Research On Application Of Parametric Desigh In Surface Of Landscape Bridge

With the rapid development of the economy,the construction of Beautiful China is also in full swing,the aesthetic needs of the people are increasing,and the aesthetic requirements for landscape bridges are also increasing.Landscape bridge designers continue to draw inspiration from architectural surface design theory,integrate fine arts and artistic elements,pay attention to the aesthetic experience of the masses,and show the taste of urban culture,gradually transforming from a single bridge to a complex of transportation,art,culture,and technology.In the design stage of landscape bridges,the existing modeling technology cannot adapt to the design trend of "surfacing".The parametric design method can convert the control elements of the "surfacing" landscape bridges into parameters,through certain logical rules.By generating each component of the model,the models of multiple landscape bridge schemes can be obtained more accurately and quickly.This study applies parametric design methods to the design of landscape bridge surfaces,and discusses the parametric generation methods of various types of bridge surfaces.The paper first introduces the Rhino+Grasshopper platform,and introduces the characteristics of each parametric design software platform.Through analysis,it is determined that the Rhino+Grasshopper parametric design platform is used to complete the parametric design of the landscape bridge surface in this paper.The paper studies the parametric form of bridge surfaces;by sorting out and analyzing the development process of building surfaces,it summarizes the objective trends and potential laws of building surfaces development,and uses design ideas and core algorithms as control factors to obtain the classification of parametric building surfaces.Two-dimensional distribution;explore to introduce the concept of surface from construction engineering to bridge engineering;through comparative analysis,compare the design focus of bridge surface and building surface,and carry out surface forms for different bridge types and surface design spaces through case analysis and other methods.Subdivision to explore the applicability of different bridge types and different component surface forms.The paper also studies the parametric generation of the surface of the space surface;according to the functions required in the surface generation process,it is written and organized into a plug-in for the parametric design of the landscape bridge surface at the plan stage,and combined with the plane surface parametric generation logic,the space surface surface parameter Research on the generation method,adjust and optimize the parameterized generation logic of the surface,and summarize the core logic of the generation of the surface on the space surface of various design ideas.Through the Rhino+Grasshopper software platform and the parametric auxiliary design plug-in for landscape bridge surfaces in the scheme stage,the parametric simulation of different types of bridge surfaces is performed.For bridge surfaces with different design ideas,according to the commonly used core algorithms,8 typical landscape bridge cases,including Shenzhen Qianhai Menghai Bridge,Shandong Weihai Shijiahe Park Bridge,and Nanjing Pukou Youth Olympic Park Bridge,were selected to simulate the generation of bridge surfaces.The parametric simulation results show that the method has certain practical value in the stage of landscape bridge planning.
