Experimental Study of Seismic Behavior of Prefabricated Reinforced Concrete Frame with Infill Slit Shear Walls

Abstract

Abstract:

Abstract： In order to study the seismic performance of prefabricated reinforced concrete frame with infill slit shear walls (PRCFW), two half-scale PRCFW models with one bay, two stories were designed to conduct low cyclic load. The failure mechanism and deformation capacity of PRCFW were gained after the analysis of the failure mode, stiffness degradation, ductile behavior and performance of energy dissipation of specimens. Experimental studies show that the castin-situ joint presents good working performance during this experiment, and the seismic design requirement of strong connection-weak bar is satisfied. The PRCFW has good ductility with a ductility factor greater than 3. The failure mode of slit shear walls is changed and developed from the bending failure of shear wall into the shear failure whose shear crack runs through the whole shear wall. Besides, no failure occurs in the connection between the frame and the infill wall. Moreover, the shear connector worked well. The test results can provide useful information for further research and engineering application of PRCFW.
