Abstract: According to the testing data about crack resistance performance of domestic concrete component, an optimum fitting of a curve of relations between influential factors of sectional height and sectional heights is made by using rational fractional interpolating function. And then a rational continuous curve, which shows that the influential factor is lowering with increasing of sectional height,is given.Moreover, the theoretical calculation values coincide better with measured values. The result may be used for reference in engineering design and code revision.
