A $6"$ simply supported Tilt$-$up wall panel with #$5$ bars at $12"$ on center each way $($centered in wall$)$ with $f^{\text{'}}c=3500$ and fy $=60$ksi. The clear span equals $25$ feet, subjected to an unfactored wind pressure equals $30psf$ and unfactored Dead Load and Live Load as shown.

Find the following:

Vertical stress versus allowable stresses criteria.

Nominal Moment Capacity ${}_n$ as well as $M_u($using equation $14-6$ in handouts$)$ including P$-$ effects and ensure the capacity exceed the moment demand.

${}_s$ due to service loads and compare it to ${}_s$max.
