Abstract

Abstract

The composite structure which is composed of cable-supported arch truss and single-layer cylindrical reticulated shell structure combines the advantages of cable-supported arch truss structure and single-layer reticulated shell structure, both the horizontal thrust to the supporting and the longitudinal span of the single-layer reticulated shell can be reduced, and the stability of the structure can be improved, resulting in longer span of the structure. Based on a long-span coal shed steel structure roof with a 198 m span, which needs to be supported on 15 m high single-row concrete columns, the design and analysis of the long-span cable-supported arch truss and single-layer cylindrical reticulated shell structure was carried out.After optimizing the prestress of the structure, the static and dynamic characteristics of the structure were analyzed in detail, the feasibility of the structure spanning nearly 200 m span was demonstrated then, and the internal force and deformation distribution of the structure under various possible load conditions were revealed. The ANSYS finite element analysis software was used to calculate both the linear elastic buckling characteristic value of the structure and the ultimate bearing capacity considering the double nonlinearity of material and geometry.
