Parametric Generation Of Main Structure Of Stilted Building ——Taking Southwest Hubei As An Example

Southwest Hubei,also known as "western Hubei",is located in the southwest of Hubei Province and the north of Wuling Mountain.It has abundant rainfall during the same period.As the main construction form of traditional dwellings in Southwest Hubei,stilted building not only has distinct national cultural attributes,but also has typical ecological adaptability characteristics.This paper takes the stilted building in Southwest Hubei Province as the research object,takes its main structure form as the breakthrough point,carries out the research by means of literature reading,field research,craftsman interview and architectural surveying and mapping,extracts the mathematical characteristics of the main structure and component design of the stilted building from the research results,and quantitatively analyzes the dynamic data association law of the main structure design of the stilted building.Based on parametric and programming language tools,this paper summarizes a method to translate the design rules of the main structure of the stilted building into the rules of computer logic construction,so as to construct the main structure generation model of the stilted building.This paper makes a systematic and quantitative study on the main structure of stilted building in Southwest Hubei Province,adopts the structure generation model to retain its dynamic data association,and tries to record and continue the architectural form of local traditional dwellings,so as to promote the standardized and scientific design of dwellings in this area.This paper is divided into two parts according to the research order.The first part is the research on the design features and components of the main structure of the stilted building in Southwest Hubei.First of all,the design features of the main structure of the stilted building are extracted by integrating a large number of data from surveying and mapping,field investigation and interviews with craftsmen.This paper discusses the design features of the main structure from the main factors affecting its form,such as the selection of materials,the characteristics of the wooden frame,the characteristic structure,and the four types of typical stilted buildings.Secondly,it classifies and studies the smallest unit of the main structure building components,systematically summarizes the characteristics and functions of the structural components and functional components of the stilted building,and quantitatively analyzes the design rules such as the size data and the relative position relationship in space.The first part is the research basis of the second part.In the second part,taking the three most common forms of the stilted building,"one-sided house","key head" and "sanheshui" as examples,the main structure generation experiment of the stilted building is carried out.Through the analysis of the related cases of architectural generative design,the rule-based structural strategy is selected for the study of the main structure generation of the stilted building.The design rules of the main structure of the above three types of stilted building are extracted,and combined with programming language and parametric tools,they are translated into computer executable logic rules,such as the rules of component generation and the combination rules of the main structure.On this basis,the main structure generation models of three typical types of stilted building are established.This paper discusses the related factors affecting the main structure form,analyzes and summarizes the dynamic data association law of component design and main structure construction,and proposes a method to translate the relevant laws into the rules of computer logic construction.On the basis of these rules,three main structure generation models of three common shape stilts are constructed.
