摘要 建立了高强混凝土偏压柱有限元数值模型,分析了箍筋的间距及配箍形式对构件核心区混凝土应变及承载力的影响.结果表明,混凝土的延性和变形受箍筋强度的影响,成较为显著的正相关.高强箍筋在构件破坏阶段具有较高的安全贮备,可对核心区混凝土提供有效约束,但在正常使用状态下箍筋间距和配箍形式对构件延性的影响更大. A high strength concrete column bias finite element numerical model is established, and the influence of the reinforcement spacing of stirrups and form on the strain and bearing capacity of core concrete of components is analyzed. The results show that the ductility and deformation of the concrete are influenced by the strength of the stirrup, and are positively correlated. With high security reserves, high-strength stirrup in component failure stage can improve the core concrete effective constraint, but under the normal operation condition the reinforcement and stirrup spacing form have a greater influence on component ductility.
