Grillage for 6 beam skew bridge

A grillage analysis for a single span bridge comprising 6 main skewed beams supported on pinned or rotational springs using a stiffness matrix (short and long term) based on 3 degrees of freedom at each joint – vertical deflection and 2 rotations. Loading is by joint forces or moments in 2 directions. Optional support conditions allow integral bridge decks and ‘ladder’ type bridges (2 main beams) to be analysed. A separate differential settlement analysis is included for integral bridges. The global axis may be rotated to facilitate the input of rotational springs parallel and at right angles to the abutment.
