Never dealt with this, but I would be inclined to use the combined length. Snow drifts often get quite large - I am wrapping up a design with a peak snow load of 140 PSF (roof+drift).
I believe this stepped condition may be covered in the commentary of ASCE 7-16. Take a look..
All,
I am tasked w/ analyzing an existing monorail which just so happens to be curved in plan.
I am basically planning on checking DG #9 torsion analysis via force couple in the flanges. I am not worried about this.
My question is more regarding Web Local Bending at the supports. I was...
I'm looking into the monorail design procedures.. do you combine the secondary stresses from flange bending and web tension with the primary bending and axial stresses? I'm looking at Alex Tomanavich's spreadsheet from steeltools.org, and it looks like he does not and I'm a bit concerned about...
Yes, I will be sure the frequency out of range of harmonic loading. After studying DG #11 a bit more I'm understanding the design issues a bit more. Thx all.
Agent, I am confused as to the equation to use in DG #11 for peak acceleration to compare to the limit acceleration? It seems they are...
Hey everyone - I'm new to eng-tips so bear with me! I am an EIT, one year out of school.. Not a lot of experience around here w/ vibrations so please help me out.
I am currently tasked w/ strengthening and stiffening an existing mezzanine that is having vibration and flex (due to footstep)...
