| With the economic development and the improvement of social living standards,people pay more attention to the presence experience gained in the commercial space during the consumption process.Also,the trendy and fashionable architectural design can greatly improve the quality of the building environment,attract customers’ attention,and achieve a good role of commercial drainage as well.At the same time,commercial competition will bring competition in architectural form and space.Only by seizing the opportunity of the experience model and creating an eye-catching and intriguing image to achieve differentiated development can we survive in the new era and seek better development.Therefore,the introduction of fractal theory,a frontier subject that focuses on morphological development,provides a new morphological design method for commercial architectural design,enhances the visual impact while enhancing the commercial atmosphere,expressing fashion culture in material form,and creating what is needed for experience economy building environment.Not only can the principles of fractal architectural design provide new attempts for commercial building design,and bring positive significance to the development of contemporary commercial building form language and cultural theme promotion,but also based on fractal theory to study commercial building form design,it can expand the principles and methods of fractal architectural design and improve methodological system of fractal architectural design principles.Based on the principles of fractal architectural design,this paper uses fractal iteration,graphic analysis,model analysis and other research methods to discuss the development trend of architectural form,the suitability of fractal theory in commercial building form design,and the design principles of fractal commercial building form.The method mainly includes similarity and isomorphism,mosaic rhythm,cultural fractal,combined with the fractal characteristics of commercial building facade morphology,and discussed the generation mechanism and design steps of the the Iterative Function System,Lindenmayer Branch System,Particle System and other software rule systems of the fractal commercial building space morphology generation design,and the possibility of its application in different commercial building space morphologies.Established the design method of structural form-finding and natural mimicry under the principle of similar and isomorphic design,the design method of repeated juxtaposition and mosaic superposition under the principle of mosaic rhythm design,and the design method of hierarchical juxtaposition and hierarchical recursion under the principle of cultural fractal design.Five types of fractal building facade morphology are formed: abstract simulation composition,concrete simulation composition,geometric weaving composition,topological deformation composition,and fractal iteration composition.Different generation mechanisms of Iterative Function System affine transformation based on computer software rules,intuitive fractal of Lindenmayer Branch System,mechanics simulation of Particle System,and corresponding design steps and generation methods are constructed.To a certain extent,it provides new ideas for the study of commercial building form systems,summarizes design methods under different design principles for forming symbolized commercial building facade forms,and provides software rule systems for generating experiential commercial building spatial forms parametric design tool.Fractal theory can provide new thinking for commercial building design,and create a commercial environment that fits the consumer society with new morphological design techniques. |
