摘要:
钢骨-方钢管混凝土柱是一种组合柱设计模式,采用切线模量理论对该组合柱轴向受压稳定承载力进行分析.以核芯混凝土、方钢管和钢骨的应力-应变模型为基础,通过纵向变形协调和内外力平衡条件建立组合柱切线模量临界载荷的计算方法.由于核芯混凝土的应力-应变模型包含了方钢管的约束作用,因此该方法体现了组合柱中钢与混凝土之间的相互影响.7组轴心受压钢骨-方钢管混凝土长柱和41组方钢管混凝土长柱的试验结果表明,该方法可对轴压组合柱的稳定承载力给出良好预测.
Abstract:
Square steel tube column filled with steel-reinforced concrete is a new design model of steel-concrete composite columns. Tangent modulus theory was introduced to determine the stability capacity of this new type of composite columns subjected to axial load. Based on the stress-strain models of the core concrete and the steel,the calculation method of the critical load of the axial-loaded composite columns was established through the longitudinal strain compatibility and force equilibrium condition. Because the confinement effect of the square steel tube was involved in the stress-strain relationship of the core concrete,this method could allow for the interaction between the steel tube and the concrete. Comparison between the theoretical and experimental results for 7 square steel tube slender column specimens filled with steel-reinforced concrete and 41 square steel tube slender column specimens filled with concrete shows that this method can give a favorable prediction for the stability capacity of the composite columns.
