用弯剪法计算两向正交正放平板网架各杆内力

Calculating for Bar Internal Forces of Two Dimensional Normal Intersection and Putting Net Truss Structure by Means of Bending Moment & Shear Method

本文在节点法和截面法的基础上 ,将两者融为一体 ,为计算两向正交正放平板网架各杆内力 ,提供了一种新颖方法 ,称其为弯剪法。文中引用了实例 ,结果与其它方法完全一致 ,并符合实际 ,这就证实了本法的有效性和可靠性 ,有一定的参考价值。

In this paper,based on the method of joints and sections melted a body with them,a new method is proposed for calculating all bar internal forces of two dimensional normal intersection and putting net truss structure,which is called the method of bending moments and shears.An example shows that its result is coincided with other methods and corresponded to practise,the validity and reliability of this method are verified.It may be referered.
