Abstract

Abstract

Based on finite element software steel reinforced concrete ( SRC) frame - reinforced concrete ( RC) core tube structures with different structure characters were established． Main factors chosen as structure design parameters were wall integral coefficient，axial deformation coefficient and stiffness characteristic value． Elastio-plastic time history and nonlinear Pushover analyses of the structures were performed under bidirectional strong earthquake actions to examine the effects of designed parameters on the modes of energy dissipation and damage of SRC frame-RC core tube structures． Research results indicated that for the structure having smaller axial deformation coefficient，larger wall integral coefficient and smaller stiffness characteristic value，the energy distribution of the shear walls under rare earthquake might be not controllable． Furthermore，yield sequence of structure components and their development were studied． Moreover，reasonable damage mode of frame-core tube structures was proposed，and some design suggestions were given．
- SRC frame-RC core tube structure,
- seismic behavior,
- hysteretic energy dissipation,
- damage mode
