Abstract：Aiming at the seismic behavior of precast shear wall connected with straight thread grouting sleeves, the quasi-static tests for two full scaled precast specimens and a cast-in-place specimen were carried out, and the vertical reinforcements of precast specimens were connected with straight thread grouting sleeves.The results indicate that the straight thread grouting sleeves can transfer the reinforcement stress and make the reinforcements connected with the sleeves work coordinately.All three specimens belong to bending failure, but the failure forms are different.The horizontal cracks form in the post-poured connection of precast specimens.In addition, the deformability, stiffness and energy dissipation capacity of precast specimens are similar to those of cast-in-place specimen.When the position of horizontal connection moves up, the deformability of specimens gets improved to some extent.With the current specifications, the bending bearing capacity of precast shear wall can be calculated.Under the low cycle loading, the mechanical properties of precast specimens connected with straight thread grouting sleeves are similar to those of cast-in-place specimen.
