TABLE 13-2 STATICALLY INDETERMINATE RECTANGULAR FRAMES The directions of the reaction forces are shown in the figures of the configurations. The signs of moments are shown in the moment diagrams. A bending moment is indicated as positive when it causes tension on the inner side of the member and compression on the outer side. Opposing moments are negative. The formulas in the table give the magnitudes of the forces and moments. e = h/L Definitions β = Ih (horizontal beam)/Iv (vertical members) Configuration Moment Diagram Important Values 1.
