A series of eight full-size reinforced concrete specimens were tested
subject to different ratios of in-plane to bending loadings. The prima
ry goal of the tests was to examine the influence of the bond between
concrete and reinforcement on the amount of tension carried by cracked
concrete. The parameters in the test program included reinforcing bar
diameter, ratio of in-plane to bending loadings, reinforcement ratio,
and concrete cover. The test results showed that different longitudin
al reinforcement configurations, for the same reinforcement ratio and
the same loading and boundary conditions, result in different cracking
loads and different post-cracking stiffness of the reinforced concret
e beams.
