Title: Research on structural energy response's vertical distribution based on energy response spectrum
Abstract: In order to study the energy distribution rule along the floor,research on story energy response is carried out for the layered model,and the application of energy response spectrum in the elastic story energy response is accomplished.Applicability of the mode-uncoupled simplified story energy is assessed,and the expression of structural elastic energy response's vertical distribution is forwarded thereafter.The concepts of consistent modal shape and its corresponding stiffness-mode shape are given,with their physical significance to story energy's vertical distribution expatiated.Numerical examples show the accuracy of the proposed method in estimating the maximum story energy response,and the first modal energy's participation takes the most part generally,especially for the deformation energy.
