摘　　要：目前,联肢剪力墙结构普遍存在于我国高层建筑中,而混合联肢剪力墙结构作为其中的一种,能够充分利用混凝土和钢材的优势,其延性耗能能力以及抗剪能力更强.但由于墙肢较大的延性导致其设计方法和抗震性能的复杂化,混合联肢剪力墙结构并未广泛应用于工程实践中.因此,对混合联肢剪力墙结构进行设计方法和抗震性能的研究具有重要意义.本文采用了与传统方法不同的能量平衡塑性设计方法,该方法综合考虑了结构的力、变形以及耗能等因素,并且可以预先控制结构的变形大小和屈服机制.本文基于该设计方法设计了12个混合联肢剪力墙结构算例,并在有限元软件中对其进行了推覆分析,得到了12个算例的相应推覆曲线.结果表明,12个算例能够实现理想屈服机制,保证在结构破坏时连梁最先达到屈服、墙肢后屈服,从结构承载力的角度看,结构也能满足较高的抗震要求.At present,the joint shear wall structure is common in high-rise buildings in China,and the hybrid limb shear wall structure is one of them.It can make full use of the respective advantages of concrete and steel,and has great ductility and can meet larger shear demand.However,due to the large ductility of the wall limbs,the design method and seismic performance are complicated.The hybrid limb shear wall structure is not widely used in engineering practice.Therefore,it is of great significance to study the design method and seismic performance of the hybrid limb shear wall structure.In this paper,an energy balance plastic design method different from the traditional method is adopted.The method comprehensively considers the force,deformation and energy consumption of the structure,and can pre-control the yield mechanism and deformation size of the structure.This paper based on energy balance plastic design method.12 hybrid coupled shear wall examples are designed and static Push-over analysis is carried out in finite element software.The static pushover curves of 12 examples are obtained.The results show that 12 examples can realize the ideal yielding mechanism,and ensure that the joint beam first yields and the wall is yielded after the structural failure.From the per-spective of structural bearing capacity,the structure can also meet the higher seismic requirements.
