The invention provides a silo and a silo top structure thereof. The silo top structure comprises a through ring beam, a vestibule truss, a central annular support, solid-web type roof steel beams and a roof horizontal supporting system, wherein the through ring beam is arranged at the top end of the silo; the vestibule truss is supported on the through ring beam; the central annular support is arranged at the middle bottom of the vestibule truss; the solid-web type roof steel beams are symmetrically and radially arranged along a center line of a vestibule, one ends of the solid-web type roof steel beams are hinged to the central annular support, and the other ends of the solid-web type roof steel beams are hinged to and supported on the through ring beam; and the roof horizontal supporting system is distributed between the solid-web roof steel beams. The vestibule truss and the solid-web roof steel beams are combined into a whole through the central annular support, a vertical force resisting system of the roof is formed, the through annular beam at the top of the silo can weaken out-of-plane horizontal loads generated by a roof system, the vertical deformation resistance of the silo top structure is improved, and meanwhile local stress concentration of the silo wall structure can be relieved.
本发明提供一种筒仓及其仓顶结构，仓顶结构包括：贯通环梁，贯通环梁设置在筒仓的顶端；通廊桁架，通廊桁架支撑在贯通环梁上；中心环形支座，中心环形支座设置在通廊桁架跨中底部；实腹式屋面钢梁，实腹式屋面钢梁沿通廊中心线对称放射布置，实腹式屋面钢梁的一端与中心环形支座铰接连接，实腹式屋面钢梁的另一端铰接支撑在贯通环梁上；屋面水平支撑体系，屋面水平支撑体系分布在实腹式屋面钢梁之间。本发明将通廊桁架与实腹式屋面钢梁通过中心环形支座结合为一个整体，形成屋面的抗垂直力体系，筒仓顶部的贯通环梁可以削弱屋面体系产生的面外的水平荷载，在提高仓顶结构抗竖向变形能力的可以同时缓解仓壁结构的局部应力集中。
