考虑约束作用的型钢混凝土柱轴心受压承载力计算

Jianzhu Gangjiegou Jinzhan
现行多数规范的型钢混凝土（steel reinforced concrete，SRC）柱轴心受压承载力计算未考虑型钢与钢筋的约束作用，导致计算结果偏保守。本文基于约束混凝土本构关系建立SRC短柱有限元模型，分析各材料的内力分布规律；结合已有文献试验数据和有限元参数分析结果，建立考虑约束作用的SRC长柱轴心受压承载力计算方法。研究表明：当SRC短柱达到轴压峰值荷载时，在型钢与钢筋约束作用下，混凝土平均应力可达到甚至超过其单轴抗压强度。通过引入约束系数可有效提升SRC短柱轴心受压承载力及稳定系数的计算精度 ...
