Presents a concise analysis for one-, two- and three-span continuous concrete rigid frame bridges by an adaptation of the slope-deflection method. Several complete numerical solutions for the statically indeterminate moment distribution which results with rigid frame bridges made up of members having a variable moment of inertia are given using this method. An analysis is proposed based on the use of construction joints designed to eliminate the high stresses resulting from temperature changes and rib shortening in the multiple span cases.
