摘要
指出钢筋混凝土新老混凝土收缩差的影响,加大了结构的挠度,降低了结构的抗裂度。针对这一问题,对新老混凝土收缩差的影响进行了分析研究,提出了在结构分析时钢筋混凝土收缩力、收缩应力和挠度的计算方法。
It pointed out that new and old reinforced concrete shrinkage influence oversized structure deflection and decreased structure anticrack. Aiming at the problem, the new and old concrete shrinkage difference influence was Studied analytically, and the Calculation methods of reinforced concrete shrinkage, shrinkage stress and deflection in structural analysis were proposed.
