Abstract
The greatest concern of bridge engineers in the world is maintenance, repair and rehabilitation of bridges. Many bridges, which have been constructed in the age of high growth of economy, sustain the damages by increase of heavy traffics. They need repair and/or strengthening. Characteristics of repair and strengthening works are to be done under loading and vibration. There are few studies in relation to welding to members in service condition though the use of welding in repair and/or strengthening works has many advantages.
This paper describes some experimental and analytical studies on the effect of welding under loading on the deformation behaviors of plates.
