Mean wind load induced incompatibility in nonlinear aeroelastic simulations of bridge spans

Zhitian ZHANG

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 3, Pages 605-617 doi: 10.1007/s11709-018-0499-x

Abstract: A kind of incompatibility is found during the simultaneous simulation of the mean wind and aeroelasticIt is shown that, in cases of low wind speeds, the IF-denoted model reflects correctly the mean windload properties, and results in correct mean structural responses; in contrast, the RF-denoted modelAt very high wind speeds, however, even the IF-denoted model can lead to significant deviation from themodel is put forward in this work.
