摘要：

Experimental and theoretical studies have been performed to determine the dynamic behavior of bridges crossed by the Korean high-speed train (KHST). Through this study, significantly amplified dynamic responses compared to static responses of the bridge crossed by trains running at speed close to the critical speed have been obtained. The numerical method technique presented in this study shows reasonable results concerning the dynamic behavior analysis of bridges under trains running at high-speed. In the case of the KHST, train-bridge interaction effects related to the dynamic response of the bridge appeared to be significant at every speed. (C) 2003 Elsevier Ltd. All rights reserved.
