FRP加固砌体结构的研究与应用

外贴纤维增强高分子聚合物复合材料（FRP）加固技术近年来在砌体结构的修复加固中得到应用．外贴FRP加固技术既适用于墙体局部开裂的加固又适用于墙体承载力不足的加固．介绍了近年来，国内外学者研究、开发和应用FRP材料进行砌体结构加固的试验和理论研究进展，详细介绍了FRP加固砌体结构抗剪、抗震、平面外抗弯性能以及FRP与砌体黏结性能研究进展．研究成果表明，外贴FRP加固可以提高砌体结构的抗剪和平面外抗弯极限承载力，改善结构的抗震性能，避免了由于砖砌体的脆性破坏而导致整体结构的突然破坏．同时介绍了欧洲古建筑采用FRP进行修复加固等FRP加固砌体结构工程应用情况．在总结以往研究成果的基础上提出了有关设计、施工建议，供实际加固改造工程应用参考．

Research and application of FRP reinforced masonry structures

FRP laminates are being successfully used for strengthening of existing masonry structures because of their superior properties. State-of-the-art survey of the experimental study and theory research on masonry walls strengthened with FRP composites were discussed. The shear properties, anti-seismic performance, large eccentric compression performance and interface bond behavior between FRP sheet and masonry wall strengthened with FRP composites were analyzed. Research results indicate that performances of FRP strengthened masonry structures are improved obviously in terms of seismic resistance, shear resistance and ultimate flexural bearing capacity under large eccentric compression. The application of such strengthening procedure to ancient masonry structures buildings with bonding FRP sheets was introduced too. At last, several conclusions were obtained, and they are valuable for references to design, construction and practical engineering.
