• Abstract:
  An efficient numerical method of solution to structural frame problems is presented. The method is shown to be applicable to no-sway, plane-frame structures that may derive part or all of their support from soils. A finite-element model composed of bars and springs is used to represent groups of orthogonal frame members. Finite difference equations written for this model are solved by a previously developed recursive method. Individual beams are solved alternately in the two orthogonal directions and at each joint a relaxation technique is used to adjust the two solutions and achieve rotational compatibility. A complete listing of the Fortran computer program is included, plus several example problems illustrating the applicability of the method.
