SITE CLASS D (DEFAULT) FOR CODE-BASED SPECTRA ASCE 41
Posted: 17 Nov 2023, 07:06
Under Seismic Action Tab for ASCE 41-17 CODE-BASED SPECTRA, I hope you consider adding a SITE CLASS D (DEFAULT). If SITE CLASS D is selected as DEFAULT, site coefficient Fa should be at least 1.2 as provided by ASCE 7-16 Section 11.4.4, and this value is greater than the values in ASCE 7-16 Table 11.4-1 for Ss > 0.75. Looking forward to this inclusion. Thanks!
