Research Abstract

In this study, a new bridge system and design method for economical long-span cable-supported bridges is developed. Elasto-plastic large displacement analysis, elastic large displacement analysis which takes displacement-dependent wind load, flutter analysis which takes the cable local vibration into account for long-span cable-supported bridges with an arbitrary configuration are developed. Using 1400-meter cable-stayd bridge models with different size of cross sections, instability analyzes are carried out, then the minimum cross-sectional dimension which ensures safety against above instabilities is presented. With respect to suspension bridges, using a 2500-meter bridge model, the effect of the cable system, such as conventional system, spatial cable system, the Mono cable system and also transversely arranged members, such as cross hanger on flutter onset wind velocity is investigated. It is found the former effect is small and the latter one is prominent. From this study, the conventional system with transversely stiffening system such as cross hanger and rigid hanger is recommended for attaining high aerodynamic stability. Further, damping mechanism of long-span cable-supported bridge is made clear, also, vibration control for increasing flutter onset wind velocity is investigated.
