【摘要】 分析了蒙皮组合体墙板对轻钢钢柱侧向稳定的影响,探讨了该墙板体系的三种等效弹性支撑刚度,运用势能驻值原理推导了考虑蒙皮组合体墙板作用的钢柱平面外计算长度系数,给出了考虑该作用的柱顶临界轴力计算方法及对蒙皮组合体墙板的相应截面、规格要求,通过计算结果的分析,讨论了该法作为蒙皮组合体墙板设计方法的合理可行性问题,为工厂设计提供参考。更多还原

【Abstract】 Based on lateral stressed skin diaphragm restraint,the effect between steel column and stressed skin diaphragm is analyzed,three equivalent stiffnesses of stressed skin diaphragm is discussed,using principle of stationary potential energy,the length coefficient in outer plane of steel column is derived,and the formula of critical axial force of column and requirements for the lateral stressed skin diaphragm are got.Finally,with practical example the rationality of the method is discussed.更多还原
