| Abstract | Experimental data from the previous study [9] are analyzed
to investigate the shear strength of prestressed concrete linear
members without shear reinforcement. Analytical approach of
investigating the behavior in shear of prestressed concrete beams
without shear reinforcement is conducted using a finite element
method where analytical mode ling for the concrete, steel
reinforcement, bond between the concrete and the reinforcement,
and stress transfer along crack are considered to be a plane
stress problem. Several examples of singly reinforced concrete
beams on simple supports with different effective restressing
force and different diagonal cracking patterns are analyzed and
results are presented for comparison and discussion. Shear crack
is modeled as a single discrete crack a nd other cracks are
modeled as smeared cracks. Forces transferred along the diagonal
cracks are determined by applying models for both aggregate
interlocking and tension softening of concrete. A non
bond s lip model is also implemented.
The depth of compression zone increases for beams
increases in restressing force, which is considered to
linear
with
be a
reason of increase in beams. Opening and sliding displacements at
shear crack are affected greatly by mode l s for stress transfer at
crack a nd bond-slip, but the ultimate shear strength are not .
Idealized shear crack pattern for discrete crack mode ling can
change the ultimate shear strength when its location in
longitudinal direction changes, but not when its location in
vertical direction changes . |
