Steel building will continue to be extended in recent years, the world earthquake, more and more development of steel building is the focus of the government to encourage the full construction steel housing. Structure or technology or steel welders, the last to be implemented in the use of functions, let the old common people visible, tangible, lived contentedly. Reinforced concrete, steel is still the main material of Chinese architecture, and in some areas even see brick and concrete building. Japan, the US steel housing, according to a relatively high rate, partly because they have strong economic strength; on the other hand is due to compression of the steel structure, good tensile strength, earthquake or other natural disaster hit when not will produce brittle fracture, while the concrete structure will produce brittle fracture, and can not be reused. In fact, the structure is for construction services, the use of the function is the construction of most concern to consumers. To promote the steel construction, it is necessary to improve the use of functional steel construction steel construction, steel housing can not let the impression is cold. Old common people do not care whether the steel housing for industrial production, they are more concerned with building security and quiet nature. From the actual situation in China, the promotion of post-disaster reconstruction in steel residential recovery of the local economy is no pulling power of large concrete building, due to the steel housing is factory produced, assembled at the construction site, you can save a lot of labor. A lot of the old common people have not been exposed steel structure, coupled with propaganda is not, leading them to think that steel residential home is not pleasant. Some steel housing demonstration projects all around the building structure to work on, this is wrong. Japan, the United States, building seismic scale higher than ours, which is determined by the state power. Steel construction makes the most important strengths - good seismic performance - stand out. In Japan, the United States and other Western countries, the total residential steel buildings as high as 50%, while China's steel housing is still in the pilot stage of promotion. Steel production in the construction, assembly process, the structure of the situation envisaged node distribution practices and weld steel construction will have a significant impact. Because steel complex form. Impossible as welding deformation towers, tanks and other equipment have a certain discipline, can perhaps be calculated by calculating the amount of deformation, take another way to moderation before 尔后提. Steel deformation no discipline, only empirically reasonable arrangements welding sequence and welding shrinkage. Such as steel construction in CBL-III type furnace structure, because the furnace wall weld large and concentrated, resulting in serious shorten furnace size, if not reserved in advance extend margin, the chamber size will be significantly less than the design dimensions.
