CFRP加固石质文物受弯承载力研究

Experimental study on flexural capacities of lithoid cultural relic reinforced with CFRP

结合西岳庙—天威咫尺石牌坊加固工程实例,利用CFRP加固技术对石质矩形梁进行了受弯试验,对比分析了加固前后石梁的破坏形态、承载力以及跨中挠度,指出CFRP加固石质文物后,其破坏形态由正截面脆性破坏转化为斜截面延性破坏,其剩余承载力和变形能力得到了显著提高。

Combining with Xiyue Temple-Tianwei near stone arch reinforcement engineering, the use of CFRP strengthening technology with rocky rectangular beams in bending test, comparative analysis before and after reinforcement Shiliang failure pattern bearing capacity and mids-pan deflection of CFRP reinforcement after stone relics, the failure pattern by the brittle failure of normal section into inclined section ductile fracture, and the residual bearing capacity and deformation capacity increased significantly.
