Abstract:
A method of static elasto-plastic analysis is applied to calculate the elasto-plastic deformation of high buildings under the seismic action.From the basic principle of static elasto-plastic analysis combined with characteristics of the structure in high buildings,an improved method of static elasto-plastic analysis including both the combination of multi-mode vectors and the instantaneous dynamic characteristics of the structure is presented.The calculation results show that the improved method of static elasto-plastic analysis is applicable to calculate the elasto-plastic deformation of high buildings under the action of earthquakes.Because the lateral stiffness in high buildings is smaller,the lateral displacement shape on elasto-plastic deformation under the seismic action is obviously influenced by the higher mode vectors of the structure.
