【摘要】 通过对钢-混凝土连续组合梁、钢管混凝土柱的荷载-位移滞回曲线试验结果的分析,提出了简化的适用于组合结构刚度退化三线型恢复力模型;根据所提出的恢复力模型及滞回规则,编制了地震弹塑性时程响应分析程序;结合算例,用所编制程序的计算结果与相关文献中的钢筋混凝土框架结构的计算结果进行了比较,验证了所编制程序的正确性。计算表明,此恢复力模型及程序能应用于钢-混凝土组合框架的弹塑性时程反应分析中,具有较高的工程应用价值。更多还原

【Abstract】 <Abstrcat>Based on hysteretic curve of load-displacement of concrete filled steel tubular column and steel-concrete composite beams, tri-linear restoring force model with consideration of rigidity degradation, which can be widely applied in composite structure, are proposed. According to the model and the cyclic rule , the program of elastic-plastic earthquake response are compiled. By taking an example of the steel-concrete composite frame structure , the rationality and correctness are testified by comparing the calculated result with the result of reinforced concrete structure in other paper, which shown the model and program have better value of engineering application and can be applied in elastic-plastic earthquake response of steel-concrete composite frame structure.更多还原
