ROOF, ROOF DESIGN METHOD, AND ROOF DESIGN DEVICE

摘要

[PROBLEMS] To reduce the burden on the lower structure while providing a rise of the roof, and to suppress the labor and cost of the improvement. A roof 11 is a truss-structured roof 11 having a plurality of upper chord members 21 and a plurality of lower chord members 31 that form a curved surface that protrudes upward, and includes a plurality of upper chord members 21 and a plurality of lower chords. Each of the materials 31 is formed in an annular shape with the outer peripheral material 51, the first material 52 extending in the crossing direction Dx and spanning the outer peripheral material 51, and extending in the spanning direction Dy while intersecting the first material 52. It extended in the direction which cross | intersects the 2nd material 53 spanned by the outer periphery material 51, the crossing direction Dx and the spanning direction Dy, and was spanned by the outer periphery material 51, intersecting the 1st material 52 and the 2nd material 53. The reinforcing members 54 of the upper chord member 21 and the lower chord member 31 are formed by a rigid body 60 that is continuous and extends linearly in a plan view. [Selection] Figure 2
