AN EXPERIMENTAL STUDY ON THE SEISMIC BEHAVIOR OF CONCRETE-FILLED GFRP TUBE COLUMN
-
摘要: 为了研究GFRP(玻璃纤维增强聚合物)管混凝土结构的抗震性能,对低周反复荷载作用下的4个GFRP管混凝土柱和1个无套管约束的普通混凝土柱进行试验,研究其破坏形态及滞回性能,分析混凝土强度、轴压比等因素对柱延性的影响。试验结果表明,GFRP管混凝土柱具有良好的抗震性能。Abstract: In order to investigate the seismic behavior of a concrete-filled GFRP (glass fiber reinforced polymer) tube structure,repeat low cycle loading tests are carried out on four concrete-filled GFRP tube columns and one RC column. The failure shape and hysteretic characteristics are researched,and factors such as concrete strength and the axial load ratio that affected ductility of the columns are analyzed. Researches show that the concrete-filled GFRP tube columns have excellent seismic behavior.
