THE 2-DIMENSIONAL FRAME MODEL OF THE DIFFERENTIAL QUADRATURE ELEMENT METHOD

The author has proposed a differential quadrature element method (DQEM ) for numerically solving continuum mechanics problems. This method em ploys the differential quadrature (DQ) technique to discretize the ele ment-based governing differential or partial differential equations, t he transition conditions on inter-element boundaries and the boundary conditions on domain boundaries. A global algebraic equation system ca n be obtained by assembling all of the discretized equations. A rigoro us solution can be obtained by solving the global algebraic equation s ystem. In this paper, the developed two-dimensional DQEM frame model i s presented. Mathematical formulations are carried out. The procedures of numerical algorithm are summarized. By using this DQEM model, accu rate results of two-dimensional frame problems can be efficiently obta ined. Numerical results demonstrate this DQEM model. Copyright (C) 199 6 Elsevier Science Ltd.
