Experimental and numerical research into cracking behavior in a reinforced concrete beam subjected to a restrained imposed curvature

Cracking of concrete is a frequent phenomenon during the lifetime of a structure. Making reliable predictions of crack widths is a difficult task that leads to much discussion in the professional practice, especially if there are cracks caused by restrained imposed deformations. An important parameter in crack width formulations is the effective concrete area in tension, which is often determined by a simplified approach. In this research, experimental and numerical research is conducted to increase insight into crack behavior where it is focused on the effective concrete area in tension.
