[摘要] 在當(dāng)今的BIM與參數(shù)化設(shè)計(jì)潮流中，結(jié)構(gòu)工程師在復(fù)雜建筑的建模方面需要有效的輔助建模工具。犀牛軟件與Grasshopper插件提供了快速有效的參數(shù)化設(shè)計(jì)功能。利用該軟件與插件編制了一個(gè)雙層網(wǎng)殼結(jié)構(gòu)快速建模工具，可以自動(dòng)劃分網(wǎng)殼上表面的網(wǎng)格，根據(jù)用戶(hù)輸入的網(wǎng)殼高度計(jì)算出下弦節(jié)點(diǎn)位置，并自動(dòng)創(chuàng)建所有桿件。本程序作為參數(shù)化設(shè)計(jì)的一個(gè)案例，能夠?yàn)榻Y(jié)構(gòu)工程師開(kāi)發(fā)類(lèi)似功能提供借鑒。

Abstract: In the trends for BIM and parametric design, structural engineers need efficient aiding tools for modeling of complicated buildings. Rhinoceros software and Grasshopper plug-in provide quick parametric design function. A quick structural modeling tool of double-layer reticulated shells was programmed which could automatically mesh the upper surface of the shell, calculate location of lower chord joints and create all members of the shell.  The program provides a typical case of parametric design and give guide to structural engineers who need develop similar functions.
