摘要:
本文基于双剪统一强度理论,在忽略钢管对外混凝土侧向约束力的情况下,提出计算简便且同时适用于FRP-混凝土 - 钢管空心组合圆柱与实心组合圆柱的轴压承载力计算公式,将公式计算结果与试验结果对比,吻合较好.基于公式进一步分析了混凝土强度、FRP管厚度、钢管厚度和直径比等因素对该类组合柱轴压承载力的影响,为今后FRP-混凝土-钢管组合柱的设计与应用提供理论支持
Abstract:
Based on the twin shear unified strength theory and ignoring the lateral restraint effect of steel tube to external concrete, a simple calculation formula for the bearing capacity of the hollow and solid FRP-concrete-steel tube circular composite column is proposed in this paper, and the calculated results were in good agreement with the experimental results. Based on the formula, the influences of concrete strength, FRP tube thickness, steel tube thickness and diameter ratio on the axial bearing capacity of the composite column were analyzed, which provides theoretical support for the future design and applications of FRP-concrete-steel tube composite column
