Study on Dynamic Analysis Methods for Non-Proportionally Damped Structural Systems

For the earthquake resistant analysis of actual engineering strictures,most of structural systems have the properties of non--proportional(non--classical) damping. The dynamic analysis methods for the system are developed systematically and comprehensively in this paper. For analyzing structural systems with variant degrees of the non--proportional damping, the improved complex modal method, the approximate decoupling method, the modal superposition pseudo--force method, the Ritz vector superposition methods and the high accurate and unconditionally stable direct integration schemes are presented.These methods are of good practical value and theoretical significance, and can be applied effectively to solve practical engineering problems.
