Abstract:An efficient numerical method of bending analysis for simply connected grid-over-beam and orthotropic plate-over-beam layered structural systems is presented. The method relies upon the availability of a high-speed digital computer. In the method, the real structure is replaced by a finite-element model of bars and springs. The equations for the two types of systems considered then are derived directly from the model to circumvent conventional assumptions of continuity. The model elements are further grouped into individual beams or line members for the three-phase iteration process. An alternating direction relaxation technique is employed to coordinate the solution of the individual beams.
