本文评述了以往钢筋混凝土构件抗裂度及裂缝宽度的计算方法。 根据大连工学院所作的试验，建议了钢筋混凝土构件抗裂度的计算公式。公式中的参数γ与截面形状、高度及荷载特征有关，其值如下：式中了γ０取自文献［１４］。 根据试验资料的统计分析，建议了受弯、轴心受拉、偏心拉、压钢筋混凝土构件最大裂缝宽度的计算公式：用试验资料对建议的公式作了验证，符合良好。
This article reviews the calculation methods for the crack resistance and crack width of conventional reinforced concrete structures. According to the test made by Dalian Institute of Technology, the formula for calculating the crack resistance of reinforced concrete members is proposed. The parameters γ in the formula are related to the cross-sectional shape, height, and load characteristics, and their values are as follows: where γ0 is taken from the literature [14]. According to the statistical analysis of the test data, the formula for calculating the maximum crack width of the flexural, axial-axial, eccentrically-pull, and compression-reinforced concrete members is suggested: The proposed formula is validated with the test data and is in good agreement.
