SEISMIC RESPONSE BEHAVIOR USING STATIC PUSHOVER ANALYSIS AND DYNAMIC ANALYSIS OF HALF-THROUGH STEEL ARCH BRIDGE UNDER STRONG EARTHQUAKES

This paper presents the seismic response behavior o f the static pushover and dynamic response analyses of a half-through steel arch bridge subjected to earthquake waves. The static pushover analysis were carried out using three loading cases which are considering the dead load, live load, impact load and earthquake load, according to Japan Specifications for Highway Bridges (JSHB) loading condition. These results were being compared with the results from dynamic analysis. The dynamic response analyses were carried out using earthquake waves in transverse and longitudinal directions in order to investigate the seismic behavior of the arch bridge model.
