刚架剪力、弯矩图浅析

Plain Analysis of Shearing Force and Bending Moment in Rigid Frame

根据弯曲内力图可以确定危险截面的位置,并能进行强度、刚度校核方面的工作,因此,全面掌握弯曲内力图是材料力学中的一个重点。而由于种种原因,目前对刚架中弯曲内力图的绘制存在较大的困难。就如何绘制刚架中的内力的剪力／弯矩图进行了详细分析。

According to bending internal force figure, we can make sure the position of critical section and check the intensity and rigidity. So it is an emphasis to roundly master the bending internal force figure. But there is much difficult to protract the bending internal force figure in rigid frame due to multitudinous reasons. This paper gives some detailed analysis of shearing force, bending moment of internal force in rigid frame.
