The steel structure has high seismic performance, no pollution, green, environmental protection, sustainable development, and can be reused after 100 years of use, which has been recognized by the world. From the perspective of office building structure, all steel structure can bring good seismic effect, and is also one of the most important means of office building seismic resistance. This kind of building structure has already been widely used internationally.



Today, when office building products emerge in endlessly, steel structure has become an important standard to measure whether an office building has the top quality, and will also become the development trend of office building products in the future. What advantages does steel structure have to make today's office buildings and even urban buildings look good? In terms of the dead weight of the building, compared with the steel-concrete structure, the full steel structure has light deadweight, and the dead weight of the characteristic steel structure is generally about two-thirds or one-half of that of the steel-concrete structure; The steel structure building with light deadweight will greatly reduce the seismic force to play a role in mitigating, thus protecting the stability of the entire building. From the perspective of building toughness, the all steel office building has good toughness and elasticity, which will produce a certain swing when encountering an earthquake, which can effectively reduce the earthquake strength without serious collapse; From the perspective of building span, steel structure buildings have super seismic resistance of large span space; In terms of waterproofing, this kind of building has a strong waterproof performance to prevent rainwater from flowing back; In terms of use cost, it has good thermal insulation performance, can maintain indoor temperature for a long time, reduce the cost of refrigeration and heating, and durable structural members can minimize the maintenance cost; From the perspective of fire resistance, since the maximum temperature that the steel can withstand is 600 ℃, it will melt when it reaches and exceeds 600 ℃, and the surface of the steel structure is coated with a fireproof layer, which can withstand three hours of high temperature combustion. The fire resistance is extremely excellent.



The advantages of steel structure office buildings, circular economy and sustainable development have been recognized by the society and gradually expanded the market scope, but the support of national industrial policies and the attention of competent departments are far from enough. At present, the national development force is weak, and the independent innovation is poor. There are many problems restricting the development of steel structure office buildings, which to some extent reflects many problems in the development of steel structures, in terms of economic policies;

1. It is a strategic national policy to use more steel and steel structures for resource utilization, and expenditure should be encouraged and strengthened. However, the enterprise has no short-term benefit return, which is difficult to be popularized and applied.

2. The concept of long-term planned economy is backward, the product is not refined enough, and the added value and development are strengthened. The foundation supporting the steel structure is far from strong enough.



3. The largest market, namely, the construction industry, is relatively backward. There are too many stakeholders in housing construction development, and the design and use are deepening, but the protection of rights, responsibilities and private rights is insufficient. Finally, the rapid development of the steel structure industry is conducive to the stable development of the national economy. We hope that steel suppliers, steel enterprises and steel structure manufacturing enterprises can jointly form an industrial alliance to make the steel structure industry bigger and stronger. Only when the manufacturing industry is strong can the country become strong.
