HOJA DE CALCULO DE MOMENTOS RESISTENTES Y/O AREAS DE ACERO NECESARIASPARA UN ELEMENTO CUYA SECCION ESTA SOMETIDA A FLEXION PURA

Datos generales

Simbolo Und DENOMINACION:

b = 30 cm base de la seccion

h = 70 cm Peralte de la seccion

d = 61 cm Peralte efectivo de la seccion

r = 9 cm Recubrimiento al eje del refuerzo longitudinal - traccion

d'= 9 cm Recubrimiento al eje del refuerzo longitudinal - compr.

f'c = 210 kg/cm2 Resistencia del concreto a la compresion

fy = 4200 kg/cm2 Resistencia del acero a la traccion

Resultados…Viga simplemente Armada

As min = 6.10 cm2 Area de acero minima en traccion

B1 = 0.85 Factor de la zona de compresion del concreto

Pb = 0.0213 Cuantia balanceada de viga simplemente armada

Sismica 50% Pb

Asismica 75% Pb

Z= 0.75

Zona= Sismica

50% Pb 0.0159 Cuantia maxima permitida por el RNC

As máx = 29.17 cm2 Area de acero maxima segun la seccion

DISENO DEL REFUERZO LONGITUDINAL POR FLEXION

PARA VIGA SIMPLEMENTE ARMADA

Mu = 30.44 Tn.m Ast = 16.25 cm2

a = 22.88 cm.

a_max= 22.87 cm.

Recomendación: Ok Usar Ast
