Influence of Upper Bent Structures on Dynamic Response of Intake Tower

WU Zuoguo

Abstract

Based on the intake tower of a large-scale hydraulic engineering in China,the structure analysis software ADINA is adopted to establish three-dimensional nonlinear finite element model of tower-water body-foundation fluid solid coupling by simulating water body with potential flow element.Then it analyzes the natural dynamic characteristics and dynamic responses of the intake tower and its upper bent structures.Finally,the influence of the upper bent structures of intake tower on its dynamic responses is studied.The results can provide reference for seismic design of intake towers.
