Abstract:
Large-panel houses are made by assembling story-high precast wall panels. The vertical joints between the precast wall panels form shearing media that insure interaction between the precast wall panels in the same manner as the spandrel beams in a coupled shearwall. In this paper, the shear carrying capacity and shear stiffness of such vertical joints have been determined based on a series of tests on 29 specimens. Evaluation of shear capacity of joints has been based on both the shear friction hypothesis and Mohr-Coulomb's failure criterion.
