WL = 250 KG/m2

Wu = 1377 KG/m2Wu = 0.14 KG/cm2

a) Losa maciza en dos direcciones, con vigas de borde y sin ábacos:

Luz = 7.00 m

h = L/36 = 19.44 cm

peso propio = 480 KG/m2

Se adoptará una losa maciza h=0.20 m.

1.2 PREDIMENSIONAMIENTO DE VIGAS.

a) Para vigas portantes (VP):

luz = 7.00 m

h = = 0.65 cm

b = ((L1+L2)/2)/20 = 35.00 cm = 35.00 cm

luz = 6.00 m

h = = 0.56 cm

b = ((L1+L2)/2)/20 = 32.50 cm = 32.50 cm

luz = 5.00 m

h = = 0.46 cm

b = ((L1+L2)/2)/20 = 30.00 cm = 30.00 cm
