材２の中間に固定する。<A> Vertical support member. The dome structure is a curved roof frame 1 with a high center.
It is constituted by. Both lower ends of the curved roof frame 1 are fixed to a vertical support member 2. When the roof frame 1 is composed of a truss, the end of the upper chord 11 of the truss is fixed to the upper end of the support member 2, and the end of the lower chord 12 of the truss is fixed to the middle of the support member 2.

When the roof frame 1 has a truss structure, the horizontal members 3 extend outward from the same position as the lower chord mounting position of the truss.
Overhang. The front end of the horizontal member 3 and the upper and lower ends of the support member 2 are connected by diagonal members 4, respectively. As a result, it is possible to form a truss that has the vertical support member 2 as one side and that protrudes outside the support member 2.

In this way, the lower columns 5 arranged on the curve are connected and restrained by the column connecting beams 6 in the circumferential direction. In addition, horizontal material 3
Truss connecting beams 8 that connect adjacent trusses are arranged at each of the triangular apexes formed by the diagonal members 4 and the vertical support members 2. By connecting the trusses with the truss connecting beams 8, the trusses can be integrally restrained.

ンダーな独立柱で構成することができる。According to the dome roof support structure of the present invention, as described above, since the legs of the vertical support member 2 connecting the lower end of the roof frame 1 are supported by the pins 51, snow, wind, earthquake, etc. In the case of the disturbance described above, the connecting member 8 in the circumferential direction works effectively by the deformation effect of the roof due to the rotation of the truss with the support member 2 as an element, so that the thrust transmission to the lower support 5 can be reduced. In this case, the horizontal rigidity of the truss and the lower support 5 is optimally set in consideration of the balance between the thrust force and the deformation of the leg of the vertical support member 2. The lower group of struts 5 can be formed of slender independent columns because the brace 7 can be arranged between the struts 5 in the circumferential direction to control the normal-direction seismic reaction force.
