Low Cyclic Loading

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.

New Type

The shear wall built with precast two-way hollow slab is an innovated precast concrete shear wall suitable for housing industrialization. Two shear walls built with precast two-way hollow slabs were tested pseudo-statically under low cyclic lateral loads to acquire their failure process and modes. The effect of the axial compression load was investigated. The study proved that vertical cracks along the vertical holes of the new type shear wall have been appeared to avoid brittle shear failure, and the shear wall developed integral section wall to walls-columns combination. As the results, the shear walls have the adequate deformability. The test results showed that with the increase of axial compressive ratio, crack development has been limited and the energy dissipation capacity has been improved. It also can be found that with the increase of the axial compressive load, shear capacity of the new type shear walls have been improved.

Axial Compressive Load

Low-cycle cyclic loading tests were carried out on seven reinforced concrete shear wall specimens with different design parameters to investigate the damage behavior under earthquakes. The damage features including the damage process, deformations, the maximum crack width and the corresponding residue crack width at different damage state were recorded. According to the experimental data, the influence of axial compressive load ratio, stirrup ratio of the boundary column and cross-section shape on the ductility, carrying capacity, deformation characteristic and seismic damage is analyzed. With the axial compressive load ratio increasing, the carrying capacity and shear effect increase while the ductility and residual crack ratio decrease. With the deformation and damage increasing, the shear effect increases. The shear walls with I-shaped cross-section display more shear effect than those with the cross-section of “—” and “T” shape.
