This article examines the results of a comprehensive study of crack formation processes in flexural and tensile reinforced concrete structures.
A method for calculating reinforced concrete beams is proposed, allowing for the determination of crack spacing, confirmed by experimental studies of finite element models and physical specimens. The results of this study are aimed at improving the reliability, durability, and design efficiency of modern reinforced concrete structures.

Keywords: reinforced concrete, crack formation processes; crack spacing, pre-stressed, numerical simulation, software package, bonding, calculation method, stretching, bending
