The　earthquake　table　test　of　the　roof　model　of　National　Gymnasium　is　the　first　time　to　do　the　test　of　so　large　size　of　the　structure　at　home　and　abroad.　The　vertical　and　horizontal　vibration　table　tests　of　the　roof　model　are　conducted.　The　responses　of　acceleration,　displacement　and　stress　of　the　structure　under　the　two-dimensional　earthquake　provide　the　tested　data　for　evaluating　the　seismic　performance　of　the　roof　and　can　be　referened　in　seismic　analysis　of　similar　structure.　At　the　same　time,　the　results　indicate　that　bi-directional　beam　sting　structure　have　good　aseismic　capability　and　is　a　new-style　great　structure,　which　has　favorable　application　in　future.
