| 摘要≠ | 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. | Pushover analysis is a nonlinear static method for assessing seismic structural performance. Introduced by Fajfar in 1996 as part of the N2 method, it progressively increases lateral loads on a structure until it reaches a target displacement, revealing how structures deform and yield under seismic events. |
