Performance Analysis of a New Space Mesh Shell Structure

For the problem of exceeding the tensile force limit of large-span mesh shell structural members with bolted ball nodes， a new spatial mesh shell structural form was proposed， and the new mesh shell structure was analyzed in comparison with the quadrangular cone mesh shell structure to explore the superiority of the structure. The parameters of the structure， such as side-to-side ratio， mesh shell thickness， mesh size， and so on， were analyzed in several cases. The change rule of structural strength， steel consumption， and other indexes with the above parameters was obtained. The study shows that the new space mesh shell structure form can significantly reduce the tension of the lower chord member， meet the strength requirements of the bolted ball node， and broaden the span range of the bolted ball node.
