Abstract
Metallic orthotropic deck bridges are incorporated as an efficient structural system in many roadway bridges due to the large reduction in bridge dead load. The current study presents a structural study performed for one of the major roadway bridges, Sayeda Eisha Bridge, located in old Cairo, Egypt. The bridge has been in service for more than 50 years representing one of the limited steel orthotropic deck systems in the province. The study was performed upon the request of Cairo governorate in order to determine the current condition of the bridge and evaluate its ability to sustain given loads. Moreover, it was required to evaluate the condition of the bridge considering the accidents it was subjected to throughout its service life. The assessment study included visual inspection, and numerical analyses in addition to proposing suitable repair methodologies. In the current research, overview of the performed study is listed. In conclusion, the study summarizes the steps performed during the study; lists study observations; exhibits numerical analysis results and explores proposed repair methodologies. The study is part of the efforts made to enhance the transportation sector in Egypt.
