摘要

摘要: 进行了4个钢管混凝土短柱标准火灾作用后轴压刚度和承载力及4个钢管混凝土纯弯构件标准火灾作用后抗弯刚度的试验研究，采用数值方法可有效地预测钢管混凝土火灾后轴压刚度和抗弯刚度的变化规律，并探讨了火灾后钢管混凝土轴压刚度和抗弯刚度的实用计算方法。

Abstract: Tests were performed of 4 concrete-filled steel tubular stubs and 4 flexural members after ISO-834 standard fire.A numerical method was developed to predict the changing of axial rigidity and flexural rigidity of concrete-filled steel tubular members after fire, with predicted results in a good agreement with test results.A practical method is suggested for calculating the rigidity of CFST axial and flexural members after fire based on the theoretical and experimental results.
