Abstract:Several American codes for seismic design are introduced, and analyzed the differences about the aims and the details among IBC 2006, UBC 1997 and Chinese GB50011—2010. At last, the earthquake forces are compared from IBC 2006, UBC 1997 and GB50011—2010 through an example.
Keywords:seismic design; earthquake; return period; influence coefficient; structural important factor; ductility factor
