摘要
考虑钢骨高强混凝土长柱在偏心荷载作用下的材料非线性、二阶效应、型钢与混凝土之间的粘结滑移以及型钢和箍筋对混凝土的约束作用等影响因素,对单向偏压钢骨高强混凝土长柱的变形和承载力进行了全过程分析.编制计算程序,给出其荷载与变形的关系曲线,计算结果与试验结果对比,二者吻合良好.
A nonlinear full-range analytical model on the steel reinforced high-strength concrete （SRHC） long columns submitting to eccentric compression was presented based on the influence of material nonlinearity, second-order effect, bond slip, the confining of the steel and the stirrup. Then, the curves of the load-deformation relation were obtained with the calculating program. The results of numerical analysis by the proposed method correlate weU with the results of the tests.
