Analysis and Design of Arch-Type Pedestrian Bridge for Static and Dynamic Loads

Abstract

A major obstacle for pedestrians south of the Indiana-Purdue University Fort Wayne (IPFW) campus is Coliseum Boulevard: a main arterial for the city of Fort Wayne, Indiana, which has an average daily traffic (ADT) of 50,000 vehicles. With this high ADT value, crossing by foot can not only be challenging, but can be dangerous. Thus, a pedestrian bridge over Coliseum Boulevard was proposed to allow for easy, safe travel over this busy roadway. Cohering to the innovative design concepts of both the Willis Family Bridge and the Venderly Family Bridge that already exist on the IPFW campus, the new bridge should be designed so that it too can be transformed into a landmark for the IPFW campus as the other two bridges have become. This paper presents the conceptual design of the pedestrian bridge considering four potential bridge concepts as well as the modeling, analysis and design details for the selected arch type pedestrian bridge. The selected concept for the pedestrian bridge was analyzed and designed using SAP2000 for static dead and live loads as well as for the wind loads according to AASHTO specifications and INDOT requirements. The same ideas could be drawn to Abdalli New Area in Jordan where innovative designs brings pleasure and comfort to residence and shoppers in the area.
