On the 8th to the 9th of last month, the annual work of the Steel Structure Expert Committee of China Construction Metal Structure Association was held in Wuhan. At the meeting, three Chinese Academy of Engineering academics - Professor Shen Zuyan from Tongji University, Professor Dong Shilin from Zhejiang University and Professor Ma Kejian from Guizhou University, jointly proposed , Vigorously develop the steel structure building to resolve the current serious excess steel production capacity.
Shen Zuyan "Light, fast, good, provincial" to describe the characteristics of steel construction, he believes that steel construction is most suitable for building industrial construction. Dong Shilin brought his latest research: a "hexagonal tetrahedron unit composed of" spherical reticular shell ", to facilitate industrial production prefabricated. Ma Jianjie is the scene to promote multi-storey long-span "grid structure", mainly for assembly-type construction.
According to reports, Bacheng components of steel construction can be processed at the factory, easy to remove, some products and materials can be repeated, recycling, is an important representative of green building. Compared with traditional concrete buildings, the deadweight is reduced by 40%, the construction efficiency is increased by 4 times, the construction period is shortened by 1/3, the carbon emission is reduced by 35%, and the room rate is increased by 5% or more, which is more common in developed countries.
Statistics show that in the recent five years, China's annual steel construction steel consumption 30 million to 50 million tons, accounting for about 5% of steel production, the proportion of 45% with the United States, Japan 28%, Germany 22% compared to significantly low. The academicians believe that by vigorously promoting and developing steel structures, it can not only solve the overcapacity in the steel industry, but also promote the industrialization of buildings and transform and upgrade the traditional industries.
