Abstract
Many steel bridge piers have been used to highway bridges in urban area. Beam-to-column connections of steel bridge piers have been fabricated by thicker plates compared to general sections due to considering shear-lag phenomenon in the design calculation of beam-to-column connections. After the Kobe Earthquake, plate thickness of beam-to-column connections increases with increase design earthquakes. Consequently, there are many difficulties in fabrication, design, and transportation of the connections. The purpose of this study is to grasp effects of beam-flange geometry on elasto-plastic behavior of beam-to-column connections of steel bridge piers with circular columns by using experimental and analytical investigations.
