Abstract
T
his
research presents the reliability of reinforced
concrete beam with embedded PVC pipes below the neutral axis.
First Order Reliability Method (FORM) and the the
ory of
Statistics are reviewed and adopted for designing the beam to a
pre
-
determined safety level using a FORTRAN subroutine
created and linked with the reliability software (FORM5).
Experimental investigation of beams
without PVC pipe (RCBM)
and beams
wi
th one (RCPVC1), two (RCPVC2) and three
(RCPVC3) PVC pipes
were
carried out using ASTMC 293.
Results indicate
satisfactory
performance of
RCPVC1 and
RCBM with similar ultimate failure load.
Other beams have
reduced failure load.
