【摘要】 利用轴心受压构件曲线的最小二乘法拟合公式，根据轴心受压构件的整体稳定条件，导出轴心受压焊接组合工字形钢构件长细比λ的简化计算公式；进而总结出一种轴心受压钢构件的简化设计方法。利用该方法可直接计算适用长细比λ，确定截面尺寸，可一次性完成，步骤简洁，适用性强，具有一定的实用性，可供广大设计人员参考。更多还原

【Abstract】 In this paper, according to the intergral steadness of axial prescure’s component, a simplified equation of A was build by the least square fit equation of line. And then, author make out a sincplified methord of steel member. By this way, a axial pressing component could be design directly from a suitble A. This is pithy and applicable methord.更多还原
