Research On Design Strategy Of High-density Multi-storey Residential Building Combination Based On Winter Windproof In Bohai Rim Region

The research content of this article originates from "a Key Project of the 13 th Five-Year National R&D Program" : An environmentally friendly building construction system that inherits the traditional architectural context of coastal economically developed areas.Since the Economic Reform and open up,commercial housing has developed more than forty years.People's requirements of housing are no longer limited to the building quality of the housing,the environmental quality of the housing is also an important standard for people to evaluate modern housing.As an important part of the micro-environment in the residential area,the architectural wind environment has become an increasingly important evaluation factor.The significance of this study is to analyze the advantages and disadvantages of the outdoor wind environment and indoor windproof in combination with architecture design,and have a clearer understanding of the relationship between the variables of architecture design and the architectural wind environment in order to provide a certain design method guidance for the actual design.The article takes the high-density multi-storey residential buildings in Bohai Rim Region as the research object,and takes windproof in winter as the starting point to analyze the wind environment of the most common determinant type and enclosed type in the Bohai Rim Region.And the study is divided into three levels: building group,building combination and building monomer according to scale.Through the simulation of the AIRPAK,explore the influence of various architectural design variables on the wind environment and get the best design strategy.The introduction part of this article introduces the research background,research purpose,research content and article structure.The second chapter first analyzes the characteristics of the winter wind environment in the Bohai Rim Region and introduces the wind environment evaluation indicators,then introduces the main layout patterns of the residential buildings in the Bohai Rim region,and finally makes statistics on the scale of various multi-storey residential buildings in the region.And the simulation provides a reference basis.Chapters 3 to 5 respectively study the outdoor wind environment and indoor windproof at three levels of building groups,building combinations and building monomers under the influence of the dominant wind direction in the Bohai Rim Region in winter.Each of the three chapters first introduces the simulation conditions,delimites the simulation range,and then analyzes the design variables that affect the wind environment of the residential area,and then conducts a wind environment numerical simulation experiment on the basic physical model through the control method.Different design variables of multi-storey dwellings can be used to derive the change regular pattern of the wind environment in the residential area,and analyze the effect and degree of each variable on the outdoor wind environment and the indoor windproof through the changes of the wind speed ratio,wind pressure difference and other parameters,and obtain the most advantageous architectue design strategy.The sixth chapter carries out the layout design of the residential area through the design strategy summarized above,and verifies its rationality.The conclusion part summarizes the full text,and points out the factors and shortcomings that are ignored in the study.The whole thesis contains about 40005 words,119 pictures and charts.
