A HIGHER ORDER INPLANE PARALLELOGRAM ELEMENT AND ITS APPLICATION TO SKEWED CURVED BOX-GIRDER BRIDGES
THE INPLANE STIFFNESS FOR A PARALLELOGRAM ELEMENT IS DERIVED FOR NODAL PARAMETERS U, V AND THETA BY ASSUMING LINEAR DISPLACEMENT FUNCTIONS FOR U AND LINEAR AND CUBIC DISPLACEMENTS FOR V ALONG THE TWO SETS OF PARALLEL SIDES OF A PARALLELOGRAM. THIS ELEMENT GIVES GOOD ACCURACY WITH EVEN COARSE MESH FOR THE ANALYSIS OF BEAMS, WHEN THE CUBIC VARIATION OF V CORRESPONDS TO THE VERTICAL DEFLECTION. A PARALLELOGRAM SHELL ELEMENT IS ALSO DERIVED SIMPLY BY COMBINING AN IN-PLANE AND A PLATE BENDING STIFFNESS. A STRAIGHT BOX-GIRDER BRIDGE AND A CURVED BOX-GIRDER BRIDGE ON SKEW SUPPORTS ARE ANALYSED AND THE RESULTS ARE COMPARED WITH THOSE OBTAINED EXPERIMENTALLY AND BY LOWER ORDER ELEMENTS. /AUTHOR/
