Abstract
Crack width evaluation of flexural RC member is evaluated analytically by two significant formulas given by researchers and four standard code i.e. IS 456-2000, BSEN 1992-1-1-2004, ECP 203-2007, ACI 318-95 and compared. Parameters such as clear cover, the effect of diameter, variation of depth, number of bars with the same cross-section and increasing external moment are considered for computing the crack width. From the study of results of this study, it can be concluded that clear covers estimated based on IS 456 2000 are highest and those estimated based on EGYPTIAN CODE; 203-2007 are lowest as compared to other codes and mathematical models considered in this study. It can also be concluded that crack width increases with increase in clear cover or external moment while it decreases with increase in reinforcement diameter, depth of the beam or number of bars.
