Abstract
The seismic performance of pillar-free subway stations is an important guarantee for the safe operation of subway.In this paper,based on the background of a two-storey pillar-free subway station in Jinan,the seismic analysis of large-span pillar-free flat roof subway station is carried out by time-history analysis method under the action of E2 and E3 earthquakes based on the finite element software Midas GTS-NX.The results show that:under the two kinds of earthquakes,the maximum relative displacement of the structural plate is located at the roof support,but the maximum relative displacement of the same layer of the plate tends to be close;The interstory displacement and interstory displacement angle of the lower structure are greater than that of the upper structure;The bending moment and axial force value of the structural plate of the pillar-freestation gradually increase from the mid-span to the support,and the maximum bending moment andaxial force value are distributed in the position of the structural plate support.关键词
