摘要：
In order to study the prefabricated shear wall with concrete filled steel tube and vertical patchwork, two 1∶3 scaled prefabricated two-story shear wall with concrete filled steel tube and vertical patchwork were designed and produced. The cross-sections of shear wall were L-shaped and I-shaped. Through the low cyclic loading experiment, the process of the development of cracks and failure modes were studied. Comparing with the straight wall specimen with vertical patchwork, the hysteresis curve, skeleton curve, ductility index, stiffness degradation curve and vertical slip displacement of vertical patchwork were all analyzed. The experimental results show that the steel tube joint connected by sleeve grouting method can meet the requirements of the force, the connection of vertical patchwork is reliable and it can fully meet the requirements of the overall load transfer. Besides, comparing with the straight wall specimens, L-shaped and I-shaped walls has increased the ductility index of structures by 24.44% and 50.38%, and the load carrying capacity by 8.94% and 26.81%. © 2017, Editorial Office of Journal of Building Structures.
