Abstract In this paper, the v ehicle-curv ed bridg e systen i s studied. The spaced analy tica l model of a t rain passing on a curved bridg e wi th a span o f 32m, as ex ample, i s simulated by computer. The dynamic response o f the bridge derai lment quo tient , the reduction rate of the w heel load a nd the t rain stabi li ty a re calcula ted. The results are compared wi th the st raig ht bridg e. All o f the resul ts show tha t the proposed method i s ef fective in use.
