中文摘要:
      传统方法对高层建筑框架结构抗倒塌可靠性进行评估时,只是单纯的从整体角度进行分析,导致得到的结果不够精确,无法准确反映出高层建筑框架结构的抗倒塌能力。文章提出了基于增量动力分析的高层建筑框架结构抗倒塌可靠性评估方法,对高层建筑框架结构安全储备进行详细分析,获取建筑框架结构倒塌储备系数;在此基础上,采用增量动力分析法设定高层建筑框架结构抗倒塌能力系数,并根据该系数得到高层建筑框架结构抗倒塌可靠性评估流程。测试结果表明,所提方法得出的评估结果可信度较高,实现了高层建筑框架结构抗倒塌的准确评估。
英文摘要:
      The traditional methods used to evaluate the anti-collapse reliability of the high-rise building frame structures simply analyze the structures from the overall point of view, resulting in inaccurate results and inaccurate reflection of the collapse resistance of high-rise building frame structures. In this study, a method is proposed to evaluate the anti-collapse reliability of the high-rise building frame structures based on incremental dynamic analysis (IDA). Further, the safety reserve of a high-rise building frame structure is subjected to detailed analysis, and the collapse reserve coefficient of the building frame structure is obtained. The IDA method is used to set the collapse resistance capacity ratio of the high-rise building frame structure, and the anti-collapse reliability of the structure is evaluated according to the coefficient. The test results denote that the evaluation results obtained using the proposed method exhibits considerable reliability and that the collapse resistance of the high-rise building frame structures can be accurately evaluated.
