A Review of Methods for Solving the Non-Classical Damping System
Damping is considered as a core parameter in structural dynamic equations.The classical damping as-sumption is acceptable for buildings with small damping and the relatively uniform distribution of mass and stiffness.However,the distribution of the dynamic characteristics of actual engineering structures is uneven,such as compos-ite materials,hybrid structures and vibration reduction and isolation structures.In the analysis of such structures,the assumption of classical damping structures brings significant errors to structural response analysis.In order to solve this issue,scholars have adopted the non-classical damping assumption.In order to obtain the structural dynamic re-sponse under the non-classical damping assumption,this paper discusses the structural dynamic analysis method,and summarizes its characteristics and scope of applicable.
