本文给出了跨中有侧向和扭转支撑时单轴对称等截面简支梁在纯弯情况下屈曲问题的闭合解,得到了支撑临界刚度的计算公式,给出了临界弯矩和支撑刚度间的简单关系式。
In this paper, the closed solution of the buckling problem for a simple-symmetrical beam with uniaxial symmetry under lateral and torsional support is given. The formula for the critical stiffness of the support is given and the critical bending moment and the support stiffness are given. Simple relationship.
