Stiffness Report from laboratory work performed on 12 May 2011 as a part of the unit of study CIVL2201 Structural Mechanics Abstract This report has been written to describe an experiment performed on a channel section examining the stiffness of the beam through two differing types of deformation – curvature and deflection. The aim of the experiment was to determine the value of the flexural rigidity (EI) in two different ways; using the curvature‚ k‚ and the mid-span deflection. The testing method

how the shear forces and bending moments vary along the length of a beam that is being designed. Graphs are used to describe the change of shear forces and moments. These graphs are called shear and moment diagrams. Employing these diagrams‚ the maximum and minimum shear and moment are easily identified and located. Constructing shear and moment diagrams is similar to finding the shear and moment at a particular point on a beam structure. However‚ instead of using an exact location‚ the location

conducted to understand the behaviour of a simple structure with a rectangular cross-section. The test was completed succesfully although some mistakes occured between theoretical and empirical results. The second experiment consited of an unsymmetrical beam‚ of which the determination of its principal axes was made. Then the third experiment‚ shear centre‚ was conducted in order to find the shear centre. Finally‚ all the experiments were completed‚ and the objectives were met‚ even with the presence of

a load of 1.5 tonnes along I-beam of 4 metres long. The research that we did was mainly on existing trolley cranes and the configurations of these cranes which allowed us to familiarize ourselves with what the crane does and how it works. The way that the crane operates is by having a person pull a chain. This chain is connected to a drive shaft which in turn is connected to a pinion and two wheels. These wheels allow the crane to move horizontally along the I-beam whilst sustaining a load.

Figure 2 For the 304 Stainless steel2 beam shown in Figure 2 you are required to: a Calculate the reactions and create the shear force and bending moment diagrams for the beam. Select the lightest weight steel wide-flange beam3 that will safely support the bending load (use a factor of safety‚ FS=2). Do not include the weight of the beam for this calculation. Derive and graph the equation of‚ slope and elastic curve by integration. (Ignore the weight of the beam for this calculation.) Determine the

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.
