Practical Calculation Approach of the Width of the Maximum Crack in the Reinforced Concrete Rectangular Section Beam

This paper derives the tabulation formula and calculation sheet of the width of the maximum crack of the rectangular section beam from the formula in the Code.The width of the maximum crack can be directly found out by the table check method.Compared with the calculated result by the formula in the Code,the table check method can completely meet the requirements of the design precision.
