Thanks Rickfischer Now I got it, it is a great help.

Hi guys I try to extract bending moments (M11, M22 and M12) from the shell element from ANSYS workbench. I able to obtain deformations and stresses, but not plate moments. I must have missing something in the ANSYS workbench. Can anyone shed some light on how to get the plate moments. Thanks...

Setup a custom polar coordination system (R and Phi) at the centre base of silo could be a handy way to apply wall pressure. The pressure can be applied as a function of silo height as well as angle (FEA program e.g. Strand7 allows user to input load in terms of x,y,z or r,phi,z). You...

Here is a blast design reference which related to steel structure (Link). It gives a good basic background about blast design with some good references. Hope it helps.

msquared48: The vibration screens are just supported with springs that come with the screen, but not on an isolated frame. I believe the dynamic forces specified by the screen manufacture are after their damping system. They are very small, like 2kN dynamic force in both vertical and...

Thanks Steven1, I found similar limit (10mm/s) in dynamic textbook as well, but it was related to transient vibration. Vibration screen is more like steady-state vibration, will they have different limit. Correct me if I am wrong. Additional to that, a vibration audit report was done by...

Hi everyone Writing this question to seek any advices/comments about vibration issues on an existing steel building, perhaps sharing similar experience as well. A steel building includes two vibration screens on higher levels and crushing machine at the lower level. Excessive vibrations were...

I am still beginner of dynamics. Correct me if I wrong. Duration of impact is related to natural frequency. The impact duration closer to the natural frequency will give the worst case, isn't it? Various material could change the damping ratio (C), mass (M), and stiffness (K) of blast...

Effective length for axial compression, I wouldn't consider joists as lateral restraints. If the member is subjected to large axial forces for some situations like conveyor belts with equipment loads, If I were the designer, I would rely on those secondary members in the bracing system as...

If you can get hold with these standards, it might help you. AS 2670-1983 or ISO 2631 Vibration and shock - Guide to the evaluation of human exposure to whole body vibration
