Tóm tắt	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.	Incremental dynamic analysis (IDA) is a method that runs time-history analyses on a structure with a single ground motion record, progressively increasing the intensity until the structure reaches a specified performance level or collapses. Introduced by Vamvatsikos and Cornell in 2002, this approach efficiently generates fragility curves relating earthquake intensity to structural damage and collapse probability.
