TÓM TẮT
This paper presents the importance of dynamic interaction (coupling) between a three-axle vehicle and the cable-stayed bridge. A finite element method (FEM) for computing the dynamic response of cable-stayed bridge subjected to dynamic wheel loads is carried out, and used to investigate on a three-span steel cable-stayed bridge traversed by a five degree of freedom three-axle vehicle model. The vibration of the cable-stayed bridge was analyzed with various vehicle speeds. The braking effects of the vehicle are varied to assess the amount of interaction between the vehicle and the cable-stayed bridge. Dynamic analysis results show that in most cases the calculated values of impact factors (IM) could be higher than that recommended by the relevant codes and therefore the offered rations for impact factor are underestimated. In designing a highway bridge, we recommend that such criteria should be considered the vehicle speed and its braking effectsabortion stories gone wrong information about abortions teenage abortion factscvs weekly sale cvs print prescription savings cards
