EXPERIMENTAL-AND-THEORETICAL STUDY OF THE STRESS-STRAIN STATE OF THE FERRONCONCRETE ARCH UNDER HIGHWAY BRIDGE

Abstract

Described are procedures and results of investigating the stress- strained state (SSS) of the filled in with soil bridge construction with a cylindrical arch of a constant thickness made from the monolithic reinforced concrete with the use of flat and three-dimensional finite-element models. The data of the full-scale measurements of displacements and deformations of the bridge span are compared with the results of calculation on the basis of the models accepted.
