Abstract
This thesis aims to analyze the latest Weight-In-Motion (WIM) data available with the Georgia Department of Transportation. The performance and live load capacity of a bridge at its design stage cannot remain constant as time progresses, leading to the importance of measuring traffic live loads imposed on bridges. The research method involves the use of the National Bridge Inventory (NBI), NCHRP Reports, and Python Programming. The study focuses on the examination of live load demands and thus calculates maximum shear forces and moments for eleven WIM sites. These values are compared with current truck assessment models testing their reliability. Results indicate the need of a new truck configuration classified as the Notional Rating Load (NRL), concluded in NCHRP report 575. Additionally, bridge demand-to-capacity ratios are analyzed for future development through the inquiry of traffic load demand and condition reduction assessment. Finally, this thesis concludes with recommendations for future WIM sites.
