本文分析了折线配筋砼等高梁的抗弯强度问题,分別对矩形截面梁及Ⅰ形截面梁推导出计算折线筋面积的公式,可适用于承受分布荷载或移动集中荷载作用的等高梁,预应力砼梁及普通钢筋砼梁均可利用这些公式进行纵筋计算。文末附有数字计算例题。
This paper analyzes the flexural strength problems of sorghum and other sorghum beams, and derives the formula for calculating the ridge area for rectangular section beams and I-shaped section beams respectively. The formula can be applied to the contour beams subjected to distributed loads or moving concentrated loads. Both stress trusses and ordinary reinforced concrete beams can use these formulas for longitudinal reinforcement calculations. At the end of the text, examples of numerical calculations were attached.
