Abstract

The invention discloses a double-layer vierendeel truss structure system of a large cantilever structure, comprising a floor frame. The floor frame comprises frame columns (1), frame beams (2) and cantilever beams (3). The double-layer vierendeel truss structure system of the large cantilever structure is characterized in that a plurality of main truss columns (4) are arranged between the upper and lower frame beams (2) of the floor, the upper and lower frame beams (2) of the floor are connected with the main truss columns (4) to form a first-layer vierendeel truss structure, a plurality of auxiliary truss columns (5) are arranged between the upper and lower cantilever beams (3) of the floor, the upper and lower cantilever beams (3) of the floor are connected with the auxiliary truss columns (5) to form a second-layer vierendeel truss structure, and the first-layer vierendeel truss structure and the second-layer vierendeel truss structure are connected to form the double-layer vierendeel truss structure system of the large cantilever structure. The double-layer vierendeel truss structure system of the large cantilever structure has a simple structure and is convenient to construct. A space frame structure system is formed by two layers of vierendeel trusses. The double-layer vierendeel truss structure system of the large cantilever structure can meet the structure stress and deformation requirement under the condition of adopting the small beams.

Description

technical field [0001] The invention relates to a truss structure system, in particular to a double-layer vierendeel truss structure system with a large overhang structure. It belongs to the field of building structure. Background technique [0002] In modern buildings, with the continuous development of construction technology, a large number of large cantilevered building structures have appeared in modern buildings. While the length of the cantilever increases, the bending moment borne by the cantilever beam is in accordance with the square relationship of the cantilever length And the rapid increase, the resulting deflection deformation increases rapidly with the cubic relationship of the length of the cantilever, and the vibration control of the cantilever section has become the main problem at present. cannot be increased accordingly. Therefore, the stress, deformation and vibration control of the large overhanging building structure are the problems to be solved by ...
