［摘要］参数化设计为结构工程师创造了结构快速建模的有利条件，使结构工程师能专注于结构方案比选与优化的工作，从而制定出合理且经济的结构方案。利用Grasshopper参数化设计平台，编制了用于空间网格结构快速建模的程序，详细介绍该程序如何将建筑模型转换成SAP2000结构分析模型。考虑到构建用于施加荷载的面单元需要较大的工作量，二次开发了基于方位角计算的蒙板程序，进一步提高程序的建模效率与普适性。通过一个工程实例应用，验证了空间网格结构快速建模程序的有效性和实用性，为结构工程师开发类似程序提供参考，使复杂结构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.
