摘要
有效提高混凝土结构的极限承载力、延长混凝土结构的破坏过程是工程界一直关注的重点问题。本文总结分析了FRP增强混凝土、钢筋增强混凝土、纤维增强混凝土以及超高韧性水泥基复合材料增强混凝土的断裂性能。结果表明:FRP、钢筋、纤维、UHTCC四种增强混凝土结构对其起裂荷载的改变相对较小,但均能有效改善结构极限承载力,延长结构失稳破坏过程,提高结构的安全性。
Effectively improving the ultimate bearing capacity and extending the destruction process of concrete structure is an important issue that draws great attention. The fracture performance of FRP reinforced concrete, steel reinforced concrete, fiber reinforced concrete, and UHTCC reinforced concrete are summarized and analyzed. The results show that the crack propagating loads of four reinforced concrete structure are changed little relatively, the ultimate bearing capacity can be improved effectively, the failure process can be extended, and the structural safety be improved.
