Determine what is being required in the following problems showing complete analysis $($provided with

diagrams and$/$ figures$).$

PRPOBLEM

The supported edges of Panels $1$ and $2$ in the floor system shown may be considered fixed inasmuch as

these are monolithic with their supporting beams. At all supports, top bars, $12$ mm diameter bars spaced

at $125$ mm o$.$c are places perpendicular to the beams. The bottom of the slabs has been provided with $12$

mm diameter bars spaced at $200$ in the short directipn while $250$ mm o$.$c in the long direction. The slabs

are $140$ mm thick.

Assume that the centroid of short direction bars is $30$ from the face of concrete under tension while those

in the long direction, $42$ mm $.$ Use $f_c^{\text{'}}=28$MPa and $f_y=276$MPa.

Locate the critical yield line pattern $($failure mechanism$)$ for Panel $1$

Determine the magnitude of the largest uniform load Wu $($in Kpa $)$ that panel $1$ can safely sustain.

Locate the critical yield line pattern $($failure mechanism$)$ for Panel $2$

Determine the magnitude of the largest uniform load Wu $($in Kpa $)$ that panel $2$ can safely sustain.
