Abstract

Linear eccentricity of a structure has great influence on aseismatic performance of the structure.Datalied and deep analysis of seismic response of eccentric structure has been made.It is enumerated two kinds of actual structures and is also established the momentum differentiating equation of coupling between the translation and torsion of single layer of asymmetric structure under earthquake.By adopting Rayleighs 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 eccentricity ratio and stiffness ratio.Finally, some valuable conclusions were drawn, which can supply references to engineering calculation and design of structural torsional response under earthquake.
- coupling between translation and torsion,
- eccentricity ratio,
- stiffness ratio,
- eccentric structure,
- time-history analysis
