How to Calculate ASCE 7-16 Seismic Load in StruSheets
Walk through Ss, S1, site coefficients, R and seismic weight to Cs and base shear using the converted IBC/ASCE spreadsheet.
Open Seismic Load · ASCE 7-16. Mapped accelerations and site coefficients stay editable so you can match the geotech report rather than a locked lookup.
Cs is limited by the equivalent-lateral-force upper bound and minimum. Base shear is Cs × W. UBC 97 jobs should use the separate UBC 97 seismic sheet.
