摘要
福建省某石结构体系经过鉴定,墙体承载力及抗震构造措施不满足鉴定标准要求,必须对墙体进行加固以消除安全隐患。依据抗震鉴定报告和现行规范标准要求,对比分析石砌体墙抗震加固方法的适用性,选择采用UHPC嵌缝加固法对石砌体墙进行抗震加固。通过墙体嵌缝加固设计,提出了具有嵌缝工作性的UHPC配合比,对加固前后石砌体墙的抗剪承载力进行验算分析。结果表明:UHPC嵌缝加固法可以明显提高石砌体墙的抗震性能,具有良好的推广和应用前景。
A stone structure system in Pingtan County,Fujian province was evaluated,and it was found that the bearing capacity of the wall and the seismic structural measures did not meet the requirements of the evaluation standard,and the wall must be reinforced to eliminate the safety risks.According to the identification results of buildings,the common reinforcement methods of masonry structure are compared and analyzed,and UHPC joint reinforcement method is selected for seismic reinforcement of masonry walls.The results show that the POM-UHPC surface strengthening method can obviously improve the compressive capacity and seismic performance of the masonry wall,and has a good prospect of popularization and application.
