3. A concrete floor slab is reinforced by steel rods placed 38mm above the lower face of the slab and spaced 150mm on centers. The modulus of elasticity is 20GPa for the concrete and 200GPa for the steel. We know that a 100Nm bending moment of is applied to each 300mm width of the slab, calculate a) the maximum stress in the concrete, b) the stress in the steel. 138mm 100mm 150mm 150mm 150mm 150mm

Crack Detection

Concrete materials are meant for supporting structures, building foundations and they act as several load-bearing structures. Over time, due to environmental conditions, and based on the constituent materials used, concrete materials are subjected to a great degree of distress. Corrosion of the reinforcement bars due to chemical influences, uneven base, earthquake, drying shrinkages, and alkali-aggregate reactions are some of the reasons for concrete distress.
