Investigation of the Charlotte Motor Speedway Bridge Collapse

Low cost condition assessment method for existing RC bridges

“…It was a four span, simply supported, precasted and prestressed reinforced concrete bridge spanning a major US highway, see Figure 7. Many interesting details can be found in [31] and [32]. The main cause of the collapse may have been a chloride attack causing the prestressing tendons corrosion on the double T beams.…”

Finite Element Analysis and Design of Test Setup for Determination of Transfer Length in BFRP Prestressed Concrete Beams

“…Pre-stressed concrete (PC) members degrade rapidly when the steel strands are subjected to corrosion thereby decreasing the lifespan of the PC structures. Two major bridge collapses in the past; the failure of the viaduct "S. Stefano" in Italy in the year 1999 [1] and Charlotte's Motor Speedway footbridge in the USA in the year 2000 [2] has been related to the corrosion of the prestressing steel strands. The maintenance of steel (to prevent it from corrosion) and replacement of the assets (which are affected by corrosion) in a short span of time has become a major concern for an economy.…”

Corrosion Protection of Mild Steel and Aluminium in 0.1M and 1m HCL Acid Solutions Using Pterocarpus Osun.

“…Corrosion is the process of degradation or failure of a material resulting from a chemical reaction between the material and its surrounding environment [2].The corrosion challenge has resulted to serious damages to properties, many cases of injuries and death for both humans and animals [3]. A pedestrian bridge in Charlotte, North Carolina, failed due to corrosion of the steel reinforcement, injuring 107 people [4]. Financial losses have been assessed in several studies which concluded that premature degradation costs industrialized nations approximately 3% of their gross domestic product (GDP) [5].Corrosion could be prevented by several methods, one of which involves the use of corrosion inhibitors.…”
