Problems solved by technology

[0002] With the construction of a large number of long-span spatial structures, buildings are developing towards a comprehensive direction with complex shapes and diverse functions. Architects are no longer satisfied with regular shapes, large spans, or even just making a fuss on the plane. , considering the aesthetic effect on the facade, the inclined column components are boldly used. However, the overall structure of the inclined column produces an outward overturning moment, which weakens the overall rigidity of the overall structure. At the same time, the inclined column causes a large column base on the foundation Bending Moment and Horizontal Thrust

Embodiment Construction

[0018] A stadium project is taken as an example to illustrate the force-bearing structure of the inclined column and the large-span roof of the present invention.

[0019] Firstly, the lower section 7 of the peripheral slanted column, the upper section 6 of the slanted column and the straight column 9 are successively established. The overall plane is elliptical, and the angle between the surrounding slanted column and the ground is about 50°, which is divergent, as shown in Figure 1, Figure 2, Figure 3. And the internal frame structure 16, as shown in Figure 4, the internal frame structure 16 and the straight columns can be removed after reaching the strength, and the outer ring inclined columns 8 can only be removed after the large-span steel roof 5 is completely installed. Among them, when the slanted column is only calculated separately with the substructure, the roof is applied to the top of the slanted column as a load, and the maximum displacement of the column top is...

Abstract

The invention relates to an inclined column and long-span roof coupling stress structure. The thickness of a long-span roof is reduced, the overturning moment generated by an inclined column to the whole structure is reduced, an overall stiffness contribution of the inclined column to the whole structure is increased, and meanwhile the large column bottom bending moment and horizontal force which are caused by the inclined column to a foundation are reduced; the structure ductility is increased, and the reliability of the structure is improved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering steel structures, and in particular relates to a structure in which a slanted column and a large-span roof are coupled and subjected to force. Background technique [0002] With the construction of a large number of long-span spatial structures, buildings are developing towards a comprehensive direction with complex shapes and diverse functions. Architects are no longer satisfied with regular shapes, large spans, or even just making a fuss on the plane. , considering the aesthetic effect on the facade, the inclined column components are boldly used. However, the overall structure of the inclined column produces an outward overturning moment, which weakens the overall rigidity of the overall structure. At the same time, the inclined column causes a large column base on the foundation Bending moment and horizontal thrust. How to reduce the overturning moment of the slanted column to ...
