摘要

摘要: 钢筋混凝土密肋剪力墙是一种由混凝土肋梁、肋柱形成网格框架,并在网格内填置轻质材料的一种新型抗震墙体,具有质量轻、抗震性能好、施工方便、造价低等突出优点, 在多/高层住宅、办公楼、地下空间结构等领域具有广阔的应用前景。将该类构件与抗震性能优越且自重轻的钢管混凝土框架结构体系结合,形成钢管混凝土框架-钢筋混凝土密肋剪力墙结构体系,可使得结构体系综合抗震性能更好,且节约施工成本。然而,目前尚无可供设计人员使用的钢管混凝土框架-钢筋混凝土密肋剪力墙结构体系建模方法,制约了该类结构体系的工程应用。为此,开展了2个钢筋混凝土密肋剪力墙在侧向单调荷载下的试验,获得了墙体的侧向力-侧向变形曲线;基于试验结果采用两种等效建模方法进行对比分析,提出了可供设计人员使用的钢筋混凝土密肋剪力墙等效建模方法。基于不同等效建模方法,对比钢管混凝土框架-钢筋混凝土密肋剪力墙结构体系力学性能,探究等效建模方法的选择对体系力学性能的影响。

Abstract: The multi-ribbed composite wall is a new type of seismic wall formed by concrete ribbed beams and ribbed columns, and filled with light weight materials in the grid. It has the advantages of light weight, good seismic performance, convenient construction and low cost; hence, having a promising future in multi-level buildings. The concrete-filled steel tube frame-multi-ribbed reinforced concrete shear wall structure system is formed by combining multi-ribbed composite walls with the concrete-filled steel tube frame structure system, which makes the seismic performance of the structure system better and saves the construction cost. However, there is no modeling method for concrete-filled steel tube frame-reinforced concrete multi-ribbed shear wall structure system for designers, which restricts the practical application of this kind of structure system. Because of this, the experiments on two multi-ribbed composite walls under lateral monotonic loading were carried out. The force-lateral deformation curves of the walls were obtained. Based on the test results, two equivalent modeling methods were compared, and an equivalent modeling method for multi-ribbed composite wall was proposed. Based on the equivalent modeling method, the comparative studies were conducted for concrete-filled steel tube frame-multi-ribbed composite wall structure system with different methods. The effects of the equivalent modeling method on the mechanical properties were investigated.
