Abstract: According to experimental data the author uses the simple calculation model to establish the calculation formulas of maximum crack width of reinforced concrete members subjected to bending, tension and eccentric compression. The formulas involve the main factors (steel bar stress, steel bar diameter, reinforcement ratio, steel bar arrangement, cracking strength of section, property of load, thickness of concrete cover, property of concrete, etc.). The results of calculation are in good agreement with the experimental data.

摘要： 本文根据试验资料,采用简单的计算模式,建立受弯、受拉和大偏心受压构件的最大裂缝开展宽度计算公式。公式考虑了影响裂缝开展的主要因素(钢筋应力和直径,配筋率,配筋方式,截面抗裂性,荷载性质,保护层厚度,混凝土性质等)。与试验结果相比,公式的符合性是较好或不差的。
