With this enhancement, engineers have the option to skew a wide flange, a tapered wide flange or a channel beam with the following supporting members:
