| 摘 要： | 在统一强度理论和基本假定的基础上,考虑CFRP-钢复合管对核心区混凝土的侧向约束和外围钢筋混凝土套筒对极限承载力的贡献,推导CFRP-钢管混凝土核心轴压短柱的极限承载力公式。通过与文献中试验结果进行比较,验证理论公式的正确性,并进一步分析总套箍指标、钢管的套箍指标和CFRP筒的套箍指标对承载力的影响,为CFRP-钢管混凝土核心轴压短柱的极限承载力分析提供了一定的理论依据。

| Abstract: | Based on unified strength theory and some essential suppositions,the ultimate bearing capacity formula of concentrically compressed stub columns reinforced by concrete filled circular CFRP-steel tube is deduced,considering the restriction of CFRP-steel tube to inner concrete and vertical bearing capacity of outer reinforced concrete.The results of the proposed formula are found in good agreement with experiment results.In the last,the effects of the total confinement factor,confinement factor of steel tube ... |
