摘　　要：基于梁的弯曲理论与结构概念设计的关系,采用静力等效的方法分析了弯矩和剪力的作用效应;同时,结合梁、平面桁架和网架等典型的工程结构,阐述了概念设计的过程和能够解决的问题。实践表明,该方法可以根据构件的弯矩图和剪力图提出其正确的概念设计方案,能够提高学生运用梁的弯曲理论对构件或结构进行概念设计的能力,能够促进对钢筋混凝土设计原理和钢结构设计原理的学习;是对材料力学传统教学方法的改革和补充。Based on the theory of mechanics of material,the method about using the mechanical theory in the concept design of elements or structure was introduced.Firstly,the role of the nature of moment and shear force was analyzed,secondly the concept design process and attention to the problem through the typical engineering beams,truss and other structural grid were systematically exposed.Concept design is the important part of improving the ability of solving practical problems with theoretical knowledge,which can promote the learning of reinforced concrete design principles and steel structure design principles,and is the reformation and supplement for the traditional teaching method of material mechanics.
