Calculation of a HEA or HEB beam with a span of 3 metres, a distributed load of 4 tonnes

Simulation Generality
1

I am trying to define the cross-section of a metal beam (HEA or HEB of 160 or 180) without deflection or very small, support points 3 meters, distributed load 4 tons.

Thank you in advance.

See this link Very well done for beam calculation

a grid to fill in ;-)

Hello, for a beam of 3m long and 4 tons evenly distributed on the beam, non-recessed beam (just supported at the ends:

HEA 180: 2.7mm  boom (beam weight: 106.5Kg)

HEB160: 2.7mm boom  (beam weight (127.8 Kg)

Formula: f=(5*q*l^4)/(384*E*I)

with:

f :arrow in cm

q=4000kg

l=3m

E:2.1 (Young's modulus for steel)

I : Max moment of inertia in cm^4

Oops, I had forgotten this post, I had started something with RDM6 see attached.
