Steel structure building refers to the building structure made of steel materials. Because of its light weight and simple and convenient construction, it is widely used in large factories, stadiums, super high-rise buildings and other construction fields. So what are the advantages and disadvantages of steel structure building?
(1) convenient installation
The strength of steel structure is high, and its elastic modulus is also relatively high, so compared with concrete, wood, steel density and yield strength ratio is relatively low. Moreover, under the same stress conditions, the members of the steel structure have small sections and light weight, so it is more convenient for transportation and installation.
(2) high reliability
The internal structure of steel is more uniform, and nearly isotropic homogenization, so it has a very good ability to withstand impact and dynamic load, as well as very superior seismic performance, so in the practical application, the reliability of steel structure building is very high.
(3) good heat resistance
When the temperature is below 150℃, the change of steel properties is very small, so it is more hot shop use. However, if the surface of the steel structure is exposed to thermal radiation of about 150℃, then the heat shield is needed to protect it.
(4) environmental protection
The steel structure of the house can be 100% recycled, can completely realize recycling, and in the construction and demolition, the environmental pollution is less, so more in line with the requirements of housing industrialization and sustainable development.
(1) high cost
The cost of a steel house is higher than that of a traditional brick and steel house. Because steel structure building is more to new-style material requirement, need to match the material such as heat insulation heat preservation.
(2) low demand
Because the steel structure of the house is the steel skeleton, plus the light material of the wall, roof, so many people still prefer the traditional structure of the house. The standardization that steel structure building compares, standard type, so it is difficult to satisfy consumer to the demand of the home.
(3) radiation intolerance
Steel structure must be aluminized steel, in order to maximize corrosion protection. Steel structures are prone to corrosion in wet and corrosive media.
