Are Steel Structure Schools Practical?
Building a school is a very cautious construction project, because the school has a relatively large and fixed flow of people, and they are the flowers of the motherland. It is also the hope of countless families and the future of a country. Security issues are bigger than the sky. Therefore, school building requirements are very strict. Now many places have begun to use steel structures to build schools, so are steel structures suitable for school buildings?
Since many places have begun to use steel structures to build schools, it means that steel structures are definitely suitable for school buildings. Here we analyze the practicality of steel structure schools from several aspects.
1. Security. For all types of steel structure buildings, the safety performance has been verified. As long as the design is reasonable, the construction is correct, and without shoddy work or useing inferior material, there will be no problem with safety. School buildings are government projects, and construction safety is the top priority. The government will usually go through multiple rounds of bidding and selection to select the most qualified and responsible construction unit to undertake the construction. Therefore, there is no need to worry about the safety of steel structure schools.
2. Earthquake resistance. In fact, the most important thing when choosing steel structure construction for schools now is the seismic performance of steel structure buildings. Especially in areas with frequent earthquakes and earthquake risks, steel structure schools are the best choice. Compared with reinforced concrete and civil structures, steel structures have relatively stronger seismic resistance. Houses with concrete structures are better able to withstand compression but not tension. When an earthquake strikes, the house is prone to overall collapse under the cyclic load of seismic waves.
The steel structure has good ductility and can offset the energy consumption of seismic waves. According to calculations, the strength of steel is about 8 times that of concrete and its density is only 3.2 times that of concrete. Therefore, for the same bearing capacity requirements, the weight of steel structures can be much lighter than the weight of concrete components. In addition, the cross-section utilization rate of steel components is high. Generally, when building high-rise buildings, the use of steel structures can reduce the structural weight by about 40%-50%. Buildings that have successfully slimmed down have high strength and are naturally not afraid of earthquakes. The steel structure can absorb and consume the energy input by the earthquake through deformation, so it has a high resistance to strong earthquakes and can effectively reduce the seismic response.
The destructiveness of earthquakes, especially strong earthquakes exceeding magnitude 6, will cause irreversible damage to people’s lives and property safety. As a gathering place for special groups and dense crowds, schools need good earthquake resistance.
3. High construction efficiency. The steel structure is simple to install and has high construction efficiency. Most components can be processed in the factory and then assembled on site, which can greatly shorten the construction period compared with traditional concrete structures. Especially for post-earthquake reconstruction projects, rapid installation and put into use is very important. It can solve the urgent needs of people in disaster areas. It is even more important for schools, which can provide a good learning environment as quickly as possible.
4. Steel structures with large spans and large spaces have greater spatial flexibility and can create larger classrooms, libraries, indoor sports venues, etc. For schools, these functions can provide greater convenience for children.
5. Steel structures are recyclable and have better sustainability. Steel structure buildings have a high recyclability rate and can reduce resource waste. Steel structure buildings have a long service life if they are well maintained, and steel structure schools can adopt energy-saving designs, such as using solar power to generate electricity, adding natural ventilation systems, reducing energy consumption and reducing the impact on the environment.
To sum up, the practical performance of steel structure schools is very good and they are fully qualified for school construction. However, steel structure buildings are more expensive than ordinary concrete buildings, and they require later maintenance and upkeep, which is more complicated. Therefore, when choosing a steel structure school, you must comprehensively consider various factors and make evaluations and decisions based on specific circumstances.
