摘要: 采用纤维模型法,编制非线性计算程序,对偏压PVC-FRP管钢筋混凝土柱荷载-挠度关系进行全过程分析,并验证该计算程序的正确性。在此基础上,利用分析程序对影响PVC-FRP管钢筋混凝土柱力学性能的主要因素进行分析,得出FRP条带环箍间距、偏心距、FRP条带宽度、混凝土强度等级和配筋率等参数对偏压PVC-FRP管钢筋混凝土柱荷载-挠度关系曲线的影响规律,为PVC-FRP管钢筋混凝土柱在复杂应力状态下的受力分析奠定基础。

Abstract: To predict the whole process analysis of load-deflection relationship of PVC-FRP confined reinforced concrete columns under eccentric compression,a nonlinear program is developed by using fiber model method, and then the correctness of the calculation program is verified. Based on the program, the effect of major factors on the mechanical behavior of PVC-FRP confined reinforced concrete columns are analyzed. The influence law of the hoop spacing of FRP strips, eccentricity, the width of FRP strips, concrete strength and reinforcement ratio on the load-deflection relationship are obtained. This paper lays foundation for the analysis of PVC-FRP confined concrete column under complex stress state.

Key words: PVC-FRP confined concrete, fiber model method, eccentric compression, load-deflection relationship, numerical simulation
