Seismic Design Parameter Changes from ASCE 7-16 to 7-22
The upcoming ASCE 7-22 standard introduces a new Multi-Period Response Spectra (MPRS) that replaces the two-period response spectra in the ASCE 7-16 standard. Site soil classes have also been redefined from the ASCE 7-16 six site classes to nine new site classes; the new classes are based more strongly on the shear wave velocity than previously, which will favor performing shear wave velocity measurements on more sites. This presentation compares the previous site classes and design spectra from ASCE 7-16 with the new versions in ASCE 7-22 at locations across the United States. Additionally, comparisons of the design earthquake spectra from ASCE 7-16, ASCE 7-22, and site-specific probabilistic seismic hazard analysis for 30 sites in the Los Angeles Metropolitan Area will be provided.

HSS Connections Made Easy – for Trusses and Moment Frames Webinar Series – Day 1: Weld Design for Hollow Structural Section Connections
Dr. Tousignant will summarize the rules used to classify HSS truss connections, and their potential limit states. Additional technical resources, such as AISC 360 and AISC Design Guide 24, will also be introduced for those wanting to learn more or apply the knowledge in practice. The remainder of the presentation will focus on the application of AISC 360 Section K5 – “Welds of plates and branches to HSS” and related considerations for fabrication and design.
