钢筋混凝土框架节点研究及加固方法

Research on Framework Nodes of Reinforced Concrete and Strengthening Metheods

框架节点是框架结构中重要组成部分,充分理解框架节点受力机理的情况下,才能更加全面分析框架节点载地震作用下抗震性能。框架节点的加固理论及方法是目前工程研究领域重要方向,采用合理有效的加固方法对框架结构进行加固处理,能使现有结构构件满足使用要求。

The framework nodes is an important part of the framework structure, under the condition of fully understanding of the framework node fundamental mechanism, we can make to a more comprehensive analysis of the framework node upload earthquake under seismic performance. Reinforcement theory and method of frame joints is an important direction in the field of engineering research, reasonable and effective reinforcement methods are taken to reinfroce the frame structure ,which makes existing structural elements meet the requirements. The paper mainly introduces power transmission mechanism of framework nodes, the seismic performance, reinforcement situation framework nodes at present.
