Experimental study on mechanical behaviors of new shear walls built with precast concrete hollow moulds

To study mechanical behaviors of shear walls built with precast two-way hollow slabs, two shear walls with different details of hollow slabs were quasi-statically tested under low cyclic loading. The failure mode was analyzed, which vertical macro-cracks appeared on walls due to the details of hollow slabs. Brittle shear failure can be avoided in terms of the failure behaviors evolved from integral wall to the combination of wall and columns. Test results also show that that dimension of transverse holes can affect compressive capacity of the walls when it is larger than that of longitudinal holes in the hollow slab.

Precast two-way hollow slab concrete shear wall is a new structure adapted to housing industrialization. To study the effect of the vertical joint on mechanical behaviors of shear walls, one reinforced concrete shear wall and two precast concrete shear walls built with hollow slabs were quasi-statically tested under low cyclic loading. The study of failure mode and failure process of specimens shows that vertical macro-cracks occurred in precast walls under loading, which made failure behavior of walls evolve from integral wall into split wall. It also shows that relative deformation formed along the vertical joint before peak load, so the ductility of walls is increased. New type shear walls exhibit good ductility and brittle shear failure can be avoided effectively.

Background: To study the flexural behaviors of the concrete shear walls with precast hollow slab, one cast in-situ reinforced concrete shear wall and two precast two-way hollow slab shear walls (PTHSWs) vertical joint were tested under low cyclic loading. Objective: The study showed that vertical joints of PTHSW are safe and reliable to ensure the effective connection between the assembly units. The ductility coefficient of shear wall is larger than 7, so this kind of shear wall has good ability of deformation especially under earthquake load. Results: The interface can effectively ensure the integral performance of PTHSWs and its effect on the flexural behaviors of PTHSWs could be ignored.
