| 摘 要： | 本文推证了压杆稳定的动力准则,并推广到梁板等结构.得到轴向受压构件横向自由振动一阶固有频率的平方与轴向压力成线性关系,而构件稳定临界力对应于固有频率为零的特例.从而,可根据轴向受压构件一阶固有频率值推算出其稳定临界力,这种测试稳定临界力的方法称振动法.

| Abstract: | In this paper, the dynamic criterion for compression columns proved and was extended to beam and plate structures. The square of the first-order natural frequency for transversal free vibration of longitudinal compression components corresponds to the zero natural frequency, thus obtaining the critical load through the value of the first-order natural frequency of longitudinal compression components. This method for determinating the critical load is called the vibrating method. |
