Research On Optimization Design Of Modern Light-frame Wooden Housing Based On BIM Technology

In recent years,wood has been widely used in architecture as a natural renewable material.As a relatively mature building type,light-frame wooden housing has been widely practiced in North America and Europe,and a highly mature building system has been formed.However,the development of light-frame wooden housing in China is still in its primary stage.At the same time,China’s construction industry is in the era of construction industrialization 4.0.In this era,light-frame housing also needs to transform to an information-based,intelligent design and construction mode.Therefore,in view of the above background,this paper aims at the problem that a large amount of raw materials are wasted due to insufficient design preparation in the construction of light wood structure residences,resulting in high construction costs that make it difficult for this type of residence to be promoted in China.The intelligent planning of the layout achieves the purpose of maximizing the use of materials and saving costs.The optimization steps are as follows: First,based on the development status of China’s light-wood structure houses,combined with relevant domestic and foreign theoretical and practical achievements,it is concluded that the current lightwood structure houses in China should vigorously develop prefabricated production and prefabricated construction,with a view to saving construction resources,The purpose of reducing housing costs and improving construction efficiency.Secondly,taking this as the optimization goal,the design and optimization of the light-wood structure house has been studied from two aspects: First,referring to the international mature construction system,the foundation,wall,floor,roof,etc.of the light-wood structure house in China The traditional construction methods of the four categories make corresponding node optimizations,and the seismic performance simulation is conducted through finite element software to verify the rationality of the optimization methods.The second is based on the above residential construction system,with BIM as the technical support,through the preparation of the Revit-Dyanmo program to complete the parameterized modulus system and the matching parameterized prefabricated parts design,classify and code the parts to form BIM-based balsa Structural housing parts information database.And call the prefabricated parts in the database,according to the established design rules linkage in Revit,complete the architecture of the overall model of the house.Finally,taking the light wood structure residential project that the author personally participated in as an optimization object,the above method was applied in computer simulation.By comparing the benefits of the original and optimization models,the optimization method was superior to the original in construction cost,resources,and time The scheme further verified the feasibility of the optimization method.The optimization method of light-frame wooden housing introduces the Revit-Dyanmo parametric design tool,which takes full advantage of the information management of the BIM platform,and provides reference value for the prefabrication of light-frame housing in China.Moreover,it has reference significance for the application of BIM in prefabricated buildings.
