Open full text 1 citations

Abstract

In this paper dynamic behavior of the Ying Zhou main bridge in Luoyang is studied .The finite element analysis software ANSYS is adopted to set up three-dimensional finite element model of a CFT arch bridge of the main bridge .The natural periods and modes of the CFT arch bridge are calculated by using the subspace iteration method. Meanwhile its modal characteristics are analyzed. Some useful conclusions are got by the calculation and analysis of the bridge for the engineering construction.
