Shear-Vulnerability of Existing Pre-Stressed Concrete Bridges Part One: Basics

Shear-Vulnerability of Existing Pre-Stressed Concrete Bridges Part One: Basics In Part I to formulate an operation directive the revised load assumptions for bridges of DIN Technical Report 101 are compared with the loading classes according to old standards and it is demonstrated, how the loading models can be modified based on actual traffic data, The current bridge asset in the Federal State of Hesse is evaluated using the Road Information Database (Sub-Project: Structural Data) in order to work out classification and evaluation criteria. Regarding the assessment of the shear load-bearing capacity the fundamentals of the shear load design models of DIN 1045, DIN 4227, DIN TR 102 and from the literature are compared.
