Abstract
The ordinary U-stirrups have always been
used especially in beams as web reinforcement
in most modern construction. As a probable
substitute, here wire wesh of 3mm diameter is used
to reinforce beams in shear. The investigation
thus involves testing of beams reinforced in shear
separately with the ordinary U-stirrups and with
wire mesh. The beams are all the same with the
only difference being in the web reinforcement.
Apart from the mesh being easier to fabricate,
the analysis of the results obtained shows that
beam with the ordinary U-stirrups recorded more
strains in the concrete than those with wire mesh.
Moreover, crack control is better in the beams
with mesh as their formation and propagation was
more gradual leading to a gradual failure of the
beams. However, it is recommended that a basic
formular for calculating the theoritical shear
resistance of beams involving mesh be deviced to
include the influence of the horizontal members
of the mesh on the shear resistance.
