ABSRACT - [ Total Page(s): 1 ]The Reliability Analysis of a Prestressed Concrete Beam (PCB) was presented using First Order Reliability Method and Eurocode 2 procedures to carry out the analysis. The results show that the safety of the PCBin bending decreasedfrom 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. The safety of the PCB increased from 1.52 to 2.5, 1.52 to 2.5 and 0.1 to 2.0 respecti

CHAPTER ONE - [ Total Page(s): 2 ]The development of structural reliability methods during the last three to four decades have provided a more rational basis for the design of structures in the sense that the method facilitate a consistent basis of comparison between the reliability of a well-tested structural design and the reliability of new types of structures. For this reason the methods of structural reliability have been applied increasingly in connection with the development of new design codes (Sorenson et,al., 2002). In recent years design codes have been continuously revised to include limit states ... Continue Reading
