| Summary: | This dissertation presents an experimental study related to the tensile force and
bond stress of longitudinal reinforcement in heavily reinforced concrete beam. The test
variables in this study include the ratio of longitudinal and shear reinforcement. The
beam specimens are simply supported with two point load with 130mm wide, 230mm
deep and 1800mm long. The tensile force behavior and bond stress of longitudinal
reinforcement is observed at support region. From experimental and analytical analysis,
all beam specimens are not encounter failure in bond at support region. The beam with
higher longitudinal and shear reinforcement ratio experienced lower bond stress
compared to the lower longitudinal and shear reinforcement ratio. Besides that, the tensile
force at the support is increased significantly after the occurrence of the diagonal cracks.
As the reinforcement in the middle beam yield, the tensile force at the support stops
increasing. Additionally, a computer program developed to determine the bond stress-slip
curve at the support zone by applying Second Order Runge-Kutta method. Bond stress
along longitudinal reinforcement beyond the outer part of the support also examined
theoretically using local bond stress-slip model that modified from CEB-FIP Model Code
1990. |
