Structural Behavior and Condition of Douglas Line Elevated Structure
Mohsen A. Issa
January 1996
GCP-96-1
This paper details the results of a field investigation carried out at several locations along the Douglas line of Chicago's elevated train to determine the adequacy of loading conditions. The report poses the question: does the system require replacement or partial repair and rehabilitation where necessary? The content of this report is highly technical in nature due to the emphasis on structural analysis.
