Q. An isolated concrete pavement slab of length L is resting on a frictionless base. The temperature of the top and bottom fibre of the slab are Tt and Tb, respectively. Given: the coefficient of thermal expansion = ฮฑ and the elastic modulus = E. Assuming ๐๐ก > ๐๐ and the unit weight of concrete as zero, the maximum thermal stress is calculated as
