Spatial structure system of horizontal flexible connection between columns and curved beams

Abstract

The invention provides a spatial structural system for horizontally flexible connection of columns and curved beams. The columns and curved beams are connected by a horizontal flexible connection device. The horizontal flexible connection device includes a column connector, a curved beam connector a, a column connector and The steel tie rod of the curved beam connector; the curved beam is also connected with a vertical suspension connection device, and the vertical suspension connection device includes a curved beam connector b and a movable steel suspender. The invention adopts a space structure system combining a grid structure and a suspension cable structure. In the grid structure system, the strength and ductility of the grid curved beam structure are improved, the bending bearing capacity of the curved beam is significantly increased and the deflection deformation of the curved beam is reduced. In the suspension structure, flexible suspenders are used to connect the suspended steel structure curved beams. The flexible connection features make the overall appearance simple, uniform in force, good in seismic energy consumption, easy to repair and maintain, and meet the comfort of suspended steel structures. Require.

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
