在进行轴心受压构件设计时,截面面积一般都通过规范公式进行迭代求解获得。但是迭代法因需反复计算而显繁琐。为解决这一问题,本文通过引入表示构件截面特性参数.使之与构件长细比关联,并与现行规范验算公式联解而直接计算构件的合理长细比。这种方法克服了反复迭代的麻烦,在进行轴心受压构件截面设计时无须假设长细比反复试算,可根据设计已知量直接计算截面尺寸。文中提出方法的理论意义在于,它将轴心受压构件稳定性设计问题由传统的验算过程转变为直接求解过程,对于构件设计具有实用意义。
In the axial compression member design, the cross-sectional area is generally obtained through the iterative formula to solve the formula. However, the iterative method is cumbersome due to repeated calculations. In order to solve this problem, this article directly calculates the reasonable slenderness ratio of components by introducing the parameters that express the cross-section characteristics of the components, correlating them with the slenderness ratio of the components, and coupling with the existing standard checking formula. This method overcomes the problem of repeated iterations. When designing the cross-section of the axial compression member, it is not necessary to assume that the slenderness ratio is repeated trial calculation, and the cross-sectional dimension can be directly calculated according to the known amount of design. The theoretical significance of the proposed method in this paper is that it transforms the stability design of the axial compression member from the traditional checking process to the direct solving process, which is of practical significance for the design of components.
