These gridworks are found in practice in bridge and roof structures; equations presented were derived to solve problem of prestressed concrete deck, 177 by 177 ft, with beams spaced 10.8 ft apart in each direction and supported by eight columns located in perimeter of deck; equations have been derived by slope-deflection-gyration method, where torsional stiffness as well as flexure stiffness of gridwork bars are taken into account.
