METRADO DE CARGAS
Peso Cobertura = 3.66 Kg./m2
Peso Estructura Metálica: 20 Kg./m2 (Verificar)
Carga Viva: 30 Kg. /m2
Área Tributaria: 5.4 x 2.833 m2
CARGA MUERTA
PD = 23.66 x (5.4 x 2.833) = 0.362 Tn.
CARGA VIVA
PL = 30 x (5.4 x 2.833) = 0.458 Tn.
CALCULO DE LA VELOCIDAD DE DISEÑO
H=9m
Vh = V (h/10) ^0.22 = 70 x (9/10) ^0.22 = 68.4 Km/h < 75 Km/h
Vh = 75 Km/h
CALCULO DE LA PRESION DEL VIENTO
Ph = 0.005 x C x Vh^2
Par superficies Inclinadas: C = +0.7 y -0.3 en Presión y Succión (Barlovento) y C = 0.6 Succión en (Sotavento).

PRESION EN BARLOVENTO
Ph = 0.005 x 0.7 x 75^2 = 19.69 Kg. /m2
Pw = 19.69 x 5.4 x 2.833 = 0.301 Tn.
Pwx = Pw Sen 30 = 0.301 x 4.9 /8.2 = + 0.180 Tn.
Pwy = Pw Cos 30 = 0.301 x 8.5 /8.2 = - 0.312 Tn. α=30º
SUCCION EN BARLOVENTO
Ph = 0.005 x 0.3 x 75^2 = 8.438 Kg. /m2
Pw = 8.438 x 5.4 x 2.833 = 0.128 Tn.
Pwx = Pw Sen 30 = 0.128 x 4.9 /8.2 = - 0.077 Tn.
Pwy = Pw Cos 30 = 0.128 x 8.5 /8.2 = + 0.133 Tn.
SUCCION EN SOTAVENTO
Ph = 0.005 x 0.6 x 75^2 = 16.875 Kg. /m2
Pw = 16.875 x 5.4 x 2.833 = 0.258 Tn.
