Abstract:The cracking problem in concrete structures is becoming more critical because of the upgrading of the allowable stresses, strengths, and deflections, and using ultimate load procedures in design. Reasonable information exists on methods of crack control in reinforced concrete beams. This paper deals with the present state of knowledge on cracking in concrete, procedures for crack control in exposed and protected structures, and improving flexural cracking behavior in beams, one-way slabs, and two-way slabs. Current acceptable expressions for determining crack width are applied to practical engineering designs. Also a discussion and tabulation of the permissible crack width in structures under different uses and exposures are pre-sented.
