I am working on a simple span wood beam that is overstressed and I'm toying with a few different ideas. One interesting one that I've come up with would be a good solution, but I'm looking for someone who has possibly done something similar to this.
Obviously, the wood beam (7X18 psl) is in...
Maybe I should clarify.
If the beam is cambered, should the value of the camber, say 3/4", be added to the total deflection to find the natural frequency.
So if your total calculated deflection @ vibration level (LL= 10 - 30 psf depending on the activity) is 1.25", would you add the .75" for...
Does anyone have a good anwser for how cambering a beam effects it vibration characteristics (in composite steel). The AISC floor vibration guide uses the equation fn=.18*sqrt(gravity acceleration/deflection)) to get the natural frequency of a particular beam or girder.
When a beam is...
Does anyone know of sizes or where I could find available sizes of aluminum square HSS sizes? The publication I have is from the 80's and shows the largest size as a 3x3. Any information would be great. Thank you.
Does anybody know if masonry braces the top flange of steel to prevent LTB. Are there any special details that have to be made for this to be done? I have the cmu sitting on the top flange of the steel section and I'm trying to limit the size.
Thanks
