a) Design slab S1

b) Draw the reinforcement details of slab S1

c) Design the beam B1

d) Draw the reinforcement details of beam B1.

Beam B1 is provided with 8mm diameter stirrups @150mm c/c throughout the length.

A] Design of slab S1

$l_y = 5m$

$l_n =4m$

$\frac {l_y}{l_n} = \frac{5}{4} = 1.25 \lt 2$

$\therefore$ Two way continuous slab

1) Depth Calculation

$d_{read} = \frac{l_x}{\frac{l}{2} \times M.F }$

= $\frac{4000}{26 \times 1.4}$

= $109.89 mm$

$d_{req} \approx 120mm$

Overall Depth

$D = d + c.c + …
