Résumé	Response spectrum analysis is a linear modal method for estimating earthquake-induced forces and displacements in structures. Introduced by Housner in 1941, this approach uses design spectra that represent the maximum response of single-degree-of-freedom oscillators at different natural frequencies to compute the structural response by combining modal contributions.	Equivalent static analysis is the simplest seismic design method, representing earthquake effects as a single static lateral force applied at the center of mass or distributed over the building height. Standardized by SEAOC in 1959 and incorporated into modern building codes, it is the most commonly used method for designing regular buildings.
