Design and Analysis of Perforated “I” Section Beam

Abstract

The main aim of perforated beam is to increase the depth of the section so it will automatically increase the moment of inertia. A perforated beam is a type of I section beam which is longitudinal cut along its web post and it is divided in two parts and rejoin. The perforated beam is having only three shapes which is Circular, Hexagonal, Square shape and We are generating a new shape which is Pentalpha, Monogram, Pinnacle, Pixshark. We have to increase a depth of the section without increasing the weight of beam. Stress concentration occurs near the perforation and the shearing capacity is reduced, then we have to reduced stress by forming a perforation near the neutral axis then the stresses are negligible.
