On the feasibility of several main equations given in some Codes and references on the calculation of crack width of concrete flexural members, discussions are done with experimental data of about 140 specimens. It is revealed that the average crack width in every cracking stages can be expressed accurately by the product of average crack spacing in steady state (l_<av>) and average change in strain in reinforcing steel from the decompression (⊿ε_<sav>). On the calculation of l_<av>, Equation (6) is proposed herein which is modified from the equation provided in CEBFIP Code 1978 so as to be more simple and acculate. Good result of examination of this proposed equation with experimental data is shown in Fig.10 and can be compared with the result of CEB-FIP equation shown in Fig.8. Proposed equations on the average change in strain ⊿ε_<sav> are Eqs. (10) and (11). Succesful results of those values to experimental data are shown in Fig.11.
