建筑力学中应用叠加法绘制弯矩图的新探讨

The New Discussion on Using the Overlapping Method in Architectural Mechanics

力学是人类对自然现象的观察以及在生产劳动中的经验总结。建筑力学在由建筑构件组成的客观世界中发挥着最基本的认识作用。在建筑力学中,叠加法在绘制弯矩图中有着重要的作用。文章在教学实例的基础上阐述了建筑力学中叠加法的基本原理和推导过程,概括了易懂的基本操作步骤、适用条件和使用特点,列举了典型的计算例题,并使用Matlab软件给出了手算与机算的差别,为建筑力学实践教学提供有益的参考。

Mechanics is the observation of natural phenomena and the summary of experiences in the production and labor work.Architectural mechanics plays a fundamental role in the objective world composed of architectural components.In architectural mechanics,overlapping method plays an important role in drawing bending moment diagram.Based on the teaching examples,this paper expounds the basic principle and derivation process of overlapping method in architectural mechanics,summarizes the basic operation steps,applicable conditions and application characteristics that are easy to understand,enumerates typical calculation examples,and gives the difference between manual calculation and calculation by using MATLAB software.The new discussion of overlapping method in this paper can provide useful reference for the practical teaching of architectural mechanics.
