摘要
本文提出一个计算 Bessel函数 Jp(x)及 Np(x)的近似方法并在 -∞ <p <∞和 x >0的范围内验证了方法的适用性 ,进而提出了截面按幂函数变化的变截面梁柱的刚度方程并研究了其临界力。
An approximate method for computation of the Bessel function J p(x) and N p(x) is presented at first and connecting with the application of the researched problems the validity of the method within the range from -∞<p<+∞ and x>0 is examined. The stiffness equations of beam-columns with varying cross section according to power function are then suggested and the calculated results are discussed. The determination of critical forces of these members is also studied and the results checked by the known results. The contributions of the paper can be regarded as a preliminary work for the research of the Elastic-plastic beam-column too.
