Traditional composite shear walls consist of a plate with a concrete wall on one or both sides of the steel plate and boundary columns and beams. By properly combining the advantages of the reinforced concrete and steel plate shear walls, and by eliminating or reducing their disadvantages, and efficient composite shear wall system can result such as innovative version of the composite shear wall systems, had great potential to become a very efficient and high performance lateral lead resisting system. This project will study and develop seismic design recommendations for the wall systems. The following interrelated analytical and experimental investigations will be conducted.Inelastic finite element parametric studies of the traditional composite shear walls and the new system,Parametric inelastic time-history analyses of the global and local seismic responses of structures with both types of shear wallsCyclic tests of four two-story specimens representing composite shear wall systems,Developing seismic design recommendations for composite shear wall systems,Finally, after design recommendations have been formulated, the recommendations will be applied to design of at least two structures with composite shear walls. Then, inelastic time history response analysis of the structures will be conducted to verify desirable performance of the structures. .This

传统的组合剪力墙由钢板一侧或两侧的混凝土墙和边界柱和梁组成。通过适当地结合钢筋混凝土和钢板剪力墙的优点，并通过消除或减少它们的缺点，可以产生高效的组合剪力墙体系，如创新版的组合剪力墙体系，有很大的潜力成为一种非常高效和高性能的抗侧导体系。该项目将研究和开发墙体系统的抗震设计建议。将进行以下相关的分析和实验调查。传统组合剪力墙和新体系的非弹性有限元参数化研究，两种类型剪力墙结构整体和局部地震响应的参数化非弹性时程分析，代表组合剪力墙体系的四个两层试件的循环试验，制定组合剪力墙体系的抗震设计建议，最后，在制定设计建议之后，这些建议将应用于至少两个复合剪力墙结构的设计。然后，对结构进行非弹性时程响应分析，验证结构的良好性能。这
