Abstract

In this paper, Taizhou Bridge, a three-tower suspension bridge was investigated to discover the flutter stability of deck under symmetrical construction through FEM(finite element method) analysis and full aeroelastic model tests. The assessment of flutter stability during deck construction stage was performed based on analysis of the monthly maximum wind speed in the past 30 years. In the end, the assessment and management strategy of flutter stability were proposed, which can be referred for other bridges.
