摘要
为定量评估不同填充墙构造方法对钢筋混凝土(reinforced concrete,RC)框架抗震性能的影响,搜集整理国内外砌体填充墙RC框架拟静力试验数据,筛选出19篇文献中共68个数据较为详尽的试件作为样本,分析对比柔性连接填充墙、增强填充墙整体性及设置阻尼耗能装置三类构造方法对试件的峰值点承载力、初始刚度、位移延性系数和等效黏滞阻尼系数4个参数的影响程度。结果表明:相较于传统构造方法,柔性连接填充墙框架的承载力和刚度均有所下降,变形能力提升;增强整体性的方法可提升试件承载力、刚度和变形能力,可作为一种较好的既有框架结构的加固方法;设置阻尼耗能装置虽然结构的承载力和刚度有所降低,但提升了结构的变形能力和耗能能力,在建造成本可接受的情况下可作为新建建筑的韧性提升方案。
In order to quantitatively assess the effect of different infill wall construction methods on the seismic performance of reinforced concrete(RC)frames,domestic and foreign pseudo static test data of masonry infilled RC frames were collected,and a total of 68 specimens with detailed data in 19 literatures were selected as samples to analyze and compare the effects of three types of construction methods,namely,flexible connection of infill walls,integrity enhancement of infill walls,and installation of damping devices,on the strength,initial stiffness,ductility factor and equivalent viscous damping factors of the specimens.The results show that compared with the traditional construction methods,the strength and stiffness of specimens with flexible connection infill walls decrease,and the deformation capacity increases.The method of enhancing integrity can improve the strength,stiffness and deformation capacity,and it is a better method to reinforce the infill walls of existing buildings.The strength and stiffness of the structure with damping energy dissipation devices are reduced,but the deformation and energy dissipation capacity of the structure are improved,which can be used as a resilience improvement for new buildings if the construction cost is acceptable.
