• Abstract:
  A discrete-element method of analysis for anisotropic skew-plate and grid beam systems is presented. The method can be used to solve a wide variety of problems. The principal features are (1) formulation of six elastic stiffnesses and compliances in terms of three moduli of elasticity in any three directions and three Poisson's ratios related to these directions, (2) representation of an anisotropic skew-plate and grid system by a discrete-element model consisting of a tri-directional arrangement of rigid bars and elastic joints, (3) formulation of stress-strain and moment-curvature relations for the discrete-element model using concepts of a continuum composed of interconnected fibers, (4) derivation of a stiffness matrix using equations of statics, and (5) a recursion-inversion procedure to solve the stiffness equations.
