| 中文摘要: |
| 以钢管混凝土统一理论为基础,钢管混凝土柱构件采用3线型弯矩-转角滞回模型;钢梁采用双线型弯矩-转角滞回模型.使用非线性分析程序IDARC分析钢梁-钢管混凝土柱框架结构的恢复力特性曲线,程序结果和试验结果吻合良好.并进一步研究了轴压比、含钢率、混凝土强度和钢材强度等对骨架曲线的影响. |
| 英文摘要: |
| Based on the unified theory,trilinear and bilinear moment-rotation hysteretic model were used for CFST column and steel beam respectively.Nonlinear analysis program was employed to obtain the restoring force characteristic curve.Results obtained from the program are consistent with those obtained from the experiment.Furthermore,some parameters that affect the restoring force model of CFST structure have been studied,including axial compression ratio,steel ratio,material strength and so on.The results not only provide necessary theory basis for popularizing the CFST structure,but play a valuable role to seismic design of CFST structure. |
