【Abstract】 A response reanalysis approach of structure under harmonic or periodic excitation has been studied with original vibrating response. This method is made use of the matrix series expansion to construct modified structure′s vibrating response reanalysis approach based on mechanical impedance method. It is proved by an example that this method is very efficient.更多还原
