Flutter Analysis Software Prototype For Long Span-Bridge

Abstract

In long span bridge projects, wind can give significant influence on the bridge structure. Previous experience and research shows that wind effect could lead to the problem of safety and serviceability. It can even cause instability of the whole bridge structure due to its extremely flexible structural characteristics. Flutter is one of the most important phenomena to be considered during the design of long span bridge. There are many methods available for flutter prediction of long span bridge including numerical analytical method. Flutter software usually developed in the laboratory environment with significat limitation in the input and output process of the analysis. This reseach is intended to develop a software for flutter analysis for both suspension bridge and cable stayed bridge which is easy to use. The software is design to be installed in PC under wondows platform. Input and ourput modul is included in the software to have a user friendly software. Foe case study, Akashi Kaikyo bridge is analyzed and presented in this papper
