梁端负筋施工切断框架结构承载性能分析

BEHAVIOR OF CONCRETE FRAMES IN SERVICE WITH CUTTING NEGATIVE FLEXURAL REINFORCEMENT

介绍某框架结构梁柱节点负筋被切断的质量问题的处理过程,处理过程中应用结构实荷试验,模拟结构受力状况,对结构进行整体载荷试验。载荷试验的对象从传统的单个构件变为整个结构,从测试单个构件的承载力到验证结构局部的承载力,突破了传统荷载试验的使用范围。采用THUFIBER程序,验证了结构极端承载性能。

This paper details the process of negative reinforcement of a frame structure joints cut quality problems, use of the structure during processing real load test simulated the situation of force structure, the structure of the overall load test. In this paper, the object of the load test from the traditional single component into the entire structure, and the carrying capacity of the individual components from the test to verify the bearing capacity of the structure of the local, the breakthrough in the use of traditional load test method. Extreme bearing capacity of the structure of THUFIBER program verification.
