为解决当前在钢结构建筑信息模型(building information modeling,BIM)与结构分析模型之间进行数据转换时存在的关键技术问题,本文在分析工业基础类(industry foundation classes,IFC)标准表达方法的基础上,以ABAQUS为结构分析平台,开发了钢结构BIM模型数据转换算法,运用C#语言和Xbim工具包,实现了结构构件信息提取、构件空间位置调整和分析数据自动添加,并形成了相应的转换软件;通过钢框架结构实例分析验证了该软件的可靠性和准确性,并将其应用于安阳市游客集散中心的BIM模型转换和结构分析。结果表明,所开发的算法和软件解决了生成的结构分析模型节点不连接和人工添加分析数据工作量大等问题,实现了BIM中的钢结构设计模型或深化设计模型向ABAQUS结构分析模型数据的准确转换。与传统的在ABAQUS中直接建立结构分析模型相比,本文提出的方法能大大提高复杂钢结构的结构分析建模速度和效率。
柯西中值定理涉及两个函数及其导函数之间的关系,其应用是高等数学的一个难点。通过对柯西中值定理结构的分析,得出其可以作用对象的结构特征,解决“为何用”和“如何用”柯西中值定理的问题,有利于帮助学生理解和掌握柯西中值定理的应用。Due to the fact that Cauchy Mean Value involves the relationship between two functions and their derivatives, its application is a difficult point in advanced mathematics. By analyzing the structure of Cauchy Mean Value, the structural characteristics of the objects it can affect are obtained, solving the problems of “why to use” and “how to use” Cauchy Mean Value, which is conducive to helping students understand and master the application of Cauchy Mean Value.
