1.0 BACKGROUND OF STUDY The deflections of a beam are an engineering concern as they can create an unstable structure if they are large. People don’t want to work in a building in which the floor beams deflect an excessive amount‚ even though it may be in no danger of failing. Consequently‚ limits are often placed upon the allowable deflections of a beam‚ as well as upon the stresses. When loads are applied to a beam their originally straight axes become curved. Displacements from the initial axes

Summary The primary goal of the experiment was to determine the structural stiffness of two cantilevered beams composed of steel and aluminum while maintaining both beams at a constant thickness and cross sectional area. The experiment also investigated material properties and dimensions and their relationship to structural stiffness. The experiment was divided into two separate parts. The results for the first part of the experiment were obtained by clamping the beam at one end while applying different

Slope deflection method From Wikipedia‚ the free encyclopedia The slope deflection method is a structural analysis method for beams and frames introduced in 1914 by George A. Maney.[1] The slope deflection method was widely used for more than a decade until the moment distribution method was developed.

Kanstantsin Varennikau Adrien Francois 04/13/15 Deflection of Beams and Cantilevers (Lab 3) Objectives: In the first experiment‚ our objective was to examine the deflection of a cantilever that had an increasing point load. In the second experiment‚ our objective was to examine the deflection of simple supported beam that had an increasing point load. Experimental Setup: During the experiment we will be using a Test Frame machine to calculate the deflection of a cantilever. We used three different materials to see the varying deflections
