| The traditional houses in our country are a very precious and unique historical heritage,which has important social and economic value in today’s society.With the continuous development and progress of society,while promoting the vigorous development of modern architecture,we should also promote the sustainable development of traditional architecture in order to ensure the inheritance and development of traditional culture.Nowadays,many traditional folk houses are facing different degrees of destruction.How to properly protect and plan them has become an urgent problem to be solved in contemporary times.On the basis of the field investigation in Pingjiang area,this paper collects the structural data of well-preserved traditional folk houses,and makes a detailed study and summary of characteristics of frame structure.Finite element analysis is also used for theoretical analysis and experimental simulation.The specific research content is divided into the following five parts:The first chapter mainly introduces the research background of traditional folk houses in Pingjiang.This paper discusses the significance of research and the current research situation at home and abroad from the importance of structural analysis.It also explains the research method and structure of this paper.The second chapter introduces the types and general situation of the frame structure of traditional folk houses in Pingjiang.The frame structure is mainly divided into gable shelving purlin type,lifting beam type and gable purlin type side paste combination,lifting beam type side paste combination and bucket type side paste combination.Among them,according to the support system,it can be divided into the joint technology of column and beam,the joint technology of column and purlin,and the joint technology of house.According to the beam form,it can be divided into round straight beam,flat straight beam and flat moon beam.The third chapter first introduces the extensive application of finite element analysis software.Taking the main frame structure of Pingjiang area as the research object,the data of the structure is obtained by field surveying and mapping,and the finite element method is used to establish three-dimensional model and static analysis.The stability and rationality of frame structure are discussed from the point of view of mechanics.The fourth chapter summarizes the main components of traditional folk houses in Pingjiang area,and elaborates on the structural characteristics of the inner forehead beams,shovels,piers,buckets and spider buckets.The finite element analysis software is used to establish the three-dimensional model of different components.The preliminary finite element static analysis is done to discuss the scientific and stability of the structural characteristics.The fifth chapter summarizes the content of the research,and puts forward the prospect of the shortcomings in the research.Through the analysis of the frame structure and special building components of traditional folk houses in Pingjiang,the finite element software is used to study the deformation under static action.Thus try to analyze the reasons behind the deformation and provide a theoretical basis for the protection and planning of traditional folk houses. |
