Abstract

Abstract

The "three levels and two stages" seismic design method currently adopted in China allows structures to undergo plastic deformation under the action of earthquake. However, due to the complexity and uncertainty of earthquakes, structures and components have large residual deformation, which makes it difficult or impossible to repair after the earthquake. Therefore, the displacement-based seismic design method was adopted to calculate the earthquake force and design the self-centering frame, and the dynamic elastic-plastic time-history analysis of the structure was carried out. The results showed that when the self-centering frame joint design was completed, the self-centering ratio and the base shear V_Base of the whole structure were recalculated, which was less than 1% from the design base shear force, indicating that the design method had a good fit; according to the results of dynamic time-history analysis, it could be seen that the overall seismic performance of the structure was good, and there was no collapse damage, which could meet the seismic fortification requirements under rarely occurred earthquakes, and the seismic performance of the structure was better than that of cast-in-place joints.
