Simplied Calculation Method for Reinforcement of Rectangular Sectional Flexural Members Considering Crack Width

Abstract:

Article Preview

Based on maximum crack width checking of flexural member with rectangular section, the limited maximum crack width value of code was substituted into checking formula. In this paper, according to the different value scope of non-uniformly distributed strain of coefficient longitudinal tensile reinforcement, controlling equations expressed with the diameter and numbers of steel bars are derived, thus reinforcement meeting the requirement of crack width can be calculated directly according to known value. The example indicates that this method can avoid the repeated reinforcement adjustment and crack checking calculation process, and the reinforcement parameter can meet the requirements well. It may be a reference for the designers.
