钢框架住宅主体结构本身抗震性能良好,故围护墙板与钢框架的连接方式对房屋整体的承载能力、抗震性能、延性等具有重要影响,结合东北地区的气候条件、工程应用现状,优化了围护墙板构造,设计了2种柔性螺栓连接方式。在理论研究的基础上,制作了1∶2缩尺试件,进行了围护体系整体抗震性能的试验,对比分析得到了不同围护体系的承载力、耗能、延性等指标,验证了柔性连接的明显优势,为钢框架结构的工程应用提供了参考。
The main frame structure of steel frame house itself has good anti-seismic performance. Therefore, the connection between the retaining wall plate and the steel frame has an important influence on the bearing capacity, anti-seismic performance and ductility of the whole house. Combining with the climatic conditions in Northeast China and engineering application, Wrap wall structure, designed two kinds of flexible bolt connection. On the basis of theoretical research, a 1: 2 scale test specimen was made and the overall seismic performance of the enclosure system was tested. The indexes of bearing capacity, energy dissipation and ductility of different containment systems were compared and analyzed. The obvious advantages of the connection provide a reference for the engineering application of steel frame structure.
