Abstract

To evaluate the seismic performance of pre-cast concrete shear wall with vertical reinforcements spliced by two different grout ways, quasi-static tests of two concrete shear walls holed by prefabricated corrugated pipe and one concrete shear wall holed by drawing out the pipe were tested. The test results showed that the wall holed by prefabricated corrugated pipe was basically the same as the wall holed by drawing out the pipe in failure modes. The hysteretic curves of the specimens are full, the trend of the skeleton curve is basically the same and the capacity of the energy dissipation is close. The displacement ductility factors are more than 4. For the two walls holed by prefabricated corrugated pipe, when the lap length is reduced, the seismic performance decline as well, but the wall still meets the current seismic code requirements.

Keywords: Pre-cast shear wall, restraint anchor, the way of hole, seismic behavior, quasi-static test.
