Abstract

The Reliability Analysis of a Prestressed Concrete Beam (PCB) was presented using First Order Reliability Method and Euro code 2 procedures to carry out the analysis. The results show that the safety of the PCB in bending decreased from 2.9 to 1.0 and 3.1 to 2.6 as prestress force and the depth from the extreme compressive fiber to the neutral axis of the beam increased from 20kN to 100kN and 150mm to 350mm respectively, therefore the PCB is safer at low prestress force and depth to the bottom layer of the beam. Also, the target safety indices considering bending criteria of the prestressed beam was obtained to be 2.01
