Abstract:This study investigates the effect of underground floor(s) on seismic analysis of buildings. Because the underground floor(s) is more rigid relative to the super structure, some codes have stated that in the seismic analysis of such buildings the base is defined as the top of underground floor(s). A parametric study was established using the response spectrum analysis method. Finite element simulations are conducted using ANSYS program to investigate the effect of underground floor(s). Results are presented fo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
