圆钢管钢骨混凝土柱的承载力参数分析
|
摘要
已有的关于圆钢管钢骨混凝土柱承载力参数的文献中,仅给出其大致的取值范围,并未考虑各参数间的交互影响和给出其最优取值,难以有效指导工程设计。建立了圆钢管钢骨混凝土受压柱有限元模型,并采用试验数据对其有效性进行了验证,根据正交试验原理设计了16个圆钢管钢骨混凝土柱计算模型,进行了非线性轴心受压分析。采用正交试验极值法分析了纵筋、箍筋、钢骨、混凝土强度和截面尺寸等参数对承载力的影响,得到了纵筋配筋率、箍筋体积配箍率、钢骨含钢率和混凝土强度等级等参数的最优取值和最佳取值范围,以及所适宜的柱截面尺寸。
The research on the bearing capacity of steel reinforced concrete(SRC)columns with circle steel tubes has only given the approximate range of the parameters. It did not take into account the interaction between the parameters and gives the optimal value. It was difficult to guide the engineering design effectively. The finite element model of SRC columns with circle steel tube was established, and the validity was verified with the experimental data. According to the principle of orthogonal test, 16 steel tube reinforced concrete columns were designed and the nonlinear axial compression analysis was carried out. The effects of parameters such as longitudinal reinforcement, stirrup, steel, concrete and cross-sectional dimensions on the bearing capacity were analyzed through extreme value analysis method of orthogonal experiment. The optimal value and the best range of values for the longitudinal reinforcement ratio, stirrup rate, steel tube ratio,and concrete strength grade were obtained, and the appropriate column cross-sectional dimensions was also given,for reference.
