What are the advantages of steel structure houses?
Steel structure building is a structural method used in many architectural designs now. In traditional building construction, because it can no longer meet people’s needs, steel structure houses construction began to appear in front of us.
Compared with reinforced concrete structures, high-rise steel structure buildings are generally softer, and the lateral displacement values under the action of wind loads and earthquakes are larger. If the building swings or twists greatly under the action of gust of wind, it will have a great impact on the feeling of the human body, often making people feel uncomfortable and sometimes even unbearable. Studies have shown that the human body is most sensitive to the acceleration of wind vibration. In order to ensure a good working and living environment for high-rise steel structure engineering buildings under the action of wind, it is necessary to adjust the maximum acceleration parallel to the direction of wind load and perpendicular to the direction of wind load. limit.
Design of steel structure house
When the lateral deformation of the building under the action of wind load or frequent earthquakes is too large, it will cause damage to the building decoration materials and damage to the non-structural components, resulting in residual deformation in the steel structure engineering components. In the event of a rare earthquake, the deformation of the steel structure house will cause a great effect, the serious damage of the non-structural components will also cause personal injury, and the excessively inclined building will also cause the psychological panic of the residents. At this time, in addition to ensuring that the structure does not collapse, the maximum deformation should also be limited.
It can be seen that the high-rise steel structure building must have sufficient lateral stiffness under the action of wind load and earthquake, which requires the lateral displacement value to be limited in the structural design. The lateral displacement limit is divided into the overall relative displacement and the There are two kinds of relative displacement between houses, among which the limit of relative displacement between floors is more important.
Advantages of steel structure houses
1. Compared with traditional buildings, steel structure houses can better meet the requirements of flexible separation of large bays in buildings. By reducing the cross-sectional area of columns and using lightweight wall panels, the area utilization rate can be increased, and the indoor effective use area can be increased by about 6 %.
2. The energy saving effect is good. The walls of the steel structure house are made of light energy-saving standardized C-shaped steel, square steel and sandwich panels, which have good thermal insulation performance, good seismic resistance, and save energy by 50%.
3. The use of steel structure system in residential buildings can give full play to the good ductility, strong plastic deformation ability of steel structure, excellent seismic and wind resistance performance, which greatly improves the safety and reliability of residential buildings. Especially in the event of earthquakes and typhoons, the steel structure can avoid the collapse of buildings.
4. The total weight of the building is light, and the steel structure residential system is light in weight, which is about half of the concrete structure, which can greatly reduce the basic cost.
5. The construction speed is fast, and the construction period is at least one third shorter than that of the traditional residential system. It only takes 20 days and five workers to complete a 1,000-square-meter building.
6. The environmental protection effect is good. The amount of sand, stone and ash used in the construction of steel structure houses is greatly reduced. The materials used are mainly green, 100% recycled or degraded materials. When the building is demolished, most of the materials can be reused or degraded without causing waste. .
7. With flexible, solid, and large room design, the indoor space can be divided into multiple schemes, which can meet the different needs of users.
8. In line with the requirements of construction industrialization and sustainable development. The steel structure is suitable for mass production in factories and has a high degree of industrialization. And it can integrate advanced products such as energy saving, waterproofing, heat insulation, doors and windows into one, complete application, integrate design, production and construction, and improve the level of the construction industry.
