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®.
With the adoption of ASCE 7-22, the concept of a multi-period response spectrum has been added to seismic design requirements. While this provides more accurate hazard representation, it also means engineers need to generate and input additional site-specific data. This quick workflow shows how to gather that data from the ASCE Hazard Tool and use it in RISA’s site parameters table for seismic load generation. Why This Matters for Engineers? Multi-period response spectra reflect more realistic ground motion characteristics and will increasingly be required as jurisdictions adopt ASCE 7-22. By pulling site-specific values directly from the ASCE Hazard Tool, engineers can ensure compliance and avoid unnecessary assumptions. The multi-period approach can result in higher or lower design forces depending on the building’s period and site class, but it always provides more accurate seismic representation than the traditional two-point method. Download the latest versions of RISA that supports ASCE 7-22 below. Step 1: Generate Multi-Period Spectrum Data Go to the ASCE Hazard Tool. Enter your project location (address, coordinates, or site description). Select ASCE 7-22 as the building code. Navigate to the seismic hazard results and download/export the Multi-Period Response Spectrum data. Step 2: Copy Data Points into RISA Open RISA…

RISAConnection 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, choose the...
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.
