Abstract

Abstract: High concrete water-tower is used as research objects, an analytical model of a water-tower foundation is established using the finite element method (FEM). The water-tower foundation is mainly studied under the action of a wind field that considered liquid-solid-soil interaction (LSSI), and the dynamic response of high concrete water-tower is obtained. First, according to the linear filtering method, the simulation of the random wind field is completed using MATLAB. FEM is used to establish LSSI water-tower foundation model and the liquid-solid interaction (LSI) water-tower model. Furthermore, the random wind field is used as an input for the finite element model under two different assumptions. Under the action of the random wind field, the wind-induced vibration response law is studied. Finally, by analyzing the wind-induced responses of the two models, the effects of soil on the wind-induced vibration response of water-tower are studied . The results show that under the assumption of LSI, the wind-induced vibration response of the water-tower differs greatly from the wind-induced response when LSSI is considered. It is found that LSSI is more severe than only LSI for displacement response. Similarly, It is discovered that LSSI is greater than LSI for acceleration and stress responses.
