Title: Analysis of Beam-and-Girder Framing with Known Column Settlements

Abstract:Systematic tabulation of data and the development of relatively simple criteria for checking the equilibrium of joints between columns make analysis by successive approximations entirely practical. Moment distribution tabulations are laid out on a plan view of the framing. Separate, but similar, tabulations are used for moments about the x-x and y-y axes. Beam-and-girder intersections are treated as joints whose elevations are first estimated. Fixed-end moments due to joint defiections are balanced; then summations of vertical forces (shears) at the joints indicate the corrections needed to move nearer equilibrium.
