摘要
钢板外包混凝土预制装配式剪力墙板是在钢板剪力墙板基础上提出的一种用于高层建筑钢结构的新型抗侧力构件。它以普通钢板作为基本支撑板，钢板上、下分别与钢框架中的梁相连，两侧外包混凝土为钢板提供侧向约束，防止钢板过早屈曲失稳，同时混凝土还起到防火隔热的作用。本文通过对３个钢板外包混凝土剪力墙试件和１个纯钢板剪力墙板试件的模型试验，研究了在低周反复加载下钢板外包混凝土剪力墙板的破坏形态、延性、抗剪强度和刚度等。试验表明，钢板外包混凝土剪力墙与钢板剪力墙相比，具有良好的稳定性能和延性性能，同时其刚度和强度也大大提高。
The concrete-incased steel plate shear wall is a new kind of bracing used in tall steel building.The steel plate incased in the concrete plays the main role to resist the lateral forces, while the concrete supplies lateral restraint to steel plate to enhance the lateral stability of the steel plate and hence increases the capacity of the concrete-incased steel plate shear wall for resisting lateral forces. Three tests of concrete-incased steel plate shear walls and one test of steel plate shear ball have been conducted by the authors and their failure modes, ductility, shear strength and stiffnes have ho also studied under low frequency cyclic loading. Experimental investigations show that the concrete-incased steel plate shear wall has good stability and ductility behavior and its stiffness and strength are improved in comparison with the steel plate shear wall.
