FRP复合材料在土木工程中应用的研究进展

Research advance for application of FRP composites in civil construction

回顾了运用纤维增强复合材料(FRP)外部加固和修复土木工程结构的研究进展,重点介绍了试验和数值分析二方面的研究。综述了主要结构部件如梁、柱和梁柱联合体在加固后的弯曲、剪切、耐久、延展性等性质,简要讨论了这些构件的轴向、地震等结构行为。最后,对将来可能的研究方向作了评述。

Research advance on external strengthening in civil construction are made by using fiber reinforced polymer （FRP）. composites in this paper.Experimental as well as analytical and mtmerical research contributions have been focussed in the review.The properties, such as flexural, shear, durability, ductibility, of the main structural components （beams, columns and beam-column joints ） have been reviewed and structural behavior of each component is discussed briefly.Finally, general concluding remarks are made along with possible future directions of research.
