Analytical Evaluation of Concrete Bridge Parapet and Structure Mounted Guiderail

摘要

The report presents the results of computer simulation and structural analysis on three concrete parapet designs and one W-beam guiderail design to determine their possible acceptance as bridge railings according to the new AASHTO Guide Specification for Bridge Rails. Conclusions and recommendations are provided. Computer simulations were also performed on the safety shape and F-shape concrete parapets to provide insight about the required height for each shape to keep a tractor trailer upright.
