摘要
圆钢管混凝土边框剪力墙是在普通混凝土剪力墙基础上研发的一种新型组合剪力墙。其将圆钢管混凝土柱和普通混凝土剪力墙进行了优势组合,形成多道抗震防线。为了解该组合剪力墙的抗震性能,进行了3个1/5缩尺试件的低周反复荷载试验,其中包括1个圆钢管混凝土柱框架结构、1个普通混凝土剪力墙和1个圆钢管混凝土边框剪力墙。在试验研究基础上,分析了圆钢管混凝土边框剪力墙的承载力、刚度及其退化过程、延性、滞回特性、耗能能力及破坏特征。研究表明:圆钢管混凝土边框剪力墙的抗震性能比普通混凝土剪力墙显著提高,且其承载力、抗震耗能能力均高于圆钢管混凝土柱框架和普通混凝土剪力墙承载力、抗震耗能能力之和,可用于高层和超高层建筑的抗震设计。
Shear wall with concrete filled round steel tube columns is a new kind of shear wall based on RC shear wall. The advantages of concrete filled round steel tube columns and RC shear wall were combined, and multichannel seismic fortification lines were formed in the new wall. In order to ascertain its seismic performance, three 1/5 scale specimens, including one frame with concrete filled round steel tube columns, one traditional RC shear wall, and one shear wall with concrete filled round steel tube columns were tested under cyclic loading. Based on the experimental study, load-carrying capacity, stiffness and its attenuation, ductility, hysteretic property, energy dissipation and failure phenomena of each specimen were analyzed. The results show that the seismic performance of shear wall with concrete filled round steel tube columns is obviously increased compared with RC shear wall, and its load-carrying capacity and seismic energy dissipation are higher than those of the total effect of the RC shear wall and the frame with concrete filled round steel tube columns can be used for seismic design of high building and extra-high building.
