Steel corrosion not only make the sectional area decreased, but also reduce its performance and even scrapped. Besides if it has been appeared corrosion pit, that will make stress concentration and accelerate structural damage. Especially impact load and cyclic alternating loads, it will appear phenomenon of corrosion fatigue. At this time, the fatigue strength of the steel will be reduced greatly, and even the emergence of brittle fracture. According to the corrosion mechanism, steel corrosion ...

As we all known, steel structure material is not easy to be rust, it is fatal if the steel structure rust. It may lead to seriously consequence. There are many descaling method for steel structures. Such as manual descaling, sand or shot blasting, acid pickling and others. Manual descaling is always in low efficiency and can not derusting throughly. It has an influence on the adhesion of the paint and the structure is easy to rust. Some light steel structures with small round bar and angle steel ...

At present, light steel structure is developed quickly in China. Compared to the traditional reinforced concrete structure and ordinary steel structure, light steel structure has many advantages. Light weight is the significant features of light steel structure. Light steel structure is also in high degree of industrialization. Components of cold-formed steel, pressure plate, connecting pieces are automation. So it is always in high efficiency and good quality.As we all known, light steel struct ...

Recent years, steel structure rise quickly as a green cycle and low carbon building in China. Some expert point that this will make a large market to steel structure. At the same time, it will put forward new and higher requirements to steel supplier. At present, there is little species and bad quality stability in China. Many steel structure manufacture pay little attention on steel supplying. So they should find new varieties of steel in order to meet the requirement of steel market.Carbon emi ...

The important structures which are easy to occur load change adopt hyperstatic structure, such as bridge, truss, sluice gate and missile launchers. Because they have redundant bar which can prevent that a member instability cause the overall instability.Steel structure instability can be divided into two categories. They are overall buckling and local buckling. The overall instability mostly caused by partial instability. When the compression part or bending parts of the slenderness ratio exceed ...

If there are some damages in steel structure, we need solve problem in time. There are five factors that caused steel structure damage. Firstly, the load changed, the service extended, rules and regulations changed. Secondly, structure deformation,twist,disability or depression with various accidents. And it also section weaken, rod warping, connection cracking. Thirdly, component or connection deformation, cracking and warping which caused by temperature effects. Chemical corrosion make the sec ...

Steel structure is very popular in developed country. There is very broad prospects of development to China steel structure manufacturer. Generally speaking, the beam use H type steel. And connected nodes use high-strength bolts or welding. At present steel structure housing is popular in the industrial developed countries. Fireproof material mainly adopts the fireproof paint or fire board coating. There are about 50% residential building with steel frame in Japan and 20% in America. It has been ...

H section steel is a kind of new economy construction steel. Section shape of H section steel is economic and reasonable. It has good mechanical properties. Each point extended uniform and internal stress is small when rolling. Compared to the ordinary I-steel, it has the advantages of big section modulus, light weight and saving metal. H section steel can make the building structure reduce about 30% to 40%. The inner and outer side of the leg are in parallel and leg end is a right angle. Assemb ...

Generally speaking seismic capacity of building has relationship with design. Steel structure building and reinforced concrete structure have more strong seismic capacity. But brick concrete structure has weaker seismic capacity. So there is always with structural column and the ring beam.You must go to the nearest and escape when earthquake. Quickly evacuated to a safe place, it is a better way to contingency protection after the earthquake. It means that making different measures according to ...

Steel structure design is very important, so we must be careful in designing. Steel structure is usually used in the structure such as high-rise buildings, large span, complex shape, load or the crane load, with large vibration, can activities or frequent dismounting structure. Intuitive to say, building, gymnasium, opera house, bridge, tower, sculpture, barn, factories, residential, mountain and temporary buildings and so on. These are consistent with characteristic of steel structure. The char ...
