Designing, Updating and Calibrating of a Full Bridge Aeroelastic Model for an Arch Bridge

TU Xi, MA Ru-jin, CHEN Airong

Abstract: The experience for designing, updating and calibrating of a full bridge aero-elastic model for an arch bridge is summarized. A half-through arch bridge with the span of 450m is used as a study case. The designing of full bridge model is the basis of the wind tunnel testing, but due to its structural complexity, the designing of full bridge model for an arch bridge becomes more complicated. The dynamic characteristics of the arch bridge are firstly analyzed. A FEM model for the full bridge aero-elastic model is built and the influences of some structural parameters on the dynamic properties are investigated. During the model updating, Mass Influence Matrix Method (MIMM) is proposed which can remarkably reduce updating times and proves to be a practical and effective method. As a supplement for calibrating the full bridge aero-elastic model, Static Rigidity Test (SRT) of model is used before wind tunnel test. In the end, the process of SRT is presented for the arch bridge.

Key words: long-span arch bridge, full bridge aero-elastic model, dynamic characteristics, Mass Influence Matrix Method, Static Rigidity Test
