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 integra...
