0.80*L = 8.17 m

Consideramos por medidas arquitectónicas:

Placa 1 = 4.75 m (incluidas las columnas)

Placa 2 = 3.50 m (incluidas las columnas)

Total = 8.25 m

Vu = 38.42

hm = 10.8

Lm = 4.15

F = 52.28 T

As = F/fy = 12.45 cm2

Vc = 0.53*t*d*f'c^0.5 = 63.75 T

Vu > φVc 245.25 T

Vs =Vu/φ - Vc = 103.35 T

s = Avfyd/Vs = 19.16 cm
