摘要

摘要: 为探究圆截面碳纤维增强聚合物（CFRP）-钢管混凝土在压-扭荷载作用下的力学性能，结合8个CFRP-钢管混凝土试件进行压-扭静力加载试验，对试件的试验现象、扭矩-转角曲线、钢管与碳纤维的协同工作以及平截面假定进行了探讨；应用有限元软件建立模型进行对比，模拟结果与试验结果相吻合；以上述研究为基础，对构件进行了受力全过程分析；参数分析的结果表明，横向碳纤维层数、混凝土强度和含钢率对扭矩-转角曲线的形状无明显影响；横向碳纤维层数、钢材屈服强度、混凝土强度和含钢率的增加可以提高构件的承载力，适当的轴压比也可以提高构件的承载力；基于性能分析结果，得出圆截面CFRP-钢管混凝土的压-扭极限承载力方程，通过验证可知与试验结果拟合良好。

Abstract: For deeply understanding of the mechanical properties of concrete filled circular carbon fiber reinforced polymer (CFRP) steel tubular under compression and torsion, 8 concrete filled CFRP-steel tubular members under compression and torsion were conducted. The results of test observation, the torque-rotation angle curves, the coordination between steel tube and carbon fiber, and plane across-section assumption were analyzed. ABAQUS was used to simulate the torque-rotation angle and the failure modes. The simulating results coincided well with the test results. Based on above-mentioned study results, the whole loading process analysis was carried out. The results of analysis of parameters showed that the transverse carbon fiber layer, the concrete strength, and steel ratio had none obvious influence on the torque-rotation angle curves. Increasing the transverse carbon fiber layer, steel yield strength, concrete strength and steel ratio could improve the bearing capacity of members. The proper axial compression ratio could also increase the bearing capacity. Based on the performance analysis and a large number of calculation results, the equation for the bearing capacity of concrete filled circular CFRP-steel tubular under compression and torsion was proposed, the calculated results were in good agreement with the experimental results.
