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.
