填充墙钢筋混凝土框架结构系指钢筋混凝土框架结构中为了围护或分隔房间在柱间嵌筑砖或其它砌块填充墙体而形成的一种复杂组合结构。已有的研究表明,填充墙对框架结构的承载力、刚度、变形性能及整个建筑物的动力特性均有很大的影响。目前中国的设计规范中对于填充墙与框架的协同工作无量化的设计方法。汶川大地震中大量填充墙框架结构发生不同程度的损坏,该类建筑的表现极大地丰富了人们对其抗震性能的认识。详细介绍了地震中填充墙框架结构的各种表现,试图分析其破坏机理,在此基础上为该类建筑物的抗震设计提出建议。
Filled-wall Reinforced concrete frame structure refers to a complex composite structure formed in a reinforced concrete frame structure to enclose or divide a room between columns, or to fill the wall with other blocks. Some studies have shown that infilled walls have a great impact on the bearing capacity, stiffness, deformation performance of the frame structure and the dynamic characteristics of the entire building. At present, China’s design specifications for infilled walls and frame work together to quantify the design method. The mass infill wall frame structure in Wenchuan earthquake occurred different degrees of damage, the performance of such buildings greatly enriched people’s understanding of its seismic performance. In this paper, the various performances of infilled wall frame structure in earthquake are introduced in detail, and the failure mechanism is analyzed. Based on this, some suggestions for the seismic design of such buildings are put forward.
