摘要
框架结构传力明确,结构布置灵活,适用性强,能够提供大空间,并能够根据需要对空间进行灵活分隔,教学 楼、办公楼、多层住宅楼等建筑大多数被设计成框架结构.除了在高层建筑中应用较少,框架结构已经成为应用最广 泛的结构类型.框架节点作为结构关键的传力部位,也是结构中最薄弱、最易损伤的部位.该文以框架结构中节点为 研究对象,用ABAQUS有限元软件建立了 3个有限元模型,其中1个为对比试件,1个采用碳纤维布,1个采用纤维 布与角钢加固.通过模拟分析发现采用不同类型的加固方式均能够有效提高节点核心区抗剪性能,提高节点承载力 与延性,耗能能力得到提高,从而提高了结构的抗震性能.
Force framework structure clear,the flexible structure arrangement, applicability,can provide large space,and can according to the need for flexible space space,teaching building,office building,multi-storey buildings, etc. Most of the building was designed in frame structure. In addition to having fewer applications in high-rise buildings, the framework has become the most widely used structure. The frame node is the key trans-mission area of the structure, and is also the weakest and most vulnerable part of the structure. Based on the node in the structure as the research object,using the finite element software ABAQUS finite element model is estab-lished for three,one for contrast specimen,a CFRP,CFRP with angle steel reinforcement. Through simulation analysis using different kind of reinforcement method can effectively improve the shear shear performance, im-prove the bearing capacity and ductility,energy dissipation ability was improved,so as to improve the seismic performance of the structure.
