This paper describes the multilayer and high-rise structure of the precast prestressed shear wall, we made one shape T shape and linked limb shear wall specimens as the objects, we also made comparision with cast-in-place shear wall, the specimens were tested under high frequency and reciprocating horizontal load. And it is analyzed in yield load, bearing capacity, stiffness degradation, energy dissipation as well as ductility conditions by test data. The result shows that Wall’s damage concentrated in roots near the connection, where is the weak area of the precast prestressed concrete straight shear wall, and the wall show characteristic bending failure. |
