摘要：

To study the seismic behavior of splice rebar connection between the upper and lower floors of shear walls with precast concrete hollow moulds and verify the chosen splice length and compare different styles of the splice rebars, quasi-static tests of four full scale wall specimens and static tests of two full scale wall specimens have been carried out. The test results indicate that all specimens fail in flexural mode. The measured load-carrying capacity of the wall specimens is about 1.31 times as large as the predicted value according to the formula in the current design code. The ultimate drift ratios of the specimens are 1/85-1/55. The bottom horizontal slippage of the wall specimens is negligible. According to the measured strain curves, strain distribution and seismic behavior of the specimens, it is shown that the stress in the distributed reinforcements can be transferred by the splice rebars effectively. The designed splice length can ensure their strength contribution. Seismic behavior of the specimens with two-row splice rebars seems better than that of the specimens with single-row splice rebars slightly. ©, 2015, Science Press. All right reserved.
