Abstract:

A pedestrian suspension bridge can be placed in two ways vertical hangers and inclined hangers. The inclined hangers are subjected to more fatigue while vertical hangers are subjected to more fluctuation of forces due to critical load conditions. During critical load conditions, some of the inclined hangers are subjected to excessive stressed while some of them are subjected to a lack of stress. To improve the stability of inclined hangers a horizontal member is to add the system to eliminate the slackness in hangers. These members release some forces from over stressed hanger to slack the hanger. That system is called a modified hanger system. The system shows its validity for 100m span only. The present study analyzed the vertical, the inclined, and the modified hangers under critical loading conditions using nonlinear static analysis for the span of 150m, 200m, and 300m by taking the width and thickness of the deck constant. The result shows improvement in the stability of the hangers.
