Q1. Mesh Convergence study Using the FEM Software LUSAS, build the following model of a concrete beam with a Global Distributed Load. Use the FEM Software to estimate the value of the displacement at the midspan of the beam. By confronting the FEM results with the analytical solution for the considered case, check the effect of the number of mesh elements on the final solution. !!!!!!!!!!!!!! q= 50 kN/m L= 8m Beam Cross Section and Materials Details h=700mm Concrete: Europe -EN 1992-1-1:2004/2014 C30/37 b=300mm a. Estimate the analytical solution for the considered case. (Please use the material properties according to LUSAS Database). b. Starting from a number of mesh elements equal to 2, build a convergence graph to show the number of elements necessary to reach the convergence to the real solution of the problem. (Increase the number of elements of 2 for each iteration, i.e. 2,4,6 and so on). C. Comment on the number of elements that you would consider acceptable for this model. Q1.
