Problem $1$:

Design the for the four$-$span slab near the stairs in figure below using the ACI Coefficients method, considering that the slab is integrally built with the supporting spandrel beams. Where: $f_y=420$MPa,$f_c^{\text{'}}=21$MPa,$W_L=5k\frac{N}{m},W_D=4k\frac{N}{m},$ Cover $=25mm,$ use bar size no$.13$ Assume slab thickness is $150mm.$

Problem $2$:

Compute the design moments for the four$-$span slab from problem $1,$ using moment redistribution, as permitted in ACI Code
