Research On Computational Generative Design Of Post-disaster Transitional Housing

Since the beginning of the 20th century,China has continued to suffer devastating natural disasters such as floods,tsunamis,tornadoes,mudslides and earthquakes.In the plan to deal with major natural disasters,the design of post-disaster transitional housing buildings is one of the important measures to rebuild order after disasters,stabilize people’s hearts,and build confidence in reconstruction.Temporary transitional housing in emergency rescue is the most important place for people in the disaster area to live in a certain period after the disaster,which is of great significance to the research of post-disaster transitional housing.How to better improve the design of post-disaster transitional housing,develop the best evacuation route to prevent secondary disasters,and increase the post-disaster resettlement rate are important considerations.Based on this background,this paper takes post-disaster transitional housing as the research object,takes the post-disaster modular residential building integration as the theme,selects computer-generated design methods,discusses the planning and design methods for providing a set of rapid and scientific modular transitional housing for the post-disaster people from a fast and effective perspective,integrates the modular residential buildings of the postdisaster people with the algorithm generation algorithm of reasonable evacuation demand,and puts forward a new idea and research direction for the construction of post-disaster residential buildings.The research is divided into five aspects: the first is the introduction,which mainly introduces the research background of this paper,determines the research objectives and significance of this paper,and introduces the research objects,literature review and research methods involved in this paper.The second is the definition and main characteristics of postdisaster transitional housing,the analysis of the necessity of construction,the analysis of the current design status and the main existing problems,and the proposal of design countermeasures;The third is the application overview of modular buildings,including the principle and specification system of modular buildings,the advantages of modular houses in post-disaster reconstruction,the typical cases of modular buildings and the practical application after disasters,and the post-disaster application of existing residential modular buildings is analyzed and refined.The fourth is the research of computational generative design methods,sorting out the theoretical basis of algorithms,describing and establishing the composition rules of generative methods,and combining the feasibility analysis of computational design in the post-disaster site that meets the actual local conditions,by designing ant colony algorithm and cellular automata algorithm system to achieve the optimal evacuation path,establish the diversity and adaptability of public space nodes and group combination forms.The fifth is to adopt digital information operation to simulate the scheme and verify the feasibility,optimize the morphological diversity and spatial combination of the building from a quantitative point of view,substitute it into an actual site for verification,and complete a numerical calculation based on the calculation to provide a calculation generation tool for post-disaster transitional housing planning.This research provides reference and reference for the modular calculation and generative design of residential buildings,which is of positive significance for improving the quality of buildings and the efficiency of system operation.This study optimizes the streamlined organization design of post-disaster resettlement and expands the possibility of residential module combination through translation between traditional architectural problems and computer programming languages,aiming to link digital technology with the reality of post-disaster reconstruction work,and greatly improve the design level and work efficiency of post-disaster transitional housing construction.
