The invention provides a silo and a silo top structure thereof. The silo top structure comprises a through ring beam, a vestibule truss and solid-web roof steel beams, wherein the through ring beam is arranged at the top end of the silo; the vestibule truss is supported on the through ring beam through a shear-resistant embedded part; and the solid-web roof steel beams are symmetrically arranged in a fishbone mode along a center line of a vestibule, one ends of the solid-web roof steel beams are directly hinged to the lower chord of the vestibule truss, and the other ends of the solid-web roof steel beams are hinged to the through ring beams through reinforced concrete or steel buttresses. The vestibule trusses and the solid-web roof steel beams are combined into a whole, a vertical force resisting system of the roof is formed, the through ring beams at the top of the silo can weaken out-of-plane horizontal loads generated by a roof system, and local stress concentration of the silo wall structure can be relieved while the vertical deformation resisting capacity of the silo top structure is improved.
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，通廊桁架通过抗剪埋件支撑在贯通环梁上；实腹式屋面钢梁，实腹式屋面钢梁沿通廊中心线对称鱼骨式布置，实腹式屋面钢梁的一端与通廊桁架下弦直接铰接连接，实腹式屋面钢梁的另一端通过钢筋混凝土或钢支墩与贯通环梁铰接连接。本发明将通廊桁架与实腹式屋面钢梁结合为一个整体，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。
