Multi-storey and high-rise assembly type modularized self-resetting steel-structure special-shaped column frame system

Abstract

The invention discloses a multi-storey and high-rise assembly type modularized self-resetting steel-structure special-shaped column frame system, and belongs to the technical field of structural engineering. The frame system comprises outer joint modules, corner joint modules and inner joint modules. The invention provides a novel assembly type module. Joints and inflection points of an intercepted frame part are assembled as a whole, the inflection points of the frame part are small in bending moment, a weak connection mode can be adopted between columns, a connection mode is flexible, and steel consumption and connection difficulty are reduced. Due to the design of prestress steel strands, the post-earthquake residual deformation of frame joints can be reduced, and the self-resetting effect is achieved. Due to the arrangement of supporting plates, cover plates and outer ribs, beams can be precisely positioned, and meanwhile the stability of the joints is improved. The outer ribs are arranged in beam flanges, so local bearing capacity is improved, and meanwhile the attractiveness effect can be achieved. In production and construction of the steel-structure system, modularization, factorization, standardization and assemblage are combined, industrialized production is achieved, and construction cost is reduced.

Description

technical field [0001] The invention relates to a multi-high-rise assembled modular self-resetting steel structure special-shaped column frame system, which belongs to the technical field of structural engineering. Background technique [0002] 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, my country's steel output exceeded 700 million tons in 2011, 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. [0003] At present, the systematic research on high-rise steel structure residences at home and abroad is in its infan...

Problems solved by technology

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.
