Testing Study on the Bending Capacity of Stone Beam Reinforced with CFRP

After hundreds years damage, the disease of stone structure member is very severity, and so structure reinforcement has great significance. In this paper, the bending capacity of stone member reinforced with CFRP is studied through the test combined with the protective project of Huangsong Stele. The tests totally have six stone beams to study the mechanics performance and damage model of original and reinforced stone beam. The bending capacity theory of reinforced beam is discussed. The study results revealed that the bending performance of stone beam reinforced with CFRP can ameliorate greatly, and the destroy model change from brittle failure of normal section to ductile failure of oblique section, and the bend-resisting capacity of stone beam reinforced with CFRP can be enhanced greatly. But the enhanced range isn't direct proportion with the dosage of CFRP. The calculate formula of bending capacity got from theory deduce joint the test result, so it can be used to guide the design of fact project. So, the reinforcement of stone bending beam with CFRP have well effect.
