The Research On The Design Method Of Long-span Building Modeling From The Perspective Of Structure Type

With the continuous development and progress of the times,architectural design and its structure-related theories are constantly being updated and improved.In order to meet the diversification of people’s needs,building structures continue to optimize and innovate based on the basic force principle,resulting in different structural types and forms.feature.Among them,the various types of large-span structural forms have brought creative soil and opportunities for architectural modeling design,and how to design excellent architectural modeling is still a problem for most architects.This paper selects the large-span building structure as the research object,sorts out the development process of the large-span structure,and clarifies the unity of the structural form and the architectural model in the creation.By analyzing the internal structural logic rules of long-span building structures,using inductive and deductive methods to classify large-span building structures,and researching the evolution of structural morphology according to different types of large-span structures.At the same time,using the theory of architectural intention and geometry,the solid geometric prototype and its changes are derived from the plane geometric prototype and its changes,and the changes of the architectural geometric prototypes in the architectural modeling design,such as circles,squares,spheres,cylinders,cubes,etc..Then match the change strategy of the long-span building structure form and the geometric forms expressed under its structural logic,such as arch,droop,arc,concave and convex,etc.,to jointly derive a wide variety of large-span structural forms and different architectural geometries under the architectural intention The corresponding relationship between the shapes provides logical support for the design of large-span buildings.This paper also combines many excellent large-scale public building cases at home and abroad with a close combination of large-span structures and architectural shapes,and conducts a targeted graphical analysis of large-span building structures,and sorts out and summarizes the changes in large-span building structural components and units.According to the ideas of the same structural component change,different structural unit combination and structure type arrangement of the large-span structure,this paper attempts to propose component parameter control,component adjustment and optimization,component topology cutting,unit type superposition,and unit juxtaposition arrangement.The span architectural modeling design method hopes to provide direction and ideas for designers and design students to design large-span architectural modeling in the future.
