ANALYSIS OF ARCH BRIDGE UNDER CERTAIN RATERAL FORCES

Shigeru Kuranishi

Open full text 4 citations

Abstract

In this paper, the author carries out the analysis of two-hinged arch bridge under certain lateral forces, which is composed of two arched main girders and calculates the torsional moment, bending moment and normal stress acting on the arched girders, representing the bridge by a curved beam. The influences of flexural rigidity of cross beams on the torsional rigidity of bridge and the tensile forces produced in the arch shoes are discussed.
