The numerical methods such as Finite Element Method (FEM) are used for the linear and nonlinear analysis of the structures. Alternatively, Applied Element Method (AEM), which is recently developed displacement-based method can be effectively adopted for tracking the structural collapse behavior during all stages of analysis i.e. from zero loading to complete collapse. In AEM, structure or structural members are discretized with rigid elements connected by springs in which the deformation characteristics of the structure are represented by normal and shear springs connected between the faces of rigid elements. In the present study, application of AEM is illustrated through the static linear analysis of reinforced concrete simply supported beam considering it as a two-dimensional (2D) problem. The analysis results in terms of displacement and stresses are compared by considering the different number of springs and variation in size of an element. It has been observed that smaller size of an element with a smaller number of springs gives accurate results. To show the accuracy and applicability of method, results obtained by AEM are compared with the FEM results. |
