Reinforcement Technology Of Steel Structure Damage

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 section of steel structure weaken. Certainly, other illegal use and operation will lead to damage.

There are three reinforcement method to steel structure. They are section reinforcement, change the calculation diagram and prestressed cable method. Section reinforcement is using the steel to reinforcement in local or along the member length. The method of changing calculation diagram is that adding support, adjust load distribution,reduce stress levels, decrease the stress peak. Prestressed cable method is that strengthening weak links with high-strength cable or improving the whole structure bearing capacity, rigidity and stability.

Once the earthquake occurred, we must first maintain a clear, cool headed and determine shock condition promptly. Don’t jump off building in panic. This is very important. Besides you can hidden under solid furniture or corner. Certainly you can also transferred to the kitchen which has small hall and many load-bearing walls or even toilet. Because these places has strong combining power, especially the pipe has good support force after some treatment, and seismic coefficient is larger.

Steel Structure Of Bird Nest In China

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 formed residential industrialization of steel structural system in Finland, Sweden, Denmark and France. The requirements to high-rise and long-span construction are also getting higher and higher because of human cultural life continues to improve.

Steel structure has the advantages of light weight, high strength and fast construction. So it is very ideal that adopt steel structure for high and long span, especially for super high and super long span. At present, the most highest and biggest constructions all adopt steel structure in the world. By the way, the Olympic Games venues also mostly use steel structure.

Bird nest which made by China steel structure manufacturer is regarded as main stadium in Beijing Olympic Games. Bird nest is a venues with largest investment and technological content. It is also a key project which is in highest concern, highest technical content and most difficult in the Olympic Games projects. Bird nest steel structure are all completed with welding and without any screw. Stell structure of bird nest has been coated antirust paint with five layers. The antirust paint has functions of anti-corrosion, moisture-proof and fireproof. Besides the bird nest has two two layer of the film. The upper lay is ETFE and the lower one is EPFT. These can prevent audience in bird nest from rain and sun.

Economy H Section Steel

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. Assembled into components can save welding and riveting work. H section steel is often used for the large building which needs big bearing capacity and good stability of section. Such as factory buildings and high-rise buildings. Certainly H section steel is also suitable for bridge, ship, lifting transport machinery, equipment foundation, support, foundation pile.

H section steel is belong to efficient and economic cutting surface profile. It can make steel in higher performance and improve the bearing capacity due to its reasonable section shape. Flange of H section steel is widened, the inner and outer surface are both parallel. This can convenient to the bolt that connect with other members. Its size is reasonable and model is complete. So it is also easy to chosen by designers.

Which Building Is Most Safe During Earthquake

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 different conditions.
In school teachers and leaders should be calm and resolute when earthquake. The area which has medium and long-term earthquake prediction should combine with the teaching activities. Teachers had better tell some knowledge about earthquake to students. And teachers also must arrange students to transfer, evacuation routes and sites before earthquake. Calmly directing students evacuate in order. In the durable and safe houses people can escape under the desk and podium. Students in teaching building can go to the small hall and with a pipeline support room. Don't let students run or jump off building.

When the earthquake occurred, glass of high-rise buildings, advertising signs and neon light frame may fall wounding. So people had better put their leather bags or soft things on their head. If there is nothing soft things, you can put your hand on head to protect. Leave the poles and the wall, run to a broader regional to escape.

Design In Steel Structure Manufacturer

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 characteristics of different structure forms should be take into account in structure selection. In the workshop, You can consider to give up the door frame and use the rack when a larger hanging mobile load or large range.  Roof curve should be helpful for snow slide in the area with big snow. The layout of support in the frame will have better economy than simple frame with rigid joint. And you can choose the component that suspension or the cable membrane structure system in the roof cover larger span of building.
Design in high-rise steel structure manufacture often use steel concrete composite structure. In the high earthquake intensity or very irregular high-rise, you should not only for the economy to select against seismic core barrel and the frame form. You had better choose peripheral giant SRC column, core for braced frame structure system.

Environmental Potential To Steel Structures Building

With the development of awareness of environmental protection to people, more and more buildings start to use steel building structure which could save energy. Environmental protection of steel structure can not only bring economic benefits, but also make contributions to the social problems of environment and resources.
Demand for resources and products in the construction industry is largest. While on the natural resources, the destruction of the ecological environment and the impact is the biggest. So people usually should take a long time but also very carefully in order to make the decision when building houses. The environmental protection of steel structure now has been affectionately known as the green building in twenty-first Century. This reputation is not weakness lends wings to rumours. It is obtained by  the unique advantage of environmental protection of steel structure. Its recycling use building structure is not only in line with the development of energy conservation policy, but also satisfy with the sustained and healthy economic development.
Next we will introduce potential to the steel structure. Construction of environmental protection steel house is lighter than the traditional housing weight. And its using area can also increased about five percent. This is a big advantage of lightweight and high strength. Certainly steel structure has good performance of the seismic resistant. Due to some components are finished in factory, so it will reduce the work of site construction and shorten the working time. This is very in line with the requirements of industrialization. Besides that steel structure also could be used recyclable.
