摘要:

基于纤维增强复合材料(FRP)约束混凝土柱的相关研究,从FRP约束混凝土柱的应力-应变关系、轴心受压和偏心受压力学性能、抗震性能以及有限元数值模拟等几个方面,对FRP约束混凝土柱的研究现状和各方面的相关控制因素进行了系统阐述,重点分析了FRP 侧向约束强度、刚度、FRP类型、柱截面形状、未约束混凝土强度、倒角半径、截面长宽比等因素对约束效果的影响,为FRP加固混凝土柱的进一步研究提供了参考。

Abstract:

Based on the related research on fiber reinforcedpolymer(FRP)confined concrete column,authors presented the state-of-the-art review of FRP confined concrete column and gave a comment on some related factors from the following aspects: the relations of stress and strain, the axial compression, mechanics behavior of eccentric compression, seismic performance as well as finite element numerical simulations of FRP reinforced columns. Several key parameters impacting on FRP strengthening effect were discussed, such as lateral confinement strength, stiffness, the type of FRP, section shape of column, unconfined concrete strength, corner radius, length-width ratio of section, etc. The results provide reference to further research of FRP retrofitting concrete columns.
