摘要:参数化建模技术因其在结构设计中卓越的可调整性和对复杂形体建筑良好的适应性,日益成为结构工程师设计的重要工具。本文利用Grasshopper参数化设计平台,编制了肋环型、肋环斜杆型、葵花形三向网格型和扇形三向网格型的单层球网壳结构快速参数化建模程序,以及两种型式的混合球网壳快速建模模块,将参数化结构模型转换成Midas Gen结构分析模型,实现了参数化建模与结构分析的无缝衔接,基于一个工程实例应用,验证了该程序的可行性和实用性,为结构工程师开发类似程序提供参考。

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.
