Determining maximum beam deflection under different conditions of loading

Beams are usually long, straight prismatic members. Steel and aluminum beams play an important part in both structural and mechanical engineering. In most cases, such as diggings in sea and land for extraction of petroleum, the loads are perpendicular to the axis of the beam. One of the task works of the design engineer is to predict arrangements and proportions of Members that can withstand economically and efficiently for the conditions anticipated during the lifetime of a structure. A central aspect to this structure is the calculation of the beam deformation, which has very wide applications in structural engineering. In this paper a semiexact analytical method is shown and the applicability and effectiveness ofthat, is shown for solution of nonlinear problems. This method applied to Solution Of beam deformation Equation for two beams with two fixed ends, under linear distributed load and under concentrated load then the results are compared with exact solutions. This technique that is used in this work has this capability to find closed-form solutions of nonlinearproblems and this method is easier to use and will be save in time.
