Free Essay About Structural Engineering: Checking The Uniformity Of The Uniformly Distributed Load

Uniformly distributed load (UDL) was analyzed for simply supported beam by developing three scenarios in order to ascertain uniformity in this report. It comprised of three chapters in which UDL was converted into one point, two points and three point loads that were applied on the beam having 5 m length under varying condition. In chapter-1, one point load was applied on the beam having value of 0.5 KN/m. The maximum bending moment of UDL and under one point load was found to be 0.47 and 0.38 KN-m respectively. Secondly in chapter 2, UDL was converted into two point loads that were applied with three situations including equal and symmetrical; equal and unsymmetrical followed by two unequal and unsymmetrical point loads placed on the beam. In the last chapter 3, three scenarios were developed including three equal and symmetrical; three equal and unsymmetrical followed by three unequal and unsymmetrical point loads placed on the beam. Due to unavailability of sufficient data in all scenarios, excel spread sheet was used to generate sufficient data to plot the graphs for bending moment. At the time of one point load, 50 segments were generated. While in case of two and three point loads under each scenario, about 200 and 350 points were generated respectively for bending moment as well as percentile change in bending moment. The beams showed varied stress behavior under various diversified load conditions that consequently result into varying bending moment .This practice generated well defined graphs with linear curves under all conditions that facilitate to evaluate the uniformity of the beam. Maximum bending moment was observed above the neutral axis, and comparatively less percentage was observed below the neutral axis. In addition, this methodology showed that the change in bending moment is associated with placement of point loads instead of distribution of point loads. The stresses developed in the beam and generated graphs revealed that the beam showed uniform behavior under all scenarios.
