摘要:大跨空间结构节点往往呈现出复杂性和多样性，建模及分析过程要求较高。而现有土木工程软件基本都不具备专门针对空间结构复杂节点的设计分析功能，设计者进行节点分析，需要花费大量时间整理参数、建立模型。为此，借助Matlab-GUI强大的可视化功能，结合Ansys优越的分析功能，编制了人机交互参数输入—参数化建模—有限元分析—自动生成分析报告的智能化程序(Intellectualized Analysis System for Steel Joints)，此系统初步版本拥有15类复杂节点的分析功能，同时具备信息查询、结果输出等多项辅助功能，为空间结构复杂节点的设计、分析一体化提供了一条快捷和高效的途径。

Abstract: Large-span spatial structure nodes often presents the properties of complexity and diversity, resulting a high requirements in modeling process and analysis. The softwares mostly used in Civil Engineering fail to meet the function needs for specific space structure design and complex node analysis. It usually takes the designer large amount of time in the adjustment of the parameter and modeling during the node analysis. Therefore, applying the powerful visualization of Matlab-GUI and the superior analytic function of Ansys, Intellectualized Analysis System for Steel Joints embodies the features of human-computer interaction parameter input -parameterized modeling-finite element Analysis-automatic generation of intelligent Analysis program. The preliminary version of this system has the analysis function of 15 different node kinds, simultaneously with a number of auxiliary functions such as information search, results output. It provides a quick and efficient approach for the complex node design, analysis, integration of space structure.
