Concrete Beam With and Without Openings Using Sisal Fiber

The purpose of this experimental study is to know the behaviour of beam when openings such as pipe holes are made at the compression zone of the RC beam. The pipe hole are made as a passage for electrical wires, water pipeline etc., This can be generally adopted for multi-storey buildings. Usually while providing the openings in the beams, the distance at which the openings to be provided are not considered, at that point that failure loads increases. In this study, the required size and position of openings are considered to reduce the failure of the beam. This study deals with the behaviour and ultimate strength of sisal fiber reinforced concrete (SFRC) deep beams with and without openings in web subjected to two- point loading, four concrete deep beams of dimensions 1500mm×300mm×150mm thickness were tested to destruction by applying gradually increased load. Simply supported conditions were maintained for all the concrete deep beams. The percentage of sisal fiber was varied from 0 to 2.The influence of fiber content in the concrete deep beams has been studied by measuring the deflection of the deep beams and by observing the crack patterns
