为了进一步改进 RC 的地震表演,砍墙,一新合成砍有水泥的墙充满了钢试管(CFT ) 柱并且隐藏了钢捆绑被建议。这新砍墙是一两倍合成砍墙;第一合成是三个不同力量系统的使用, CFT,钢捆绑并且砍墙,并且第二二不同材料,钢和水泥的使用。三 1/5 放大了试验性的标本:传统的 RC 砍墙,有 CFT 列的一面 shear 墙,和有 CFT 列和隐藏的钢的一面 shear 墙捆绑,在周期的装载下面被测试,地震表演 shear 墙索引比较地被分析。从这些实验,彻底的有弹性塑料的有限元素分析和参量的分析基于数据新砍墙用 ABAQUS 被执行软件。在每个阶段的裂缝的变丑,压力分发,和进化的有限元素结果与试验性的结果相比并且显示出好同意。一个机械模型也为计算带负担的能力被建立新合成砍墙。结果显示出那这种新类型砍墙在另外的二种类型上改进了地震性能砍测试的墙。
In order to further improve the seismic performance of RC shear walls, a new composite shear wall with concrete filled steel tube (CFT) columns and concealed steel trusses is proposed. This new shear wall is a double composite shear wall; the first composite being the use of three different force systems, CFT, steel truss and shear wall, and the second the use of two different materials, steel and concrete. Three 1/5 scaled experimental specimens: a traditional RC shear wall, a shear wall with CFT columns, and a shear wall with CFT columns and concealed steel trusses, were tested under cyclic loading and the seismic performance indices of the shear walls were comparatively analyzed. Based on the data from these experiments, a thorough elastic-plastic finite element analysis and parametric analysis of the new shear walls were carried out using ABAQUS software. The finite element results of deformation, stress distribution, and the evolution of cracks in each phase were compared with the experimental results and showed good agreement. A mechanical model was also established for calculating the load-carrying capacity of the new composite shear walls. The results show that this new type of shear wall has improved seismic performance over the other two types of shear wails tested.
