Abstract

Abstract

In order to study the thermal-mechanical coupling effect of hot water storage tank under the action of temperature field and earthquake, the geometric model of hot water storage tank was established by using the additional mass method, and the coupling effect between temperature and earthquake was analyzed by using finite element software ABAQUS. The seismic response characteristics of empty tank and hot water full-loaded tank were investigated. The results showed that the angle of the maximum displacement in the X-Y plane and the height of the tank wall of the hot water storage tank were significantly different between the two conditions of empty tank and full-loaded tank; in addition, the position of the maximum displacement would be different when the thermal-mechanical coupling was considered, and the stress of the tank wall when the thermal mechanical coupling was considered was slightly smaller than that when the thermal-mechanical coupling was not considered.Therefore, the influence of two states of empty tank and full-loaded tank as well as the thermal coupling effect should be considered when the seismic design of the hot water storage tank was carried out.
