Abstract

The invention relates to a high-redundancy beam-string truss structure and an implementation method. The high-redundancy beam-string truss structure comprises an upper string truss, a plurality of stay bars, a plurality of stay ropes, a fixed hinged support and a sliding hinged support, wherein the upper string truss is a positively arranged triangular cone space arch truss formed by mutually connecting a plurality of upper string truss rod pieces; two ends of each stay rope are connected with two spherical joints at the lower part of the upper string truss at an interval, and parts of the plurality of stay ropes are alternatively arranged; the plurality of stay bars are vertically connected among the lower part of the upper string truss and the plurality of stay ropes at intervals; the upper end of the fixed hinged support is connected with the spherical joint at the lower part of one side of the upper string truss, and the lower end of the fixed hinged support is arranged on a supporting structure on one side of the upper string truss in a fixing manner; and the upper end of the sliding hinged support is connected with another spherical joint at the lower part of the other side of the upper string truss, and the lower end of the sliding hinged support is arranged on a supporting structure at the other side of the upper string truss in a sliding manner. The high-redundancy beam-string truss structure and the implementation method have the advantages of high structure redundancy, good collapse resistance, simplicity and convenience in construction, excellent safety and the like.

Description

technical field [0001] The invention belongs to the technical field of large-span prestressed steel structures of building structures, and in particular relates to a high-redundancy tension string truss structure and an implementation method. Background technique [0002] The tension truss structure was first proposed by Professor M. Saitoh of Nihon University in 1986. This structure is a new type of hybrid roof system different from the traditional structure. The self-balancing hybrid structure composed of cables and intermediate compression struts is also a relatively successful long-span prestressed spatial structure in the development of hybrid structural systems. [0003] The string truss structure is characterized by a simple system, clear force, and various structural forms, giving full play to the advantages of rigid and flexible materials, and it is simple and convenient to manufacture, transport, and construct, so it has been well applied. In recent years, the lon...
