Control Crack Width by Nominal Tensile Stress for RC Beams
In order to convenient application in optimum design of large and complex structures, theoretical formula of nominal tensile stress of concrete is deduced relating to the maximum crack width of RC beam in serviceability. By further statistical analysis of test data in certain reliability, simplified and practical formulas are proposed for calculating the nominal tensile stress of concrete. Therefore, the control of maximum crack width is replaced by control of nominal tensile stress of concrete, which shall be easier to realize in optimum design of concrete structures.
