Specially, the response of long cantilevered truss under vertical earthquake was examined. The shaking table expriment confirmed the rightness of calculation simulation, and showed the overall structural has a good anti-seismic capacity to achieve the scheduled fortification goal.
Keywords: Xinjiang International Exhibition Center; long span steel structure; long cantilevered stell truss; vertical vibration; seismic resistance performance
