Seismic performance assessment based on the interstory drift of steel buildings

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
