| Abstract: | Detailed and deep analysis to seismic response of stiffness eccentric structure and quality eccentric structure has been made in the paper. The momentum differentiating equation of coupling between the translation and torsion of single layer of asymmetric structure under earthquake was established. By adopting Rayleigh's damping model and using time-history analysis(Wilson-? Method),the linear elastic analysis of the structure was made,and the earthquake response and dynamic characteristics of the structure model were calculated under different asymmetric rates.Finally,the article draws some valuable conclusions,which can supply references to engineering calculation and design of structural torsional response undere arthquake. |
