Abstract
This paper aims to clarify the effects of transverse stiffeners on local vibrations in component plates of thinwalled steel members caused by a high-speed traveling load. The dynamic responses of the component plates with a transverse stiffener are calculated by means of finite strip method. The component plates and the transverse stiffeners are divided into a number of finite strips which are at right angles to the longitudinal direction of the component plate. The results from the analyses are as follows: 1) the local vibrations of the component plates are reflected in the transverse stiffener; 2) the maximum amplitude of the local vibrations of the component plates with the transverse stiffener increases when the speed of the traveling load approaches the minimum value of the phase velocity curve
