How does one check if web stiffners are required? I checked if they were needed due to shear which they weren't. The only other design work I was taught with them is if your factored load strengths are greater then your limit state's strengths then you can alter your Lb by placing web stiffners...
The only reason I initially went that route is because there is an existing one that is made similar with the open flange/open web area which handles the 60 kip truck beds. However the beds I need to lift are wider and larger so I explored that option.
And my "hanger" is a 200 ton capacity...
However, what exactly should I be concerned with?
Lateral torsional buckling seems to be the determing factor between LTB, WLB, FLB and Yielding as the beam itself will be compact.
Also checked max shear and deflection and both were fine. Again the scenario is a beam connected to a crane hook...
Alright I found a design guide for web openings of this type however it does not describe how to include the fact that I have a flange opening as well. Are there any design aids that may help me with that or do I just try and adjust my unperforated values accordling.
Ever heard of being thrown into the fire?
Hiring it out to some one else is not an option. I do have a structural emphasised civil engineering degree from one of the better engineering schools in the nation and am trying to take all neccassary procations to make this safe.
I am simply asking...
I am designing a strong back beam that will be holding a 100 kip truck bed up. The beam must be lifted by a crane and there are severe height limitations on the overall system so a oval shape must be put in the center of the beam in the web. It needs to be 20" in depth and ranges from 5" to 8"...
I have a steel box roughly 20 X 20 X 20' containing a liquid that is roughly 240 lb/ft^3. The box will be welded at our shop but I am unsure of how to make sure the box itself can withstand the forces subjected to it by the fluid. My main concern is the lateral pressures on the sides might be to...
