This study is aimed to develop seismic performance improvement measures for steel arch bridges. Ultimate strain formulas applicable for axial force ratio varying from 0.0 to 1.0 were first proposed for various sectional segments. A dynamic verification with the use of proposed formulas was then applied to a steel arch bridge. The analysis showed that the bridge demonstrated sufficient seismic performance under longitudinal earthquake excitation, but insufficient when subjected to transverse earthquake excitation. To improve seismic performance in the lateral direction, use of high ductility sections is proposed. The result indicated that such a measure is very effective in improving transverse seismic performance.
