摘要
论述轻型变截面门式刚架钢柱稳定计算公式的特点及楔形柱在刚架平面内、平面外的计算长度系数和等效弯矩系数的确定方法,方法也可用于横梁为变截面的刚架.
Features of column stability calculation in light portal frames are discussed. Methods for determining in-plane and out-of -plane effective length coefficients as well as equivalent moment factors are presented for tapered columns. Use of tapered rafters is also considered.
