Webb8 aug. 2024 · Seismic design category from Section 11.6 of ASCE 7-16. For this structure, with Risk Category II, S D 1 = 0.402, and S D S = 0.708 the Seismic Design Category is D based on both tables 11.6-1 and 11.6-2 of ASCE 7-16. The Seismic Design Category will be used for redundancy factor ρ in calculating diaphragm design forces. WebbOur interpretation of the code’s implied nonstructural performance objectives related to seismic performance are summarized in Table 1-2. The nonstructural importance factor, Ip, is used to differentiate between the objectives for nonstructural applications in designated seismic systems and those applications deemed less essential. Webb3 okt. 2016 · As it can be seen from the above screenshot, in STAAD output SDS value is 1.708 which is almost same as USGS provided value (1.709). By Substituting SDS, importance factor and Response modification factor in the eqn. 12.8-2 of ASCE 7 2010 code, Cs is calculated as follows: Cs = SDS/(R/Ie) = 1.708/(3.5/1.25) = 0.61. christian bookstore huntington wv
