摘要
针对高强混凝土柱的大偏心受压极限状态,采用一次可靠度、二次可靠度和重要抽样法对其进行了可靠度分析。经过大量参数分析,讨论了各种影响因素对高强混凝土柱在大偏心受压极限状态的可靠指标的影响。通过对一个按我国现行规范设计的钢筋混凝土柱的研究发现:高强混凝土大偏心受压柱的可靠指标基本满足规范要求。
The reliability of high-strength concrete columns under large eccentric compression is analyzed by using FORM,SORM and IS. By means of a lot of parameter analyses,the changing rules of various factors on the reliability index of high-strength concrete columns under large eccentric compression are discussed. Based on a study of reinforced concrete column which is designed according to the current code of China it is found that the reliability index of high-strength concrete columns under large eccentric compression basically meet the requirements of specification.
