Description

An industrially assembled special-shaped column steel structure frame-eccentric support system

technical field

The invention relates to an industrially assembled special-shaped column steel structure frame-eccentric support system, which belongs to the technical field of structural engineering.

Background technique

my country's annual urban and rural housing area is 2 billion square meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Iron and Steel Association, in 2011, my country's steel output exceeded 700 million tons, ranking first in the world's steel output for 16 consecutive years. Our country is less than 4%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of steel structures for houses (including residences).

At present, the systematic research on high-rise steel structure residences at home and abroad is in its infancy, and the innovation of industrially assembled high-rise steel structure systems is imperative. A lot of welding is used in the construction of traditional steel structure residential buildings, the construction speed is slow, and the pollution to the environment is serious. The most important thing is that the quality of the welds is not suitable for control, which seriously affects the safety performance of the building.

In the traditional steel frame structure system, the lateral rigidity of the structure is difficult to meet the requirements, and the deformation is large, which is easy to cause damage to non-structural components. The industrially assembled special-shaped column steel structure frame-eccentric support system adds lateral And longitudinal eccentric support, which improves the lateral stiffness of the structure and improves the deformation performance of the structure.

In the traditional structural design and analysis, the beam-column joints in the frame structure are generally treated as ideal rigid joints or hinged joints. Rigid joints are generally considered to be the most ideal form of seismic joints because of their large bearing capacity and stiffness, and are widely used in the joint connection design of frame structures in seismic areas. However, earthquake experience shows that the rigid beam-column joints of buildings have different degrees of brittle failure. The steel frame structure with welded rigid joints is prone to brittle failure due to the poor ductility of the joints, and the construction is also difficult; although the hinged joints are simple in structure, their stiffness and energy dissipation performance are poor, which is not good for the seismic resistance of the structure; Rigid joints have the advantages of both, with higher strength and stiffness, better ductility and energy dissipation performance, thus reducing earthquake damage to a large extent.

Contents of the invention

Its purpose is to combine modularization, factoryization, standardization and assembly in the production and construction of the steel structure system, realize factory production, on-site quick assembly, and improve the construction speed on the premise of ensuring the construction quality. The construction period is reduced and the project cost is reduced. The structural system can realize the rapid installation of the main steel structure frame and lateral force-resistant members, and can resist earthquake and wind loads, reflecting the advantages of steel structures. In addition, semi-rigid joints are used for beam-column joint connection in the present invention, and the semi-rigidly connected steel frame has a small initial lateral stiffness, but a large ductility coefficient and good energy dissipation capacity, which can well meet the seismic requirements under the action of rare earthquakes.
