纤维增强复合材料(FRP)加固混凝土柱研究进展

RETROFITTING AND STRENGTHENING OF CONCRETE COLUMNS WITH FRP:A STATEOF-THE-ART REVIEW

纤维增强复合材料(FRP)在混凝土结构加固中得到了广泛的应用。依据国内外相关资料,从FRP材料类型与施工方法、试验加载形式、混凝土柱截面形式、加固后柱的强度、延性及破坏模式等方面,对FRP加固混凝土柱的大量研究成果进行了总结评述,并对今后可能的研究方向提出了展望。

Fiber reinforced polymers(FRP) have been used extensively in the retrofitting and strengthening of concrete structures.A review of state-of-the-art of retrofitting and strengthening of columns with FRP is presented which focused on several aspects including different FRP materials and construction methods,loading type in the test,section shape of column,strength/ductility and failure modes of columns after being retrofitted or strengthened.The research results and achievements are discussed.In the end,some studies that should be developed in the future are put forward.
