Rural self-built houses|Henan Light steel structure houses At the current stage of the development of light steel villas, most countries in the world have the same residential villa construction model as China's rural areas, that is, rural self-built houses. The difference is that we are still building brick-concrete engineering buildings with red bricks, and these engineering buildings cannot resist earthquakes or heat insulation. In foreign countries, wood, prefabricated reinforced concrete, steel, light steel and other building materials have completely replaced red bricks, and prefabricated engineering building systems have also replaced on-site operations. It is very environmentally friendly, fast to build, and has thermal insulation and noise reduction. At the same time, such energy-saving and environmentally friendly materials also leave more and more development space for the future of mankind. According to a survey conducted in 2013, traditional brick-concrete engineering buildings generate hundreds of millions of tons of construction waste every year, and traditional residential energy consumption accounts for 27.5% of the total energy consumption of social terminals. This is also a typical extensive development model and an important factor in smoke generation. one of the reasons. The light steel structure house is a residential building with the cold-formed thin-walled steel structure feature as the load-bearing frame and the lightweight wall material as the envelope structure. The emission of light steel housing construction is about 480 kg/m2, which is 35% lower than the carbon emission of traditional concrete of 740.6 kg/m2. In addition, due to the construction of the assembly project, the noise, waste water discharge and dust pollution on the construction site are reduced. Reduce sand mining and construction waste emissions. When the building was demolished, the recycling rate of the main structural materials of the light steel building was over 90%, which was about 60% lower than the traditional concrete waste discharge. It is conducive to protecting the environment and creating a new era of engineering and construction civilization. The light steel villa is the most energy-saving and environmentally friendly building structure in the current residential construction field, and the appearance is also very beautiful. Many public buildings are actively adopting this architectural form. If the environmental protection effects of prefabricated engineering buildings and light steel structure engineering buildings are still easily understood and recognized by everyone, what are the characteristics of such engineering buildings compared with traditional Chinese buildings, apart from their outstanding energy-saving effects? Can you withstand the wind? Can you build tall buildings? In fact, there is no need to worry about these conditions. As a new type of structural feature system, light steel villa keel residential system has its own dynamic characteristics: the hysteretic curve of structural features under the action of horizontal force has a strong shrinkage effect. The light steel villa keel is light in weight. Under the action of the same intensity of earthquake disaster, the light steel structure has less stress than the ordinary concrete structure and ordinary steel structure, and can generally work within the elastic range under the action of the designed earthquake disaster. The lateral force-displacement relationship of the light steel frame structure has a strong nonlinearity, and its hysteresis curve also has a strong pinch property. In earthquake-resistant areas, light steel frame engineering buildings can maintain the consistency of structural characteristics under design earthquake disasters. Under the action of rare earthquake disasters, the structural features do not collapse. The main reason why the light-weight steel structure has excellent seismic effect comes from the skin effect. The so-called skin effect usually refers to covering the material on the surface layer of the building in the form of roof panels and wall panels, making full use of the strength and stiffness of the material itself to strengthen the overall strength of the building. It is mainly to cover the longitudinal and transverse ribs with metal plates to form a ribbed thin shell. The joint action of the ribs and the thin shell promotes the skin to fully exert its huge tensile, compressive and shear resistance effects in its plane. The supporting role of the skin can continue to maintain good stability. The skin structure has a large bearing capacity, but its own weight is very light. The light steel structure makes good use of the skin effect, and has the characteristics of small dead weight, strong deformation resistance and not easy to collapse. When an earthquake occurs, there will be up and down or left and right vibrations. The light steel structure connected by fasteners forms a stable box shape, which will not cause the floor to fall or the wall to collapse due to ground vibration, effectively protecting personal and property safety. At the same time, the excellent seismic performance of the light steel structure is also reflected in the ductility of the building. The plastic zone is prone to vibration deformation, thereby greatly reducing the impact of earthquakes on buildings. In earthquake resistance, structural ductility is very important and has the following functions: to withstand and alleviate the effect of accidental factors. During the use of the structure, sudden and accidental effects will be encountered, such as thermal expansion and contraction caused by large temperature changes, accidental overloading, and so on. These factors trigger safety reserves when the structure is created. Good for earthquake resistance. When an earthquake occurs, the plastic hinge area of the light steel structure can absorb and consume seismic energy through deformation, reduce the stiffness of the structure, and reduce the effect of the earthquake on the building.
