摘　　要：剪力墙结构作为一种常用的多、高层结构体系,随着结构基于性能的抗震设计方法的提出,确定其变形能力也就具有重要意义。本文首先介绍了目前国内外剪力墙变形能力的研究成果与现状,并在此基础上,综合考虑ECC变形能力与普通混凝土变形能力相差较大的特点与现有抗震设计方法的适用性,对塑性铰区采用ECC的剪力墙的变形能力计算方法提出可行思路,并对其变形能力设计方法的发展方向做了合理预测。能够对有关研究人员提供理论指导与借鉴。Shear wal structure is widely used in the multilayer and highrise structure system;it has become more signifycant to determine the deformation capacity of the shear wal structure since the performancebased seismic design method was proposed. The research achievements and the present situation about the deformability of shear wal at home and abroad are introduced in this paper. Considering the significant difference between ECC and concrete in deformability and the applicable scope of the seismic design method in use, a feasible calculation method of the Shear Wal deformability with plastic hinge region using ECC materials is proposed, The development trend of the deformability design method is reasonably forceasted. This paper can provide theoretical guidance and reference for related researchers.
