［摘要］參數化設計為結構工程師創(chuàng)造了結構快速建模的有利條件，使結構工程師能專注于結構方案比選與優(yōu)化的工作，從而制定出合理且經濟的結構方案。利用Grasshopper參數化設計平臺，編制了用于空間網格結構快速建模的程序，詳細介紹該程序如何將建筑模型轉換成SAP2000結構分析模型。考慮到構建用于施加荷載的面單元需要較大的工作量，二次開發(fā)了基于方位角計算的蒙板程序，進一步提高程序的建模效率與普適性。通過一個工程實例應用，驗證了空間網格結構快速建模程序的有效性和實用性，為結構工程師開發(fā)類似程序提供參考，使復雜結構的建模分析效率得到提高。

Abstract:The parametric design creates the opportunity to the quick structural modeling for the structural engineers which makes the structural engineers are able to concentrate on the structural selection and optimization in order to obtain the reasonable and economic structure scheme. A quick structural modeling program for spatial latticed structure was developed on the Grasshopper parametric design platform. The process of converting the architectural model into the structural analysis model of SAP2000 was introduced comprehensively. Because a lot of work was needed to construct the face element for loading, the skinning program based on azimuth calculation was developed to improve the modeling efficiency and universality of the program. The effectiveness and practicality of the program for quick structural modeling of spatial latticed structure were verified through the engineering applications. This program can provide the reference for the structural engineer who develops similar functions. The efficiency of complex structure modeling and analysis can be improved greatly.
