摘 要:
本研究将国内外设计规程中有关钢管混凝土柱轴压承载力的计算方法,用于计算钢管再生混凝土轴压短柱承载力,并将计算结果与试验结果(其中包括21根方钢管再生混凝土柱以及49根圆钢管再生混凝土柱)相比较,找出与实验值最为接近的计算公式,并利用一次二阶矩法(JC法)进行可靠度校准.结果表明:采用规范CECS28-2012给出的轴压承载力计算公式计算钢管再生混凝土短柱的轴压承载力,试件在大部分荷载作用下,能够满足《建筑结构可靠度设计统一标准》有关承载能力极限状态可靠指标的要求。

摘 要:
This paper uses domestic and overseas formulae to calculate the bearing capacity axial compression short columns of steel tube recycled concrete,and to compare the calculated results with the test results(including 21 square columns and 49 round columns)to find out the most accurate calculation method.The first-order second-moment method(JC method)was used to calibrate the reliability of the formulae.The results showed that using axial compression bearing capacity calculation formula given by CECS28-2012,the specimen under most of the loads can meet the reliable index requirements for the limit of bearing capacity as stipulated in the Unified Standard for Reliability Design of Building Structure.
