| 摘 要： | 利用通用有限元分析程序ANSYS10.0对轴心受压型钢混凝土柱(ACSRCC)在火灾高温下截面应力分布进行了数值模拟分析,获得了ACSRCC截面的应力场分布,并对2种结果进行了对比。基于不同材料应力的转换原理和叠加原理,提出了火灾高温下ACSRCC截面应力的数值计算方法,计算结果与模拟分析结果大致吻合。最后研究了型钢保护层厚度等因素对火灾高温下ACSRCC力学性能的影响规律。

| Abstract: | Based on the fact that building material's strength degeneration rule in domestic and overseas are different under the high-temperature fire,with finite element analysis program ANSYS10.0,and based on stress analysis of numerical simulation on the axial compression steel rein forced concrete column(ACSRCC) under high-temperature fire,the thermal stress distribution of cross-section is derived and the two results are compared.Based on the conversion principle of different materials stress and the principle o... |
