The factors involved in controlling main cracks are the reinforcement stress, the bond characteristics of reinforcement, the distribution of reinforcement, the diameter of the steel bars used, the steel percentage, […]
EK276
The behavior of main cracks changes at two different stages. At low tensile stresses in steel bars, the number of cracks increases, whereas the widths of cracks remain small; as […]
EK275
Main cracks develop at a later stage than secondary cracks. They are caused by difference in strains in steel and concrete at the section considered.
EK269
In general, concrete cracks may be divided into two main types: secondary cracks and main cracks.
