Negative gauss curvature cable dome
The invention discloses a negative gauss curvature cable dome. The negative gauss curvature cable dome is composed of inhaul cables in the ring directions, upper oblique inhaul cables in the radial directions, lower oblique inhaul cables in the radial directions and vertical compression bars; the upper oblique inhaul cables in the radial directions are connected with each other in an end-to-end mode to form a negative gauss curvature curve surface; one end of each vertical compression bar is connected with the corresponding lower oblique inhaul cable and the corresponding inhaul cables in the ring directions, the other end of each vertical compression bar is connected with the different corresponding lower oblique inhaul cables and the corresponding upper oblique inhaul cables, and the lower oblique inhaul cables in the outmost ring and the upper oblique inhaul cables are fixed to supporting seats arranged on the periphery of the structure to form the negative gauss curvature cable dome. The curvature forms and member numbers of the negative gauss curvature cable dome are determined according to architectural images, using functions and carrying capacities. The negative gauss curvature cable dome changes the current situation that existing cable domes are each of a positive gauss curvature, and the cable dome can be used in structures of various architectural images. On the premises that the original simple structure, reasonable stress and beautiful images of the cable dome structure are maintained, since the positive curvature and the negative curvature are reverse in the two main directions, the negative gauss curvature cable dome is also a structural style with more excellent vertical bi-directional load bearing performance.
