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. Reliability analysis usi ng FORM5 revealed area of reinforcement 38.9% higher than deterministic design for RCBM and RCPVC1 beam with safety index, β=3 .3 - 4 .4 meeting the probabilistic code’s requirement and same area of reinforcement for RCPVC2 and RCPVC3 using deterministic desi gn . It is concluded that the method is suitable for application.
