I tried simulations with different Poison`s ratio to find frequencies, and my results are:
v freq (Hz)
0,21 1,146
0,22 1,145
0,23 1,145
0,24 1,144
0,25 1,144
0,26 1,144
0,27 1,143
0,28 1,143
0,29 1,142
what you think about this results? Its...
what element you are falimiar to simulate a steel tube filled with concrete? Or questioning with other words: what element you recommend to use on my situation?
I`ll calculate my self, scam and post it here to you see. ok?
Hi, KootK.
I am modeling a transmission tower using steel tubes filled with concrete on the amounts and corner frames for every other element of the tower.
I am modeling that on ANSYS. My code for that its on attachment.
My questions is:
1) It`s correct the affirmation from Trenno to get the...
I`ll proceed with a modal analysis.
So, presuming that the concrete wont crack. How can i determinate the equivalent elasticity modulus for a equivalent composit section?
ok, but for example:
Using a steel tube with:
- 140 mm of external diameter and 130 mm of internal diameter;
- E = 200 e9 Pascal;
- DENS = 7850 kg/m³
Filled with concrete with:
- E = 26.3 e9 Pascal;
- DENS = 2400 Kg/m³
what the Equivalent Modulus of Elasticity??
