摘要
本文根据实际设计的需要,推导了部分预应力混凝土(简称PPC)双筋箱梁在使用荷载作用下截面开裂后钢筋及混凝土应力的计算公式,其表达式可以直接用于PPC双筋梁的应力计算。
According to the needs in actual design work, the formulas of stress computation for PPC double reinforced box girders after cracking under working load are derived. The formulas can be used for the stress computation of such beams directly.
