Study On Structural Framework And Structure Of Light Steel And Wood Composite Structures ——A Case Study Of Public Area Of Jinniu Lake Yuan She Hotel, Nanjing

With the accumulation of practical experience and theoretical development of human production activities,the materials,construction technology and construction used in construction engineering practice all over the world have obtained great innovation and progress.Wood as the most traditional construction material in today’s construction market is still in the advantages of high mechanical properties,low cost covers most residential or public building materials,but with the increase of height and span of building,the usage of lumber also doubled,but sometimes the stress of the wood ceiling is still unable to meet the needs of large space building,Moreover,the reduction of forest area and the deterioration of ecological environment also force us to focus on the development of new materials or new technologies.As a kind of light and strong material,steel came into people’s field of vision during the industrial revolution.After more than two hundred years of development,steel structure building has been relatively mature,steel structure is gradually widely used in western large-span buildings.However,the steel structure also has some defects caused by material properties.After people’s research,steel and wood these two kinds of strong material light material can be combined with each other,steel and wood combination of the structure form can make up for the lack of pure steel structure and pure wood structure performance,improve the overall structure of the stiffness,strength,toughness and flexibility,but also to meet the large-span large-span space bearing capacity requirements.In some construction practices at home and abroad,steel-wood composite structure is gradually applied in large span space,light buildings and some public buildings.Therefore,the author hopes to study the construction system of the steel-wood composite structure,learn the strategy and experience from it and put it into practice.The introduction part of this paper firstly defines the concept and scope of the research focus of this paper,and introduces the research status at home and abroad,the basic ideas and framework of the research.The second chapter summarizes and compares the characteristics of wood structure and steel structure,and draws out the types and forms of steel and wood composite structure based on the above.The third chapter introduces the representative light construction cases of steel and wood composite structure at home and abroad,and summarizes the specific design problems by combining steel and wood with the logic of construction in the face of different construction environment and space function requirements.The fourth chapter introduces the actual project of public area of Jinniu Lake Yuan Hotel in Nanjing which the author participated in the tutor’s studio.The fifth chapter takes the project as an example,according to the project needs to solve the problem,uses the construction thinking logic to choose different structure skeleton,applies the corresponding steel and wood composite structure or component,and studies the construction method.The sixth chapter is the conclusion of this paper,which makes a reflection and summary of the whole paper,and points out the regrets and deficiencies in the research design of this paper.The whole thesis contains about 28896 words,209 pictures and charts.
