摘要/Abstract

摘要： 通过3根GFRP空心圆柱和3根GFRP-混凝土实心柱构件的侧向受弯试验,得到各试件的荷载-位移和荷载-应变关系曲线以及极限荷载。试验结果表明,随着纤维纵横向铺层比例的提高,空心构件的极限承载力以及抗弯刚度均有所提高,而实心构件仅增大极限承载力,但对抗弯刚度影响不大;长径比越小,空心和实心构件的极限承载力和抗弯刚度均增大,且实心构件相比于空心构件的承载力增长幅度较大。

Abstract: In this paper, 3 GFRP hollow cylinders and 3 GFRP cylinders filled with concrete were tested under the lateral bending. The load-displacement curve, the load-strain curve and the ultimate load of each specimen were obtained in the end. The test results show that, with the longitudinal-transverse ratio of fiber layers increasing, the ultimate load of both kinds of specimens and the bending stiffness of hollow specimens would be improved. However, it also indicates that the changes of fiber longitudinal-horizontal proportion have little influences on the specimens filled with concrete. What's more, with the length-to-diameter ratio decreasing, the ultimate load and the bending stiffness of both kinds of specimens would be improved, and the influence will become more evident for the specimens filled with concrete.
