Braced Frame Structure
The raw material used for braced frame structure is steel. Compared with concrete and wood, steel has higher strength, lighter weight and is easy to transport and install.It is suitable for structures with large span, high height and heavy load, such as large factories, venues, super high-rise buildings and other fields. And its strong toughness, good plasticity, the material is more uniform, so the structural reliability is higher. In addition, the braced frame structure steel structure also has the advantages of good sealing, energy saving and environmental protection, which can be used as a large oil pool, pressure pipeline, etc. However, the steel heat-resistance, fire-resistance, corrosion-resistance is also relatively poor, so regular maintenance are required during use. Steel structure is widely used in engineering construction. In addition to the above mentioned uses, it can also be used as steel bridges, steel workshops, steel gates, various large pipeline containers, tower rail structure, etc.
The braced frame structure steel structure has the following characteristics:
High strength, light weight and large rigidity, so it is especially suitable for the construction of large-span and ultra-high and ultra-heavy buildings;
The material has good homogeneity and isotropy, and is an ideal elastomer, which is most in line with the basic assumptions of general engineering mechanics;
The material has good plasticity and toughness, can have large deformation, and can withstand dynamic load well;
The construction period is short: its high degree of industrialization, can carry out a high degree of mechanization of professional production;
High processing accuracy, high efficiency and good airtightness, so it can be used to build gas tanks, oil tanks and transformers;
The steel structure has a light weight;
The reliability of steel structure work is high;
steel vibration (shock) resistance, impact resistance is good;
The industrialization of steel structure manufacturing is relatively high;
The steel structure can be assembled accurately and quickly;
Large indoor space of steel structure;
Easily made into a sealed structure;
Steel structure corrodes easily;
Steel structure has poor fire resistance;
The steel structure can be recycled;
The steel structure construction period is short;
Earthquake resistance: most of the roofs of low-rise villas are sloped roofs, so the roof structure basically adopts a triangular roof truss system made of cold-formed steel components . After the light steel components seal the structural sheet and gypsum panel, a very strong slab structural system is formed. This structural system has a stronger ability of earthquake resistance and resistance to horizontal load. Suitable for seismic intensity of more than 8 degrees;
Wind resistance: steel structure building light weight, high strength, good overall rigidity, strong deformation ability. The weight of the building is only one-0fifth of that of the brick -concrete structure. It can withstand a hurricane of 70 meters per second, so that life and property can be effectively protected;
Durability: The light steel structure house is all composed of cold-formed thin-walled steel component system, and the steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of rust of the steel sheet during the construction , and increases the service life of light steel components. The structural life can reach 100 years;
Thermal insulation: The thermal insulation material is mainly with glass fiber cotton, which has a good thermal insulation effect. The use of insulation panel on the exterior wall effectively avoids the "cold bridge" phenomenon of the wall to achieve a better insulation effect. The thermal resistance value of R15 insulation cotton about 100mm thickness can be equivalent to a brick wall 1m thickness.
