Bridge Grating in STAAD.Pro
Bridge Grating in STAAD.Pro
(OP)
Hi dear STAAD.Pro experts!
It will be great if anyone can help me on the following problem:
I'm trying to model a bridge shown in the attached file.
The bridge construction has 2xHE1000B as main beams (24 m) with centre line 3.6 m and transverse beams with centre line 1 m.
The bridge deck is of steel grating 80 mm thick.
1) Is there a way to model the steel grating. The problem is that I can't use FE meshing to
generate plate elements because grating is not massive.
2) Is there a way to place the wheel loads in the mid span as shown 0.5 m from guard rail?
Please adivce!
Best regards
Bill

Thanks, would you please confirm this assertion?
If I get you right you mean:
Hz=(12.Iz/b)^1/3 (Strong axis)
Hy=(12.Iy/b)^1/3 (Weak axis)
Average height h=0.5*(Hz+Hy)
Is this correct?

That is correct.
