【摘要】提出了一个基于18参数的钢支撑滞回模型,可准确模拟普通钢支撑的滞回行为。以一典型RC框架教学楼的钢支撑加固为例,通过推覆分析和基于动力增量分析(IDA)的倒塌易损性分析,研究了普通钢支撑加固的效果。更多还原

【Abstract】 In this paper,a hysteretic model of conventional steel brace based on 18 parameters is put forward.The model could simulate the hysteretic behavior of conventional steel brace accurately.Then a typical RC frame that was closed to the epicenter and collapsed during Wenchuan Earthquake is analyzed.Push-over analysis and collapse fragility analysis based on incremental dynamic analysis are implemented to discuss the strengthening effect with steel braces.The result could be referred for the seismic collapse prevention design of RC frames.更多还原
