| 摘 要： | 旨在通过ANSYS模拟GFRP管混凝土柱在低周反复荷载下的滞回性能，探讨其在地震作用下的强度、刚度和延性等力学性能的变化规律．采用有限元软件ANSYS得到构件的滞回曲线，采用软件origin对滞回曲线所围成的面积进行积分，研究结果表明试件随着长细比、径厚比、轴压比的增大，试件的延性退化显著，耗能能力变差，抗震性能降低．

| Abstract: | The purpose of this paper is to simulate and observe hysteretic performance of GFRP tube con- crete column under low reversed cyclic loading through the ANSYS, to discuss the under seismic action of the mechanical properties such as strength, stiffness and ductility of its rules of change. Using the finite element a- nalysis software ansys to get the hysteretic curves of the components, integrating the hysteresis curves for the area enclosed by using software origin. The results show that the specimens with the slenderness ratio, diameter - thickness ratio, axial compression ratio increases, the ductility of the specimens degrade significantly, the ability of the energy dissipation get worse, the seismic performance desrease. |
