| Résumé≠ | Nonlinear time-history analysis is a numerical method that solves the equations of motion step-by-step in the time domain, using recorded or synthetic earthquake ground motions as input. Developed by Newmark in 1959, this approach captures the full dynamic response of structures including material nonlinearity, geometric effects, and energy dissipation mechanisms. | 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. |
