Abstract:In order to study the seismic performance of cast-in-place reinforced concrete shear walls with wedge-shaped joints, the full-scale quasi-static tests of the prefabricated reinforced concrete shear wall specimens with shear span ratio of 2-1 were carried out and results were compared with those of cast-in-situ shear wall specimens with the same size. The experimental results show that the failure modes of the prefabricated wall specimen and the cast-in-place wall specimen are basically the same, featuring the yield failure of vertical steel bar and compression failure of the concrete at the bottom of the wall. The ultimate displacement angle of the prefabricated wall specimen is 1/69, which is slightly smaller than that of cast-in-situ wall specimen. And the crack loading and the bearing capacity are smaller than those of the cast-in-place wall. The hysteresis curve of the prefabricated wall specimen is full and its ductility satisfies the seismic requirement. The finite element analysis software ABAQUS was used to conduct numerical simulation on prefabricated RC shear wall with cast-in-place wedge-shaped joint connection. The bearing capacity and lateral displacement obtained from the simulation were similar to the experimental results. The skeleton curves obtained by the two methods were also consistent.

Keywords:wedge-shaped connection; prefabricated reinforced  concrete shear wall； seismic performance; finite element analysis
