摘要
在教学中,仅研究杆系在弹性范围内的应力和变形的计算,并采用许用应力法建立强度条件,但这对工程实际来说,还不全面.文中以普朗特简化曲线为理论依据,按极限载荷法对简单超静定杆系结构进行了强度计算,发现其过程比较容易,且也可同样进行强度问题的三种计算.
The stress and strain in the range of elasticity are just studied under teaching, and the permissible stress method is adopted to set up intensity condition, which is not all-sided to project reality. This paper takes the PLANT simplified curve as theoretical foundations and has a calculation of intensity on the simple superstatic bar series structure according to the load limit method. It is found that the above process is relatively easy and three kinds of calculation of intensity can be carried out too.
