| Abstract: | Liyuan No.1 building employed a new hybrid structure system,which was composed of CFST(Concrete-filled steel tube) columns,steel beams,concrete shear walls and concrete core tubes.In this paper,the seismic system reliability of steel and concrete hybrid structure was evaluated by calculating program on the basis of branch-and-bound method.The dead loads,the live loads and the wind load were treated as random variables and the Kanai-Tajimi filter is used to generate the frequency contents of the ensemble of artificial earthquakes in this study.The analysis results provide the basis of designing and optimizing the hybrid structure. |
| Keywords: | hybrid structure CFST column seismic system reliability |
