Research On Generation Design Of Suburban Country Houses Based On Parametric Shape Grammar

The rural settlement is a social community produced by humans from multiple social relations within a certain geographical area.It is developed from long-term common production and life accumulation.It contains the collective memory of the villagers and the specific atmosphere of the village.It is the life that sustains the villagers.Common bond.However,with the large-scale increase in the demand for rural construction,the architects who have poured into the countryside rely on the mature experience of urban settlement planning and use "barracks",homogenization,low cost,etc.in a limited design cycle.Interpretation of "a new generation of large-scale rural housing.This mode of development inhibits the villagers’ expression of the sense of belonging and right to speak of the native village,weakens the vitality of self-organization and participation in the construction of rural settlements,and disintegrates the inherent context of traditional rural spaces.In recent years,in the context of the country actively promoting the construction of beautiful villages,creating a livable,green and environmentally friendly living environment has become an important part of the construction of beautiful villages.In this context,the design of large-scale rural houses oriented to user needs has become a research hotspot.Among them,based on the application research of the parametric shape grammar of rural spatial morphology research and computer graphics operations,the combination relationship between spatial morphologies can be translated into visual calculation by the initial state module(simple geometric elements)The strategy(reflection,deformation,integration,iteration and other rules)is converted into a deductive process of complex forms,and in this process,the conversion content,implementation sequence and iteration number of the calculation strategy can be manually intervened and adjusted according to the design needs.Therefore,this paper explores the establishment of a large-scale rural residential design method based on shape grammar from the three levels of theory,method and tool from the perspective of thinking to the process level.The research content includes the following three aspects:(1)Analysis of shape grammar and parametric shape grammar.This article starts with the intersection of computer and architectural design,and analyzes the basic definition and application method of shape grammar and parametric shape proposed by G Stiny.The shape grammar and the parameterized shape grammar are refined into the shape’s graphic model and parameterized model,and the definition of basic graphic elements(line,shape,length),the relationship between graphic elements and common grammar rules are combed.On this basis,taking the shape grammar of Palladio style villa as an example,the application process of grammar is analyzed.(2)Formulation of large-scale rural housing design rules related to suburban rural morphological characteristicsAfter clarifying the basic concepts of the parametric shape grammar,we analyzed the morphological characteristics of the research object-suburban rural residential buildings.Because this article takes architectural design as the main research content,the research on morphology mainly focuses on the homestead level,residential single level and residential detail material level.Through field research and literature research on typical villages in North China and China’s rural housing laws and regulations,the key features and specific data of rural housing design are sorted out,and the original spatial organization method is integrated with the modern residential architectural design experience.Establish a complete set of shape grammar rules for rural houses.(3)Large-scale rural residential design and application.Based on the design rules of the existing rural residential shape grammar,by defining the application process and application objects of the grammar,a graphical model of the grammar is first established,and data extraction and function translation of the rules based on the graphical model are further established to further establish a grammatical parametric model.With the help of Grasshopper software during the model building process,the multi-generation results of the grammar can be intuitively presented as a three-dimensional model for occupants and architects to judge and modify.Taking Renli Village in Jinan as the simulation environment,5 families were selected as the simulation objects for the design,and the rural houses and their drawings and feedback data based on their specific needs were generated.The logic of the residential generation design based on the parametric shape grammar is clearer and more organized,and increases the possibility of residential extension and extension,so that users can self-organize construction according to the rules.Explore the possibility of interaction between architects and users in the computer system for parametric design of largescale rural houses,try to restore the "harmony and different" style in the context of new rural construction in China,and achieve complexity at the level of rural residential building design Rich and delicate space texture.
