ECC剪力墙抗震性能研究进展

Research progress on seismic performance of ECC shear wall

由于受到钢筋、混凝土材料本身特性的限制,传统剪力墙在地震作用下凸显出低延性、裂缝数量多、碎块易脱落等问题。本文归纳总结了纤维水泥基复合材料(Engineered Cementitious Composites,以下简称“ECC”)等高延性材料应用于不同类型剪力墙的研究进展,得到了ECC材料应用于剪力墙可以提升抗震性能,克服了传统材料诸多缺点的结论,并展望了ECC剪力墙的发展方向。

Due to the limitation of the characteristics of steel and concrete materials, the traditional shear wall under the action of earthquake highlights the problems of low ductility, large number of cracks, fragments easy to fall off and so on. In this paper, the research progress of the application of high ductility materials such as Engineered Cementitious Composites(ECC)in different types of shear walls is summarized, and the conclusion that the application of ECC in shear walls improves the seismic performance is obtained and many shortcomings of traditional materials are overcome, then the development direction of ECC shear walls is prospected.
