Advantages and disadvantages of steel structure

The steel structure has the characteristics of high strength, light weight, good seismic performance, small size of structural members and high industrialization degree. In addition, the steel structure is a recyclable green material, so the steel structure residential system will be a very promising residential system.

Advantages of steel structure:

1) High strength, light weight. Reducing the weight of the structure can reduce the function of earthquake disaster, and then reduce the internal force of the structure and reduce the foundation cost, especially in the soft soil area. In addition, the components are lightweight and easy to transport and install.

2) Uniform material, good plasticity, good toughness, good seismic performance. Steel has good toughness, so the steel structure should have vibration load. Steel structures in earthquake-stricken areas are more earthquake-resistant than engineering structures of other materials. Generally speaking, steel structure is a structure that is less damaged in an earthquake disaster.

3) Simple manufacturing, high degree of industrialization, short construction period; Generally speaking, steel components are manufactured in the production plant, with high precision, stable quality and low labor intensity.

4) Small section and large effective space; In the case of the same beam height, the opening of the steel structure is 50% larger than that of the concrete structure, which better meets the requirements of large opening and flexible division of the building.

5) Energy saving and environmental protection materials. The built steel structure is also relatively easy to transform and strengthen, and the steel structure connected by bolts can be dismantled according to needs, which is also conducive to environmental protection.

Steel structure defects:

1) The heat resistance of steel is good, but the fire resistance is poor.

2) Steel corrosion resistance is poor, should take appropriate protective measures.
