Seismic Responses Analysis of Suspended Ceiling Structure Attached to Large LNG Storage Tank
The suspended ceiling (SC) of LNG storage tank on land is mainly composed of hanger rods, reinforcing rings, and aluminum panels. The hanger rods are prone to damage during earthquakes, which will affect the safe operation of the whole storage tank. In order to facilitate the study of the response of the SC under horizontal seismic shaking, the finite element models of the hanger rods with four different sections, including rectangular, circular, thin-walled circular tube, and groove shape, were established using the ABAQUS software. By inputting EL-Centro horizontal seismic waves, the dynamic time-history analysis is carried out for four hanger rod models with different sections. The response characteristics of acceleration, displacement and internal force with time are obtained, and the comparative analysis results of the maximum peak acceleration (MPA), maximum peak displacement (MPD), and maximum peak internal force (MPIF) at each measuring point are obtained. The results show that the shape of the section has obvious influence on the seismic response of the hanger rods, and the amplitudes of the acceleration-time and displacement-time curves of the hanger rods with different sections are different, and the MPA, MPD and MPIF of the hanger rods are closely related to the shape of the section.
