Salut,

As vrea si eu sa aflu ce valori folositi voi pentru materialele introduse in ETABS.

De exemplu pentru diferitele clase de beton ce date introduceti.(daca se poate un tabel cu aceste informatii).
La Define> Material Properties etc....

Apoi pentru Otelul structurilor metalice.

Va multumesc anticipat.

Sal, eu folosesc graitec si graitecul  le are deja definite, astea sunt valorile:

Beton:

C16/20:
E=27000 MPa
G=6750 MPa
Nu=0.2 (poisson)
Ro=2400kg/m3
fck=16 MPa
fcu=20 MPa
fyk=300 MPa
fywk=210 MPa

C20/25:
E=30000 MPa
G=7500 MPa
Nu=0.2 (poisson)
Ro=2400kg/m3
fck=20 MPa
fcu=25 MPa
fyk=300 MPa
fywk=210 MPa

C25/30:

E=32500 MPa
G=8125 MPa
Nu=0.2 (poisson)
Ro=2400kg/m3
fck=25 MPa
fcu=30 MPa
fyk=300 MPa
fywk=210 MPa


Otel:

S235:

E=210000 MPa
G=80800MPa
Nu=0.3 (poisson)
Ro=7850 kg/m3
fy=235 MPa
fu=360 MPa


S275:

E=210000 MPa
G=80800MPa
Nu=0.3 (poisson)
Ro=7850 kg/m3
fy=275 MPa
fu=430 MPa

S355:

E=210000 MPa
G=80800MPa
Nu=0.3 (poisson)
Ro=7850 kg/m3
fy=355 MPa
fu=510 MPa

S450:

E=210000 MPa
G=80800MPa
Nu=0.3 (poisson)
Ro=7850 kg/m3
fy=440 MPa
fu=550 MPa
