摘要：

Two I-shaped precast concrete shear wall specimens with vertical and horizontal joints as well as two reference cast-in-place concrete specimens were prefabricated and tested under low-cycle reversed horizontal forces and different axial load ratios of 0. 1 and 0. 15. As for precast specimen, the horizontal joints were connected by rebars grouted in the metal bellows and the vertical joints were connected by part cast-in-place concrete settled at the web toe within 300 mm. The experimental results showed that precast specimens could obtain emulative aseismic performance to cast-in-place specimen. FEA models were built by ABAQUS and different detailing of part cast-in-place connections were involved. And the lateral rebars connecting precast concrete and cast-in-place concrete were analyzed in the aspect of stress. Based on the FEA results, the suggestions on the part cast-in-place connection detailing and lateral connection rebar configurations were proposed to get more efficient for practical engineering. © 2019, Engineering Mechanics Press.
