摘要
根据数值计算结果拟合出楔形构件高精度的转角-位移关系。根据单段楔形构件的4个约束刚度系数,对单段、两段、三段变截面构件组成的钢梁在刚架发生无侧移失稳时对钢柱的转动约束进行分析,给出了高精度的计算式。这些公式可以方便柱子稳定性的计算,也可方便软件的编制。
Based on numerical analysis, an explicit rotation-deflection relation of tapered members is presented. The rotational restraints of beams to columns are derived when the portal frame buckles in a non-sway mode. The beams may be composed of multiple segments of tapered members. These restraints are intended for an easier determination of the column effective length both in manual calculation and computer software.
