ELASTO-PLASTIC ANALYSIS OF UNIFORM GRILLAGES UNDER LATERAL LOAD

A method is presented for analyzing elastic-plastic grillages under arbitrary loads by finite difference calculus. The torsional stiffness of the beams is neglected. The introduction of two discontinuity functions representing the rotation at the plastic hinges permits a complete description of the structure from initial loading until collapse. The development of a collapse mechanism is signified by the vanishing of the determinant of the matrix of the equations determining the amount of rotation of the plastic hinges.
