Abstract
The paper presents a method of analyzing symmetrical continuous I-Beam bridges based on fun.ctions defining influe.nce diagrams for moment .and shear. 'I'hese functions are derived from an .application of the -Conjugate Beam principle to MullerBreslau's principle, and have been used for several years by the -Iowa State Highway Commission. The method has been programmed for the analysis of 2, 3, 4,.and 5 span symmetrical bridges, thereby_ increasing its usefulness. The computer ·program is divided into three sections. Section 1 computes the values of the influence lines, the maximum moments at the piers and in the spans, the stresses at the points of maximum moment, the lengths of cover plates, and the point of zero moment for dead load. Section 2 computes the deflection. at the quarter points between splices. Section 3 computes the reactions and shears.
