【摘要】 为研究GFRP管约束混凝土柱在轴心受压时的承载力,更好的应用于工程实际,采用有限元软件ABAQUS模拟分析不同的GFRP管管壁厚度、混凝土强度等级以及钢骨截面形式、钢骨强度等因素对GFRP管混凝土组合柱轴压力学性能的影响。研究结果表明:数值计算结果与试验结果吻合良好;增加GFRP管厚度、提高混凝土强度等级以及增加钢骨截面积等能提高组合柱承载力。更多还原

【Abstract】 In order to analyze the axial compression performance of GFRP tube composite columns filled with concrete,the influence of different thickness of GFRP tube,concrete strength and the section form and strength of steel are simulated by using finite element analysis software ABAQUS when the column under the axial compression. The results show that the numerical results are in good agreement with the experimental results; increasing the GFRP tube thickness can improve the core concrete strength and increase the strength and the bearing capacity of columns.更多还原
