Differences between steel structure residence and wood structure housing

 With the step-by-step promotion of energy conservation and emission reduction requirements, buildings have also been labeled as environmental protection. The materials for building livable buildings have launched a fierce competition between steel structure and wood structure. Here we briefly analyze the differences between steel structure houses and wood structure houses:

The economy of steel structure residence is the biggest obstacle to the development of steel structure residence. According to the existing development level of steel structure, the civil construction cost of steel structure residence is about 10% ~ 20% higher than that of reinforced concrete residence. However, compared with concrete structure, steel structure residence can save 30% in foundation cost. And the occupancy rate of steel structure residence is 7% ~ 10% higher than that of concrete residence. In addition, the construction period of steel structure residence can also be reduced by about 30%.

The cost of steel structure housing and wood structure housing is relatively high compared with brick concrete structure, which is unlikely to be accepted by general consumer groups in the short term. From the perspective of environmental protection and energy conservation, steel structure housing can be fully reused and has a strong advantage.

A wood structure building needs trees with a tree age of about 10 years. The construction of a large number of wood structure houses is contrary to the original intention of energy conservation and environmental protection.

Seismic performance

Since entering the 21st century, nature has begun to use a series of self-protection measures to remind mankind of the uncontrolled development and waste of natural resources. Disaster is like a sharp blade hanging over the head of mankind. It seems to be far away, but close by.

In addition to being livable, the importance of safety is self-evident.

The steel structure has good ductility, which can offset the energy consumption of seismic waves. Steel is basically an isotropic material with high tensile, compressive and shear strength and good ductility. In particular, the steel structure reduces the seismic response with its unique high ductility.

Steel structure can also be regarded as an ideal elastic-plastic structure, which can absorb and consume seismic input energy through the plastic deformation of the structure, so it has a high ability to resist strong earthquake. Compared with other structures, the weight of steel structure is light, which also greatly reduces the impact of earthquake.

Wood structure also has a certain anti-seismic effect, but because the number of floors of wood structure buildings is generally low, it can not adapt to the increasingly tense land resources and can not meet the requirements of high-rise buildings.

There are certain similarities between steel structure housing and wood structure housing. From the perspective of long-term development, the promotion and wide use of steel structure housing is our feasible choice in the future.
