对我国规范GB50010—2002、美国规范ACI318-05和欧盟规范EN 1992-1-1:2004关于荷载作用下钢筋混凝土受弯构件的裂缝宽度控制标准、裂缝宽度计算原理和方法进行了比较分析。以试验数据为样本,对上述各规范的裂缝宽度计算公式进行了定量比较。并比较了各规范允许的裂缝宽度。结果表明,按我国规范GB50010—2002计算的裂缝宽度较大,该规范对裂缝的控制要求较严。在此基础上,并结合有关的试验资料,对钢筋混凝土构件的裂缝控制提出了建议。 The comparative analysis is made between China standard GB50010-2002, American standard ACI318-05 and European Union standard EN 1992-1-1: 2004 on the control standard of crack width and the calculation principle and method of crack width of reinforced concrete flexural members under load. Based on the experimental data, the formulas for calculating the crack width are compared quantitatively. The widths of cracks allowed by the codes were also compared. The results show that according to China’s standard GB50010-2002 calculated crack width larger, the specification of crack control requirements more stringent. On this basis, combined with the relevant test data, some suggestions are put forward for crack control of reinforced concrete members.
