摘要:
建立既满足纵向变形协调条件又满足梁截面M-N-Φ关系,且普遍适用的梁无粘结筋应力增量的计算方法,计算结果与已有的试验结果吻合良好.对超静定梁曲线型无粘结筋应力增量的计算表明,跨高比影响较小,其应力增量值与跨中集中荷载作用下直线型无粘结筋大致相等。
Abstract:
A generally applicable method is formed for calculating stress increment of unbonded tendon in a beam. The method satisfies both to the compatibility conditions of longitudinal de formation and the N-M-Φrelation of beam section. The results of calculation
