Abstract:The principle and main calculation steps of static nonlinear analysis are introduced. In order to use the method in tall buildings, the improved method for capacity spectrum is put forward. Some problems such as the influence of lateral load mode on capacity spectrum, the pull force of column under rare earthquake action, the decrease of demand spectrum on account of additional damping, are discussed. The static nonlinear analysis is applied to a super high rise building and its seismic performance is evaluated.
