| Abstract: |
| In this paper, the energy response method is used to study the seismic response of external steel frame and internal concrete core tube mixed structures under earthquake actions. It discusses the earthquake total input energy of the structure under different ground motion parameters, and the regularity of the total input energy between hysteretic energy and damping energy. Through analyzing the distribution of hysteretic energy between different floors and between external steel frame and internal concrete core tube of the hybrid structure, it shows that the hysteretic energy is mostly located in the bottom layer of the shear wall, the region where shows severe damage under earthquake action. Through the study, it is found that the energy responses analysis method is quite effective to reflect the seismic response process and the elasto-plastic performance of the steel-concrete hybrid structure under earthquake inputs. |
