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:
We often get asked: “Should I model my foundation as a slab or a spread footing in RISAFoundation?” While both are valid options, they use very different analysis methods, and the results can vary accordingly. In this article, we’ll walk through a side-by-side comparison, using the same modeled conditions to highlight how the results differ — and why. Model Setup To keep things consistent, we modeled a single condition in two ways: once with a spread footing and once with a mat slab. Mat Dimensions: 10' x 10' x 1' Pedestal: 1' x 1' x 2' Loads Applied: 40 k vertical dead load 10 k lateral dead load 15 k lateral wind load 14.79 k concrete self-weight Soil Overburden: Set to 0 for both elements Slab Mesh Size: Refined below default for more detailed results Load Combinations: A basic set used for clarity (see screenshots in RISAFoundation) Analysis Methodology Feature Spread Footing Slab Element Analysis Type Rigid body Finite Element Analysis (FEA) Support Model Single support point Compression-only springs (based on subgrade modulus) Mesh Behavior No submesh Submeshed into smaller plate elements Lever Arm for Lateral Loads Spread Footings: Full pedestal height + full footing thickness Slabs: Full pedestal height…

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:
