This program performs a stiffness analysis of right, single and multiple span T-Beam and box-structure bridge decks (under the action of user-specified loading) to calculate in-plane forces in slabs, bending moments in slabs, flexural shear forces normal to slabs, normal deflection in slabs, axial force in beams, bending moments in beams, shears in beams, displacements in beams, stresses in beams, reactions at supports of multiple-span structure. This output may be obtained both in tabular form on the line printer or as graphical plots on digital plotter. Influence lines for a single load or a user-specified vehicle may be obtained and automatically plotted for most of the output variables listed. The program can analyse bridge decks with up to 18 beams, 17 upper slabs and 17 lower slabs. The slabs may be of different widths and thicknesses and have non-zero slopes; the beams also may have non-zero slopes. The program can only analyse structures which are simply supported at each end. /TRRL/
