Abstract

Rayleigh damping was used widely for dynamic analysis based on direct integration, especially for nonlinear analysis. Compared with Rayleigh damping, modal damping is considered more reasonable as it can simulate the damping of each mode accurately in a large range of frequency. Though those two parameters of Rayleigh damping can simulate the damping of only two selected frequencies, numerical results show that for those structures with relatively long periods as high buildings, the contribution of those high frequencies can be negligible, proper frequency selection for Rayleigh damping can present satisfied damping effect.
