Although the Japanese earthquake serious threat to lives and property, but according to the present situation, the Japanese architecture are built of blocks of the displacement, some destroyed, as it is not collapsed, so little direct casualties. China earthquake damage and its not the same language, and some building materials can be recycled. As a result, industry experts, the Japanese earthquake on the export of building materials industry will not have much direct relevance. Conversely, Chinese and Japanese housing construction in the performance comparison of different disasters, but it can on our awareness of building a positive impact shock.
Building great stress in Japan
As earthquakes, in almost every house building, the number of seismic performance of the best in Japan. Structure, compound wall and so much stress. First, Japan earthquake performance of buildings generally use high steel structure, wood structure and a small amount of the reinforced concrete structure. Japan in 1960 to promote full steel construction. According to incomplete statistics, the Japanese started building area of steel in 1960 accounting for 13% to 40% now, residential prefabricated steel accounting for up to 71%.
Japanese high-rise buildings are generally more earthquake resistant steel used, because steel has a certain toughness, excellent seismic performance, steel beams, steel columns composed of flexible frame can resist earthquakes octave. And there are light weight steel construction, and small size. In the high intensity earthquake zone, if the half to reduce weight, the equivalent of reducing the seismic intensity was. According to estimates, medium-building steel structure, the structure to reduce weight by about a third earthquake can be reduced by 30% to 40%, the load per unit area on the ground can be reduced by 25% or more. Steel buildings as light weight, the inertia force is small, the earthquake damage to its structural role is small, so steel construction in earthquake-prone countries, Japan and other widely used.
Family homes in Japan are usually wooden structures, the false appearance of a modern brick veneer, wood and wood in ancient China between the tenon with a similar connection, this structure has some ductility and tension, the general earthquake does not collapse. Secondly, the Japanese house building materials are lightweight materials, under normal circumstances, when you hit the body fall, will not cause serious injuries. In addition, the Japanese has a habit of furniture will be fixed in the housing, it can avoid the damage caused by the earthquake.
Steel and composite wall or benefit manufacturers
Currently, the only earthquakes, tsunamis, had a strong influence on Japan, and explosion caused by nuclear radiation leakage to further expand the impact of disasters, mainly for steel building structures in Japan, do not rule out the domestic steel manufacturers to directly export through state aid or assistance to people in Japan reconstruction possible.
Japans residential compound wall is commonly used raw materials imported from China, because China and other supporting materials, wall materials, technology is not mature, so the production and processing in the country completed. The impact of disasters but also the further spread of Japanese companies may be looking for the future of Chinas building materials manufacturer for production. Concern is that this strong earthquakes in Japan has the potential to increase its level of all the buildings of the earthquake, so companies will benefit greatly reinforced housing, which will include steel manufacturers, alternative materials and alloy materials, damping device manufacturers .
Will become the development trend of earthquake-resistant construction
Building materials businesses to benefit from Japans post-disaster reconstruction, only short-term gains, but a more thought-provoking is the sense of whether the construction of earthquake strengthening.
In China, research materials, earthquake-resistant construction, and shock are separate enterprises or small industry that is, there is no specialized research authority. Building standards in China, not even the relevant requirements.
In contrast with the Japanese earthquake, the Chinese Yunnan Dehong Yingjiang of the recent 5.8 earthquake, the county supermarkets, hotels and many houses collapsed, the city most of the walls collapsed. After the earthquake, many buildings along the cracks in the wall Yingjiang, earthquakes cause most of the old city Yingjiang housing collapse. Directly to the bottom of the collapse of many houses, a three-story supermarket on the first floor completely collapsed, the original second floor into the first floor.
Industry experts said that from a major earthquake on infrastructure projects and building damage of view, or cause frequent earthquakes thinking of building a more solid and secure. From, steel construction, integrated housing future will increasingly favor more domestic construction.
