Elasto-plastic dynamic analysis on transfinite inclined structure

According to Science Museum in Kelamayi, the design goal was proposed for this transfinite inclined structure. The nonlinear properties of the materials were considered, and the nonlinear analysis method was used. Seismic reaction analysis of frame-shear wall structure was carried, especially the nonlinear reaction under rare earthquake. The results under rare earthquake show that the maximum interlayer displacement angle is less than the limit value 1/100. The structure is safe and reliable under rare earthquake. Shear wall is elastic and no plastic hinge appears, useful for the development of energy dissipintion. Plastic hinges are found in coupling beams, frame beams and sprags. Plastic hinges in coupling beams have deeply developed, which are useful for the development of energy dissipation. Plastic hinges in frame beams and sprags are not so serious, and these components can be used without repairing, while the coupling beams have to be repaired after rare earthquake.
