Damage condition and field loading test of the continuous non-composite I-girder steel bridge with deck joints used for about 50 years

Abstract

In order to investigate the structural behavior of an old continuous non-composite steel I-girder bridge with deck joints, which had been in service for five decades in cold region of Hokkaido, Japan, visual inspection and static/dynamic loading tests were conducted. In addition, analytical study using frame analysis and FE analysis were carried out. It is found that composite action between concrete deck and steel girders is clearly shown through comparison between analytical values and measurement values, and that there is a little difference between FEA and measurement values.
