The purpose of this study is to investigate the flexural
behavior of reinforced concrete beams with welded wire fabric as
shear reinforcement under cyclic loading. Atotal of fourteen
beam specimens were made. Twelve contained welded wire fabric
as shear reinforcement while the other two contained
conventional shear reinforcement. The parameters included
concrete strength, shear span to depth ratio, spacing of shear
reinforcement, ratio of positive steel to negative steel, amount
oftension reinforcement and loading history。
The results show that beams with welded wire fabric have
less ductility than beams with conventional shear reinforcement.
Beams with WWF have better crack control than those with
conventional shear reinforcement. Beams with WWF showed
faster deterioration than those with conventional shear
reinforcement in strength and stiffness. Increase of amount of
shear reinforcement and negative steel will increase the energy
dissipation capacity。
