Abstract

The invention relates to a high strength steel frame-laminated corrugated steel sheet wall side-resistant cold-formed thin-walled steel structure and belongs to the field of structure engineering. Thehigh strength steel frame-laminated corrugated steel sheet wall side-resistant cold-formed thin-walled steel structure comprises rectangular high strength steel columns, I-shaped high strength steelbeams, connection angle steels, zigzag fish plates, fish plates, corrugated steel sheets, bolts, self-tapping screws, a thermal-insulation, damp-prevention and sound-insulation material, decorative wall boards, cold-formed thin-walled steel composite wall bodies and a profiled steel sheet composite floor, wherein the I-shaped high strength steel beams are arranged at web plates at the two ends andare connected with the corresponding connection angle steels on the corresponding rectangular high strength steel columns through bolts to form a high strength steel frame; and a laminated corrugatedsteel sheet wall is vertically arranged, the upper edge and the lower edge of the laminated corrugated steel sheet wall are connected with the corresponding zigzag fish plates through bolts, the right edge and the left edge of the laminated corrugated steel sheet wall are connected with the corresponding fish plates through bolts, and the high strength steel frame-laminated corrugated steel sheetwall side-resistant structure is formed. The high strength steel frame-laminated corrugated steel sheet wall side-resistant cold-formed thin-walled steel structure improves the deficiency of anti-seismic property of a traditional cold-formed thin-walled composite wall body, has the advantages of strong energy-dissipating capacity, capability of restoration after an earthquake and integration of functions of a structure and a building and can be widely applied to multi-layer building engineering.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to the field of anti-seismic structures. Background technique [0002] Steel structures have the advantages of high material strength, relatively good plasticity and toughness, can be recycled, and are green and environmentally friendly. When used in building structures, they can reduce the structure's self-weight, improve the structure's seismic performance, and speed up construction. It is currently used more and more. The cold-formed thin-walled steel structure gradually developed in the steel structure has the advantages of light structure, high construction efficiency, easy processing and manufacturing, energy saving and environmental protection, and easy dismantling. It is mainly suitable for low-rise buildings with 3 floors and below, and is widely used in North America and Japan. It has been widely used in developed countries and regions such as Australia and Australia,...

Problems solved by technology

However, relevant studies have shown that the "pinching" phenomenon of the load-displacement hysteretic curve of cold-formed thin-walled steel composite walls under reciprocating horizontal loads is more obvious, and its energy dissipation capacity is significantly lower than that of reinforced concrete shear walls and steel plate shear walls. Force wall and steel-concrete composite shear wall make it difficult to realize the "high-efficiency earthquake resistance" of the steel structure system with strong energy dissipation capacity and recoverable after-earthquake when cold-formed thin-walled steel structures are applied in multi-storey buildings in high-intensity areas
