摘要
对连续梁和双杆框架模型的初始后屈曲进行了研究。通过有限自由度和无限自由度简支梁变形能相等的方法,求出有限自由度简支梁的弹簧刚度系数k,并用研究有限自由度双杆框架代替无限自由度双杆框架模型来求载荷与变形的关系,并做出其关系曲线。
The early buckling of models of continuous beams and the frames with two bars were studied.The spring rigidity coeficient k of the finite degree of freedom of the simple branch beam was obtained through the deformation energy phase method of finite degree of freedom of the simple branch beam.The relation between loads and deformation was obtained by using the frames with two bars of finite degree of freedom to replace the model of the frames with two bars of infinite degree of freedom and then the relation curves were drawn.
