Column and curved beam horizontal and flexible connection space structure system

Abstract

The invention provides a column and curved beam horizontal and flexible connection space structure system. Columns and curved beams are horizontally and flexibly connected through horizontal and flexible connecting devices, each horizontal and flexible connecting device comprises a column connector, a curved beam connector a and a steel pull rod for connecting the column connector with the curved beam connector. A vertical suspending connecting device is further connected onto each curved beam and comprises a curved beam connector b and a movable steel suspending rod. The column and curved beam horizontal and flexible connection space structure system is a grid structure and suspended-cable structure combined space structure system. In a space truss structure system, the strength and ductility of a grid curved beam structure are improved, bending resistance bearing capacity of the curved beams is remarkably improved, and deflection deformation of the curved beams is reduced. In a suspended-cable structure, suspended steel structure curved beams are connected through flexible suspending rods. The column and curved beam horizontal and flexible connection space structure system has the flexible connection characteristic, accordingly is simple in overall appearance, even in stress, good in anti-seismic energy dissipation performance and easy to repair and maintain and meets the comfort degree requirement of a suspended steel structure.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a horizontal flexible connection space structure system of columns and curved beams. Background technique [0002] In recent years, domestic and foreign space structures have developed vigorously, with novel types of buildings and various forms and types. According to the form and classification of space structure systems, they can be divided into thin shell structures, grid structures, reticulated shell structures, suspension cable structures, and membrane structures. equal space structure. However, it is rare to combine two or more space structures in the space structure system and apply them to the atrium structure system with large bays. [0003] At present, in the atrium structure of the large bay, the grid structure and the suspension cable structure are widely used. However, the rigid joints of the grid structure are mostly welded. Under the action of earth...

Problems solved by technology

However, the disadvantages of complex construction and long construction period of reinforced concrete structures have affected its development in space structures, and if the curved beam is a suspended structure, it will increase the difficulty of aerial formwork at the construction site, and the self-heavyness and poor seismic performance; pure Most steel structures adopt the form of truss beams, box beams or H-shaped steel beams. These forms are rigidly connected and require large embedded parts for supports, and most of them are brittle failures under the action of earthquakes.

Pure steel structure is greatly affected by temperature changes, takes up a lot of space, is expensive, and does not have a good architectural aesthetic effect
