摘要/Abstract

摘要： 结合结构力学的教学实践,给出了几何构造分析概念在求解静定结构内力、用机动法作梁的影响线、应用虚功原理求静定结构反力等方面的应用;分析了自由度、计算自由度、结构动力计算自由度、稳定性问题的自由度之间的区别与联系;汇总了力法、位移法等方法的特点及适用问题;介绍了部分结构力学内容应用多媒体、实验、数值仿真相结合的教学方法。将结构力学内容的内在联系、容易混淆的概念、各种方法的特点理清楚,从而提高教学效果。

关键词: 结构力学, 教学方法, 教学实践

Abstract: Based on the teaching practice of structural mechanics, the concepts of geometric structural analysis are used for determining the internal forces of statically determinate structures, with the kinematical method to construct the influence lines of beam structures, and with the principle of virtual work to calculate the reaction forces of supports of statically determinate structures; The differences and the relations among the degrees of freedom, the computational degrees of freedom, the structural dynamic computational degrees of freedom and the degrees of freedom for stability problems are analyzed; The characteristics and the applications of the force method, the displacement method are reviewed. The method of applying the multimedia, the experiment and the numerical simulation in teaching the structural mechanics is discussed. The intrinsic relationship in the structural mechanics, some confusing concepts and the characteristics of various methods, are clarified.

Key words: structural mechanics, teaching method, teaching practice
