The seismic regulations for the seismic performance assessment of buildings use the maximum interstory drift, θ max, as a measure to control damage. This article presents a study of the seismic performance based on the θ max for steel buildings using Mexico's regulations and the RISK-UE and HAZUS guidelines. The capacity spectrum method is used to evaluate the performance of buildings with 3 different heights located in 4 cities in Mexico with different seismicity, as well as for soft and rock soil types. The HAZUS criterion is conservative in its assement of damage, while the RISK-UE criterion is more in line with the expected damage. The service state, S state , and the collapse prevention state, CP state , in Mexico's regulations are suitable for damage control, and are consistent with the damage proposed by the RISK-UE guidelines. In very high seismicity zones, the CP state for seismic actions equal to or greater than the expected, prevent building collapse; however, significant damage to buildings can still occur. The θ max of the CP state must be established for different seismic intensities and not only for building types.
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.
