Abstract
This paper presents an experimental study of a
three-story, full-scale precast concrete shear wall structure
in which vertical reinforcing bars in the walls were
spliced by grouted couplers, adjacent precast concrete
panels were connected by vertical segments, and precast
concrete slabs with cast-in-place concrete topping
were used as diaphragms tying vertical members
together. Critical joints, such as horizontal and vertical
wall-to-wall joints, window belly wall connections,
slab-to-wall joints, slab-to-slab joints, and precast
concrete sandwich panel connections, were designed
and verified. Results of a series of pseudodynamic and
quasi-static tests showed that the test model exhibited
excellent seismic performance and failed in the desired
mode. The adopted joints were strong enough to
ensure behavior of the precast concrete shear wall with
grouted coupler systems as if monolithic. The performance
levels and damage states of the test model under
various seismic intensities were evaluated according
to Chinese code GB 50011-2010 and FEMA 356.
Particular attention was placed on the influence of window
belly walls, the performance of precast concrete
sandwich walls, and the performance of superimposed
concrete slabs with different slab-to-wall joints.
