Reinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility.
The reinforcement is directed in the x, y and z direction. The reinforcement ratio is defined in a cross-section of a reinforcing bar as the reinforcement area A r {\displaystyle A_{r}} over the total area A {\displaystyle A} , which is the brittle material area plus the reinforcement area.

This is due to the fact that FRCM is placed on a substrate. In fact, it is necessary to take into account multiple failure mechanisms that can occur as a result of the interaction between support and reinforcement. Such mechanisms include: [16] the detachment with cohesive failure of the support from the reinforcement system;

Correct misinterpretations of free images. One of the main complaints about free images is lack of quality when compared with a promotional images. That is not true: there are very good free images as shown by Wikipedia:Featured pictures. In the case of replaceable images, it is possible that a promotional image will look better than free versions.
Wikipedia:Picture of the day is an image which is automatically updated each day with an image from the list of featured pictures. The {{ POTD }} template produces the image shown above. Category:Wikipedia Picture of the day lists the different templates that can be used.
