Abstract

Abstract

After the influencing factors on crack width in reinforced concrete members are analyzed, the formulas to calculate the limited stress of reinforcement to control the crack width are derived, and the succinct formulas of computing allowable stress of reinforcement are put forward by considering the maximum crack width and typical values of influencing factors, also the charts can be made. The control of crack width will be achieved if the stress is less than the allowable value, thus avoid calculating the crack width under service load. An example is used to compare and analysis theoretical results obtained from various codes.
- reinforced concrete flexural members,
- crack width,
- limited stress in reinforcement,
- influencing factors
