高强箍筋约束混凝土柱轴压试验研究

Studies on the Behavior of High-strength Concrete Columns with High-strength Reinforcement under Concentric Compression

对6个高强箍筋约束高强混凝土棱柱体试件进行了轴压抗压试验,对比分析了高强箍筋与普通强度箍筋约束钢筋混凝土柱轴心抗压的破坏过程及其形貌,并分析了影响约束混凝土柱在轴压下力学性能的主要因素,包括混凝土强度、配箍率、箍筋屈服强度以及配筋率等。研究结果可为高强箍筋在混凝土中的应用提供理论参考,并具有现实意义。

Six of high-strength concrete columns with high-strength reinforcement under concentric compression are tested, comparative analysis of the failure process of high-strength stirrup and ordinary strength stirrups confined reinforced concrete columns under axial compressive and morphology, together with the main factors affecting the mechanical properties of confined concrete under axial compression column are analysis,inclnding concrete strength, stirrup ratio, stirrup yield strength and ratio of reinforcement. The research results can provide a theoretical reference for the application of high-strength stirrups in concrete, and has the practical significance.
