Site-Specific Ground Motion Procedures per ASCE 7-16 with ideCAD

How does ideCAD define horizontal elastic design spectrum for site-pecific ground motion, according to ASCE 7-16?


  • Due to the need for site-specific analysis for site class F, the user defines short-period and long-period site coefficients Fa and Fv.


Site response analysis has to be performed in accordance with 11.4.8.

When short-period site coefficient Fa and long-period site coefficient for a period of 1.0 seconds are defined, horizontal elastic design acceleration spectrum corner periods To and Ts are calculated, and the horizontal elastic design spectrum is created.
