摘　　要：作为一种新的组合结构形式,维增强塑料(GFRP)管约束混凝土具有许多优于其他传统的结构形式的特点,包括突出的抗腐蚀性、良好的延性和抗震性能。现有的大量的关于GFRP管约束混凝土的研究都是基于小尺寸试验的基础上的。进行了一批足尺寸GFRP管约束混凝土短柱轴压试验,试验结果再次验证了GFRP约束混凝土所具有的优良的抗压性能。同时,试验结果也为可靠的预测足尺寸GFRP约束混凝土的应力-应变形为提供了有效的依据。FRP-confined concrete, a new form of hybrid structural members,possess many important advantages over conventional structural members, including their excellent corrosion resistance as well as excellent ductility and seismic resistance.To enable reliable design of confining FRP jackets, the stress-strain behavior of FRP-eonfined concrete subjected to axial compression needs to be properly understood and modeled.A large amount of research has been conducted on them,but the existing experimental studies have been limited to the testing of small-scale speci- mens.Made the series of full-scale axial compression tests on GFRP confined concrete short columns.These test results confirm the excellent axial compressive response of GFRP-confined concrete as initially expected.Additionally, the stress-strain behaviour of full-scale GFRP-confined con- crete is properly identified by these test results.
