Research On Structural Design And Construction Technology Of Inclined Closure High-rise Buildings

Inclined closure high-rise building is a kind of building with special architectural form and complex architectural space.Firstly,this paper takes the actual case as the research object,analyses the architectural morphological and spatial characteristics of inclined closure high-rise buildings,and points out that modern high-rise buildings can effectively improve the physical environment of buildings and enrich the shape of high-rise buildings by adopting inclined and retracted forms;The aerial corridor bridge and roof platform can connect the isolated buildings,relieve the pressure of ground traffic,enhance the landscape and sociality of urban buildings,and provide public community communication space for people;"City living room" is a high-density building area to create high-quality public space,enhance the vitality of the city.Therefore,this special form of building is an effective response strategy in the high-density environment of the city.In view of the fact that there are no actual cases of inclined closure high-rise buildings built at home and abroad.Whether the structural design and construction technology of this new high-rise building can be solved or not is very important for its real implementation.Secondly,the mechanical knowledge,basic concepts,basic requirements,commonly used classification and structural technology of existing high-rise buildings are described in detail;the structural design of a practical case of inclined closed high-rise buildings is introduced;based on this case,the selection of overall structural system,local structural system,key nodes and other issues are discussed in detail from the perspective of system decision-making.Through detailed analysis,it is pointed out that the selection of structural system is not a simple structural problem in the process of design.In this series of sequential decision-making,factors such as building function,structural stress,construction period,building economy and disaster resistance should be taken into account,so that the selected structural type can meet the comprehensive requirements of all the factors to the greatest extent.At the same time,because of the particularity of its architectural form,the existing structural system can not be directly applied to it.Architects need to think and analyze from the essence and basic principles of architectural mechanics,so as to obtain strong support of structural technology.Thirdly,in the construction technology,the construction method,construction simulation analysis and construction monitoring of a inclined closed high-rise steel structure are introduced in detail.The construction method and construction method are analyzed and studied.The construction method of this kind of building is put forward,the construction sequence is determined,and the innovative method for the installation of its connecting corridor is put forward.The main evaluation index of the method.Some construction mechanics problems such as construction internal force,scheme selection,determination of construction pre-deformation value,demolition of temporary support,formation of corridor,temperature effect and installation of secondary components are analyzed,and solutions are put forward.The problems that may be encountered in the monitoring scheme are preliminarily discussed,and some reasonable suggestions are put forward for the construction monitoring system,the construction monitoring method,the improvement and processing of the construction monitoring data and the early warning system of the construction process.At the end of the paper,with the gradual return of architecture and structure to integration and the great progress of construction technology,architects should strengthen the understanding of the essence and basic principles of architectural mechanics,master more knowledge of structural technology and construction technology,so as to face the challenge of high-density environment,put forward feasible countermeasures,and provide a livable building environment for people.
