首發時間:2023-05-12
摘要:參數化建模技術因其在結構設計中卓越的可調整性和對復雜形體建筑良好的適應性,日益成為結構工程師設計的重要工具。本文利用Grasshopper參數化設計平臺,編制了肋環型、肋環斜桿型、葵花形三向網格型和扇形三向網格型的單層球網殼結構快速參數化建模程序,以及兩種型式的混合球網殼快速建模模塊,將參數化結構模型轉換成Midas Gen結構分析模型,實現了參數化建模與結構分析的無縫銜接,基于一個工程實例應用,驗證了該程序的可行性和實用性,為結構工程師開發類似程序提供參考。

Development and application of parametric modeling of single-layer spherical lattice shell based on Grasshopper
Abstract:Parametric modeling technology is increasingly becoming an important tool for structural engineers because of its excellent adjustability in structural design and good adaptability to complex form buildings. In this paper, Grasshopper parametric design platform is used to develop fast parametric modeling programs of ribbed type, ribbedtypewithdiagonalbars, sunflowershapethree-waygrid and fanshapethree-waygrid of single-layer spherical lattice shell structure, as well as two types of hybrid spherical lattice shell rapid modeling module. The parametric structure model is converted into Midas Gen structural analysis model. The seamless connection between parametric modeling and structural analysis is realized, and the feasibility and practicability of the program is verified based on an engineering example, which provides a reference for structural engineers to develop similar programs.
