Consider a concrete slab $30\text{'}(9\mathrm{.}14$ meter$)$ by $12\text{'}(3\mathrm{.}66$ meter$)$ and $8"(203$ mm$)$ thick,

subjected to a temperature differential of $).$ If you assuming $k=200$pci

$(54\mathrm{.}2$ MN$/$m$^3)$ and alpha $($thermal coefficient$)$

$m\frac{m}{m}\frac{m}{C}),$ the determined maximum curling stresses in the interior and at the edge

of the slab will be nearly:

Interior stress $=238$

Edge stress $=214$ psi

Interior stress $=232$

Edge stress $=208$

Interior stress $=208$

Edge stress $=232$ psi

Interior stress $=214$

Edge stress $=238$
