Description

An industrialized multi-story assembled steel structure frame-prestressed central support system

technical field

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 housing steel structures.

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.

At present, prestressed cables are only used in tension string structures, and have not been used in high-rise structures. The use of prestressed cables as high-rise lateral force-resistant components has not yet been realized in engineering. 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 industrialized multi-story fabricated steel frame-prestressed central support system adds The lateral and longitudinal prestressed central cable supports are used to increase the lateral stiffness of the structure and improve the deformation performance of the structure.
