摘要
以梁柱理论中考虑剪切变形影响的割线刚度为出发点 ,导出单元的切线刚度 ,并由此探求考虑剪切变形影响的稳定函数模型的计算方法。经算例表明 ,该计算方法精确、可靠、方便。
In this paper,the tangent stiffness of the element is derived,based on the secant stiffness from the beam column theory with shear effects considered.The numerical method is explored to deal with the calculating problems in numerical processing of the stability function.Through the example,the proposed formulas and methods are precise,reliable,and convent to apply.
