摘要
利用有限元软件ABAQUS建立了GFRP管约束混凝土短柱的有限元模型,得到了有无GFRP管约束混凝土柱、轴压比、管壁厚度、长细比、混凝土强度等级等不同因素对构件滞回性能的影响规律。研究表明:GFRP管改善了核心混凝土的强度和变形能力,提高了柱的延性和耗能能力,抗震性能明显提高。
The finite element models of the short GFRP tube-confined concrete column were established in ABAQUS software,and the influences of different factors on hysteretic behavior of components were obtained such as GFRP tube,axial compression ratio,tube thickness,slenderness ratio and concrete grade. The study shows that the GFRP tube increases the strength and deformation capacity of core concrete and improves the ductility and energy dissipation capacity of columns,so the seismic performances of columns are advanced.
