摘要
根据薄壁杆约束扭转理论 ,对任意多边形薄壁杆断面几何参数分析建立了一套便于计算机实现的计算方法和相关公式 ,并编制了相关程序。算例分析表明该方法计算结果正确 ,可在工程设计中应用。
Based on the theory of restraint torsion,a method for computing the sectional geometric properties of thin-walled elements with arbitrary polygon sections,which is convenient for developing the relative programs,is presented. The comparison of calculated results with the results of the references shows good agreement.
