HYSTERETIC BEHAVIOR OF CIRCULAR RC COLUMNS CONFINED WITH FRP JACKETS
-
摘要: 以轴压比和含FRP率为基本参数,进行了4根FRP约束圆钢筋混凝土柱以及3根圆钢筋混凝土柱滞回性能的试验研究,分析了轴压比和含FRP率对构件承载力、延性、刚度以及耗能性能等的影响。Abstract: Four circular R.C.columns confined with fiber-reinforced polymer (FRP) jackets and three circular R.C.columns were tested under constant axial load and cyclically increasing flexural loading.The main parameters in the test are axial compressive ratio and FRP ratio,and the influences of those parameters on the strength,ductility,stiffness,and energy dissipation are also investigated through analysis of hysteretic skeleton curves.
