桁架结构计算机辅助分析系统的研究与开（本科毕业论文设计）
摘 要
随着我国建筑行业的高速发展，桁架结构广泛应用于铁塔、桥梁、屋架等现代建筑中，各种大型的、形态结构复杂的桁架结构相继出现，使得传统计算方法难以适应工程分析的需要，出现了计算精度差、效率低、难以分析计算等问题。而现有桁架结构分析软件由于行业针对性不强，工程建模、后处理功能不完善等因素，没有很好地应用到桁架结构的分析计算中来。论文从桁架结构特点出发，围绕桁架结构计算机辅助分析需求，对桁架结构计算机辅助分析系统及其关键实现技术进行研究，开发了桁架结构计算机辅助分析原型系统。
论文首先对现有桁架结构分析软件进行分析和研究，总结其不足并分析其发展趋势。通过研究桁架结构特点，明确系统需求，给出由接口层、事务处理层、支持层组成的三层系统体系结构，并规划了包含构件编辑、显示查询、构件属性、载荷编辑、内力分析与显示、节点验算、计算模型显示和后处理在内的八大系统功能模块。接着对有限元分析技术，参数化建模技术，软件系统开发技术和AutoCAD二次开发技术等系统实现关键技术进行研究。最后，借鉴课题组现有的有限元分析模块，成功开发了桁架结构计算机辅助分析原型系统。
关键词：桁架结构，有限元分析，参数化建模，AutoCAD二次开发
ABSTRACT
With the high speed development of construction industry, truss structure widely applies in modern constructions, such as iron towers, bridges and roofs, truss structures with large-scale, complex forms come forth one after another, which makes the traditional structure analysis methods cannot meet the needs of engineer application analysis any more, come with many problems such as poor calculation accuracy, inefficient calculation and difficult calculation. However, the existing truss structure analysis software, available for structure analysis do not fit the curtain truss structure analysis well, functions like engineering modeling, post-processing are imperfect, has not applied well in the analysis computation of truss structure . This paper analyzed the features of truss structures, regarding demands of computer aided analysis for truss structures. Based on the studies on the computer aided analysis system for truss structures and its core technologies, a computer aided analysis prototype system for truss structure is developed.
This paper first carried on the analysis and the research to the existing truss structure analysis software, summarized its insufficiency and analyzed its trend of development. Through the research the characteristic of truss structure, made clear the system requirements, gave the three-tier architecture, which was constituted by interface layer, transaction processing layer and supporting layer, and designed eight system function modules, which contained the component edition, the demonstration inquiry, the structure attribute, the load edition, the internal force analysis and the demonstration, the node checking calculation, the computation model demonstration and the post-processing. Then this paper carried on the research for the core technologies of system, such as finite element analysis technology, parametric modeling technology, software system systems development technology and AutoCAD re-development technology. Finally, combined with the topic-based group existing finite element analysis module, developed the computer aided analysis prototype system for truss structure successfully.
