摘要/Abstract

摘要： 纤维增强复合材料(FRP)加固技术在砌体结构加固、修复中被广泛应用。大量研究表明,采用FRP加固轴心受压砖柱可显著改善构件的脆性特性,提高其承载能力和延性。本文回顾并总结了国内外学者对FRP加固砌体砖柱的轴心受压试验研究和理论分析,并对现有FRP加固砖柱的轴心受压性能研究进行了总结,整理出不同截面类型的砌体砖柱有效约束区面积的计算公式,总结了各学者提出的FRP加固砖柱的理论模型和FRP加固砖柱承载力与极限强度的计算公式。针对目前FRP加固砌体砖柱的研究现状,提出存在的缺陷与空白,为下一步的研究提供参考。

Abstract: Fiber reinforced composite (FRP) reinforcement technology is widely used in masonry structure reinforcement and rehabilitation. A large number of studies have shown that FRP can significantly improve the brittleness, bearing capacity and ductility of the masonry components. This paper reviews and summarizes the research and theoretical analysis on the axial compression test of FRP reinforced masonry column, introduces the research on the axial compression performance of FRP reinforced brick column, and sorts out the calculation formulas of the effective constraint area of different section types of masonry brick column. The calculation formula of the bearing capacity and ultimate strength of FRP reinforced brick column are summarized as well as the theoretical model of FRP reinforced brick column. Finally, the defects and blanks are put forward to provide reference for future research according to the current research status of FRP reinforced masonry brick column.

Key words: FRP, masonry column, axial compression, review
