摘要
建立了预应力钢 -混凝土组合梁考虑滑移效应和预应力筋内力增量的弹性抗弯承载力计算公式 ,提出了预应力钢 -混凝土组合梁考虑预应力筋内力增量的极限抗弯承载力的两步计算法。计算结果与试验结果吻合良好。建议的计算公式对预应力钢
A formula of calculating the elastic moment of prestressed composite beams is derived with account of slip and stress increase of steel tendons.A two-step method of calculating the ultimate moment is proposed with account of the stress increase of steel tendons.The predicting results show a good agreement with the measured elastic moment and ultimate moment.The proposed formula can be applied to the analysis and design of prestressed steel-concrete composite beams.
