What happens to the light steel house during an earthquake? -wellcamp light steel villa manufacturers
What does the light steel villa keel look like during an earthquake? Lateral force of light steel keel house——The displacement relationship has strong nonlinearity, and its hysteresis curve also has strong pinch. In the seismic fortification area, the light steel keel house can maintain the integrity of the structural function under the action of the design earthquake; under the action of the rare earthquake, the structure will not collapse. The reason why the light steel structure has a good seismic effect is that the main principle comes from the skin effect. The so-called skin effect refers to covering materials in the form of roof panels and wall panels on the surface of the building, and using the stiffness of the material itself to strengthen the overall strength of the building. It mainly covers the metal plate on the longitudinal and transverse ribs to form a ribbed thin shell. The ribs and the thin shell work together to make the skin exert a huge tensile, compressive and shear resistance effect in its plane. , 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, which makes it have the characteristics of small self-weight, strong deformation resistance, and not easy to collapse. When an earthquake occurs, there will be up and down or left and right vibrations, and 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 the shaking of the ground. Protect personal and property safety. At the same time, the excellent seismic resistance of the light steel structure is also reflected in the ductility of the building, and the area at the plastic hinge is subjected to vibration and deformation, thereby greatly reducing the impact of the building structure on the earthquake. Therefore, the use of ductile light steel structures can reduce the requirements for building bearing capacity, in other words, ductile structures can withstand earthquakes through their own deformation. 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.
