I am looking at an existing building with composite metal deck and composite beams (shear studs). I am looking at the floor for some additional equipment to be added. From this I noticed that the composite deck capacities from Vulcraft and New Millennium vary quite a bit. The floor system is...
I have been asked to design reinforcement for a HSS column that needs the face notched out.
This is a freestanding platform in an industrial building. The platform is 14 ft tall and has angle kickers for lateral stability. The column to be notched is a HSS 6X6X1/4 and the notch will be on one...
Assuming you meet any prescriptive code requirements and connection design requirements etc how do you optimize a moment frame? It seems to make sense to me that you would want the moment of inertia of the beam and column to be roughly equal except in high seismic areas where you need strong...
I have a project near the coast in South Carolina. I am under 2012 IBC with a wind speed of 130 MPH. I plan on having a bypass metal stud system for the exterior walls. The walls are cladding only, my primary lateral system will be moments frames. Are there any prescriptive requirements for...
We usually do a couple 3 story wood framed apartment buildings a year. I have always designed these with segmented shear walls and had hold downs at pretty much every corner and wall opening. Recently contractors have been complaining about the cost of this system. To limit the amount of hold...
I am starting to get more projects that are under the 2012 Energy Code. Normally I don't bother with this and let the Architect figure it out but with the new code it seems there is a clause to have continuous insulation. From what I have been told this means that the insulation between the...
I am looking at a typical metal stud boxed header with (2) studs vertical and a track on the top and bottom. What do you consider the unbraced length for bending? Do you assume the top track fully braces the compression flange of the studs? I have always considered this unbraced unless I add...
