Difference between steel structure house and wood structure house

一、经济方面

1. Economic aspect

钢结构住宅的经济性是阻碍钢结构住宅发展的最大障碍，根据我们国家现有的钢结构发展水平，钢结构住宅的土建造价要比钢筋混凝土住宅高10%~20%左右，但钢结构住宅较混凝土结构在基础造价上可节约30％，且钢结构住宅的得房率较混凝土住宅高7％～10％，此外钢结构住宅的施工工期也可减少约30％。

The economy of steel structure housing is the biggest obstacle to the development of steel structure housing. According to the existing development level of steel structure in our country, the construction cost of the steel structure residence is about 10%~20% higher than that of the reinforced concrete residence, but the steel structure housing can save 30% of the concrete structure on the base cost, and the steel structure residence is obtained. The room rate is 7% to 10% higher than that of the concrete residence, and the construction period of the steel structure residence can also be reduced by about 30%.

就目前国内进口的木结构房屋而言，成本价一般要在4000~8000人民币每平方米，可见要远远高于普通的钢筋混凝土和砌体房屋的造价，这对于一般开发商和普通用户都是难以接受。但是，随着我国经济的高速发展，高收入群体的逐步形成和壮大，他们消费意思的成熟和生活品位的提升，这种“温暖”的，与大自然容融为一体的绿色环保型住房肯定是有市场的。

As far as the current domestic imported wood structure houses are concerned, the cost price is generally at 4000~8000 RMB per square meter, which is far higher than the cost of ordinary reinforced concrete and masonry buildings, which is difficult to accept for the general developers and ordinary users. However, with the rapid development of China's economy, the gradual formation and expansion of high income groups, the maturity of their consumption meaning and the promotion of the quality of life, this kind of "warm", green and environment-friendly housing, which is integrated with nature, is certainly a market.

钢结构住宅与木结构房屋造价相对于砖混结构来说相对较高，一般消费群体短期内接受的可能性不大，站到环保节能的角度上，钢结构住宅能够充分再利用占有很强的优势，据调查表明，随着国民生活水平的提高，汽车的持有量在成倍递增，随之而来报废汽车的回收问题将越来越突出。钢结构的循环利用也许是解决这个问题的有效途径之一。

The cost of steel structure housing and wood structure is relatively high relative to the brick concrete structure, and the possibility of accepting in the short term is not very likely. From the angle of environmental protection and energy saving, the steel structure housing can make full use of a strong advantage. According to the investigation, it is shown that with the improvement of the living standard of the country and the people, the car is held. The volume is increasing exponentially, and the problem of the recovery of scrapped cars will become more and more prominent. Recycling of steel structure may be one of the effective ways to solve this problem.

一幢木结构建筑则需要耗费树龄大约10年左右的树木，大量木结构房屋的建造有悖于节能环保的初衷，危害在此不做赘述。

A wooden building needs to spend about 10 years old trees, and a large number of wood - structured houses are contrary to the original intention of energy conservation and environmental protection.

二、抗震性能

Two, seismic performance

进入21世纪以来，大自然开始用一系列的自我保护措施来提醒人类对自然资源的不节制开发和浪费。灾难仿佛悬在人类头顶的利刃，似乎相隔很远，却又近在身边。

Since the beginning of 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 seems to hang on the edge of human head. It seems to be far away from each other but close to it.

好的建筑，除了宜居之外，安全的重要性不言而喻。

Good buildings, apart from livable, the importance of safety is self-evident.

钢结构具有良好的延展性，可以将地震波的能耗抵消掉。钢材基本上属各向同性材料，扛拉、抗压、扛剪强度均很高，而且具有良好的延展性，特别是钢结构凭着自己特有的高延展性减轻了地震反应。钢结构还可以看作比较理想的弹塑性结构，可以通过结构的塑性变形吸收和消耗地震输入能量，从而具有较高的抵抗强烈地震的能力。钢结构相对于其他结构自重轻，这也大大减轻了地震作用的影响。

The steel structure has good ductility, which can eliminate the energy consumption of seismic waves. The steel is basically isotropic, with high tensile, compressive and shear strength, and has good ductility. Especially, the steel structure with its own high ductility reduces the seismic response. The steel structure can also be considered as an ideal elastoplastic structure, which can absorb and consume seismic input energy through the plastic deformation of the structure, thus having a high ability to resist strong earthquakes. The steel structure is lighter than other structures, which greatly reduces the impact of earthquake.

木结构也有一定的抗震作用，但是因为木结构建筑的层数一般较低，不适应越来越紧张的土地资源，达不到高层建筑的要求。

Wood structure also has a certain seismic effect, but because the number of wood structures is generally low, it is not suitable for more and more tense land resources, which can not meet the requirements of high-rise buildings.

钢结构住宅与木结构房屋有一定的相似性，站在长远发展的角度上，钢结构住宅的推广和广泛使用才是我们未来的可行性选择。

There is a certain similarity between the steel structure housing and the wood structure housing. In the long-term development point of view, the popularization and extensive use of the steel structure housing is our future feasibility choice.
