Determination of the displacements of the conjugated ends of the span structures of bridge structures and recommendations for selecting modern designs of deformation joints

Abstract

The article examines the deformation joints of bridge structures that overlap gaps between span structures and
other parts of the bridge (supports, supports) to ensure smooth and safe traffic flow, designed to compensate for
deformations caused by temperature changes, dynamic loads, and other factors. Also, the types of stresses on
deformation joints, determining the calculated temperature range, and determining the displacements of the ends
of span structures from various types of stresses are described. Recommendations for choosing a deformation
seam are given depending on the calculated values of displacements of the ends of the span structures.
The article also examines determining the installation size of the deformation seam.
