The invention provides a full-tensioning cable truss building structure system and a form adjusting method thereof. The full-tensioning cable truss building structure system comprises a rigid outer ring beam, an upper ring cable, a lower ring cable, a plurality of upper radial cables, a plurality of lower radial cables, a plurality of supporting rods and a plurality of stay cables, wherein the upper ring cable and the lower ring cable are arranged on the inner side of the rigid outer ring beam, the upper radial cables are arranged between the upper ring cable and the rigid outer ring beam, thelower radial cables are arranged between the lower ring cable and the rigid outer ring beam, and the supporting rods are arranged between the upper ring cable and the lower ring cable; the stay cables are arranged between every two adjacent supporting rods respectively, and the rigid outer ring beam is in a saddle shape. The rigid outer ring beam only needs to be vertically constrained, and the whole structure forms a self-balancing system. The initial length (initial stress) of the stay cables arranged between every two adjacent supporting rods is adjusted so that the shape of the whole-tensioning cable truss building structure system can be adjusted.
Description
technical field [0001] The invention relates to the field of building structure design, in particular to a fully tensioned cable truss building structure system and a form adjustment method thereof. Background technique [0002] Flexible fully tensioned structures are mainly composed of tension members (such as cables, membranes, tie rods, etc.) or tension members and less compression members, which maintain structural shape and stiffness under tension. [0003] In the traditional structure, the structure obtains the stiffness from the geometry and the material, and the structure which mainly obtains the stiffness from the geometry and the material is the so-called rigid structure. The flexible tension structure is a statically indeterminate and dynamically indeterminate system, and its own stiffness cannot maintain a stable initial state. The stability of its initial state must be guaranteed by the geometric stiffness provided by the prestress. The design of fully-tensione...
