Research On Optimal Design Of Complex Morphology Sports Architecture Based On Parametric Technology

Under the support of the philosophical theory of contemporary complexity science and the technology of digital design and construction,China's spo rts buildings are booming,and a large number of sports buildings have gradually emerged with a trend of complex form design,which is characterized by the complexity of “shape”—study design.The nonlinearity and the ease of construction coexist;the complexity of the "state"-the innovation of the form and the performance of the structural design coexist.As a result,the unique construction problems inherent in large-span sports buildings have become more complex and diverse.The contradiction between complex surface design and low-tech construction,the urgent requirements of the competition and the contradiction between the construction period and the expected completion of the modeling effect continue to intensify.Therefore,this paper attempts to use the parametric technology and related tools combined with relevant optimization experiment simulation to explore the optimization design method of complex form sports architecture,in order to improve the current situation that affects its construction rationality.The first chapter introduces the background of the research,clarifies the research object,the problem,the purpose and the meaning,and analyzes the research results at home and abroad,laying the foundation for the research.The second chapter analyzes the complexity of the "shape" and "state" of contemporary sports architecture through the case,analyzes the parametric technology related tools such as performance simulation and optimization algorithm,and constructs its relevance in different design stages of complex form sports buildings.The logical shape of the factors,the preliminary design of the multi-disciplinary fundraising collaborative calculation and the construction drawing design optimize the rationality of the construction.The third chapter is the main factors affecting the rationality of construction,such as the mismatch between complex form and construction technology,and the lack of efficient and economical customization techniques for a large number of non-standard components.It sums up the easy-to-build and mechanical properties of the "shape" of traditional curved surfaces and free-form surfaces.The efficiency of the "state" of spatial performance is based on the optimization design direction and principle.The optimization design process based on the "form" and "state" of parametric technology is discussed.In the fourth chapter,based on the design principle of "shape",the three strategies of standard unit assembly,discrete assembly of linear components and integrated information management are proposed.Under its guidance,standardization is improved by symmetrical mass layout,repeated assembly modules,and standard fa?ade panels;construction simplification is improved by flatness of free-form surfaces and optimization of non-twisted nodes and expandable surface fitting.Parametric technology enables multi-disciplinary collaborative work,comprehensive experimental simulation optimization and accurate construction of information BIM tools.The fifth chapter analyzes the characteristics of the three structural types of lattice system,thin shell system and tension system in sports architecture.Based on the principle of high efficiency of "state",the rational structure selection,with the help of parametric technology related tools and algorithms to accurately grasp the spatial structure A variety of performance indicators,through the structure of bionic mimicry,physical topology,physical and chemical flow lines to obtain efficient topological relations,through the parametric simulation of the inverse suspension experiment,optimization algorithm shape control,grid shell size optimization to achieve a rational "find shape."...
