Analysis of pre-stressed concrete beam with three circular openings at specific distance from both end of the beam

The purpose of this study is to analyse the flexural and ultimate bending moment of prestressed concrete beam with openings. There are various types of openings on concrete beam but the focus here on circular openings. The major objectives of this study are to determine the modes of failure of pre-stressed concrete beam with circular web openings and to determine the ultimate strength and deflection Of pre-stressed concrete beam. The thesis identifies that if construction of the concrete beam with web openings are not designed wisely, will lower the strength of beam and may collapsed. It further outlines the efficient method taken to overcome this problem. The method used is by operating the ANSYS software. Comparisons are made between the software generated graphical results and results from doing manual calculation. It is proved that the values obtained are similar and that it is an effective and faster way to calculate and get results using the finite element software.
