An Equivalent Plate Model With Orthotropic Material Properties For Adjacent Box-Beam Bridge Superstructure, Timothy Alexander Schnell

Masters Theses

Reflective cracking over the longitudinal joints of adjacent box-beam bridges is a welldocumented and recurrent problem; it is a concern because it leads to poor durability performance. These cracks develop during early stages of bridge construction and have not been eliminate by the design revisions implemented so far.

This study is aimed at developing a rational load demand analysis model for calculating the moment acting at the longitudinal joints in order to determine the impact of post-tensioning on mitigating reflective cracking.

The scope of the study includes calculating moment demand at the shear keys using a rational analysis model based …
