Description
Technical Field
The invention relates to the field of civil engineering, in particular to a cable-stayed-cable truss tension structure.
Background
A tension structure is a form of structure that provides rigidity by applying pretension to structural members and can withstand external loads, and is typically composed of cables, rods, membranes, and the like. The structure has light dead weight and large span, and is very suitable for being applied to the field of large-span space buildings such as stadiums, airports, exhibition halls and the like, in particular to awning structures of large stadiums. The most common tension structure type in the stadium awning is an annular cable truss tension structure, which consists of a pressed outer ring beam, a closed inner ring cable and a radial cable truss, and various different structural forms can be obtained by changing the forms of the three structural units. The most commonly used annular cable truss tension structure at present can be divided into two types according to radial cable trusses: a single ring beam double loop rope type and a double loop Liang Shan loop rope type. The single-ring beam double-loop rope type structure needs to be provided with a circle of flying columns between the upper loop rope and the lower loop rope, and in order to improve the vertical rigidity of the structure, the circle of flying columns usually needs to be high, so that the building height is influenced, and the building effect inside a stadium is also influenced. The double-ring Liang Shan ring rope type structure only needs one layer of inner ring rope, but also needs a larger height between the upper ring beam and the lower ring beam of the outer layer in order to improve the vertical rigidity of the structure, and has higher requirement on the overall rigidity of the peripheral ring beam. In addition, even though the vertical rigidity of the structure can be improved by increasing the height difference of the ring cable or the ring beam, the height difference cannot be infinitely increased due to the restriction of the building effect and the like, so the vertical rigidity of such a structure is weak.
In addition, the building form of the tension structure in the prior art is single, and the tension structure has an annular effect of being sealed inside and outside. In recent years, a novel open crescent structure system is also present, but the scale is smaller, and the system is not suitable for the field of large-span space building.
