Stiffness, Damping, and R in Wind & Seismic Design

This webinar focuses on the importance of stiffness reduction (cracking) factors, the assumed damping ratios, and the response modification factor (R) for estimating seismic demand in ASCE guidelines. The choices of these factors play a key role in determining the computed structures respond to wind and seismic forces. The session will help engineers better understand how to select their values to apply these concepts in code based design.  Their relevance in Performance Design (PBD) will also be discussed.
