Multilayer Cold-formed Steel Housing Analysis Of Wind-induced Response And Wind Resistance Measures

Storm is more frequent occur in our country. Hurricane caused a lot of damage to houses and injuries. It causes enormous damage to buildings. It makes the country losing a lot of money. So it is necessary to research the wind characteristics of building and failure characteristics of building and comfort of structure. Only in this way, we can reduce injuries and collapsed of houses. We can build safe and reliable of structure. Multilayer cold-formed steel has light weight and low damping ratio and large deformation and large natural period. We can think it is like a concrete tall building. Fluctuating wind, this is close to structural vibration period close, can not be ignored its dynamic effects. Wind load as one of the primary structure level control loads, it control structural safety and comfortable. When design structure of building,we have to consider the impact of wind load. To research multi-layer cold-formed steel housing wind-induced response and comfort issues under wind load, this paper carried out the following work.Firstly, using consider space and time linear correlation autoregressive filter method(AR law). Utilize matlab to achieve fluctuating wind. The wind speed is converted to wind pressure, which is generated by the Bernoulli equation.Secondly, to verify wind-induced response of the structure through compare papers values, we can verify the reasonableness of self procedures. Combination with Huang Zhiguang’s cold-formed steel experimental research, and he is graduated from Xi’an University of Architecture and Technology. Multilayer cold-formed steel housing modeling tools have been validated.Thirdly, establish multi-layer cold-formed steel house overall model, which contain five layers and six layers and seven layers. Obtained structure’s displacement and acceleration response under different pressure, which contain 0.3 k N/m2 and 0.5 k N/m2 and 0.7 k N/m2 and 0.9 k N/m2 and 1.1 k N/m2. Combine with the high-rise buildings technical specification to study the structure’s limits of displacement and acceleration under wind load. Combined with China’s building structural load specifications, assess Comfortable problems of multi-cold-formed steel housing.Fourthly, According to comfortable of national standards and well-known comfortable test results, access multilayer cold-formed steel housing comfortable issues, which is under wind loads. And raised wind comfortable measures, comparing the efficiency measures of measures. I hope to promote the further development of multilayer cold-formed steel housing.
