摘要
文中通过试验得到GFRP约束下混凝土空心柱的简化计算公式。对6个GFRP约束下混凝土空心柱进行轴压试验,计算出试验承载力。基于现有的研究成果,改进后计算得到与试验相符合的理论值,试验值与理论值吻合度较好。最终成功得出GFRP约束下混凝土空心柱的轴压承载力的简化计算公式。
To obtain the simplified calculation formula of concrete hollow column confined by GFRP,six concrete hollow columns confined by GFRP were tested under axial compression to obtain the bearing capacity.Theoretical values derived from the improved calculation based on the experiment results are consistent with the experimental results.Finally,a simplified formula for calculating the axial bearing capacity of concrete hollow columns under GFRP constraints is obtained.
