摘要
自复位结构体系是满足性能化设计要求的一种新型结构体系,除了能够保证结构在罕遇地震下不会倒塌外,还能够有效限制结构震后的残余变形。在进行有限元模拟方法的试验验证后,建立七层双跨摇摆自复位结构体系模型,分析结构体系在小震、中震和大震下的抗震性能,研究认为多层双跨摇摆自复位结构体系能够保证其在地震作用后仅替换耗能器即可继续使用,为震后结构的修复节省了成本,具有很好的工程应用前景。
The self-centering structure ment of the performance-based design. system is a new type of structural Except that the structure will not system which can satisfy the requirecollapse under the severe earthquake, the new system also can effectively limit the residual deformation of structure. Based on the finite element simulation method after the test, this paper established a seven-layer double-span rocking self-centering steel braced frame system, to analyze the seismic performance of structure system under small, medium and severe earthquakes. Analysis results showed that this double-span rocking self-centering structure system could hold its function after the earthquake, this structural system would save the cost of repair and maintenance, and have the good prospects for the future engineering projects.
