Simpson Strong-Tie®Yield-Link® Moment Connection Available in RISA-3D
The release of RISA-3D Version 19 includes the introduction of Yield-Link® Moment Connections, developed in conjunction with Simpson Strong-Tie®.
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…

RISAConnection v11 now includes the ability to design Column to Beam Column Cap Flange Plate Moment Connections according to AISC 360. This widely requested feature allows users to define the beam as a wide flange and the column as either a wide flange, tapered wide flange or HSS tube. To begin,...
Wide Flange beam to HSS Tube column moment connections can now be designed in RISAConnection version 9 with both the US and Canadian design standards. HSS tubes may be selected as the supporting column member on either of the two moment connections:
Wide Flange Beam to HSS Tube Column Moment Connections can now be designed in RISAConnection version 9. HSS tubes may be selected as the supporting column member on either of the two moment connections:
RISAConnection v8 now offers weak axis moment connections with beams framing into the web of a wide flange column. Previously, connections were only permitted to frame into the column flange. This additional feature will allow users to change the orientation of their wide flange column.
