Ron,
Great advice! I've downloaded Everstress and worked through a few iterations. I've modeled a two layer system, with my 7" concrete slab sitting atop the subgrade, ignoring any extra boost from my drainage course. The stresses make sense, with negligible stress at the midpoint of the...
Ron,
The flue space is a 12" wide longitudinal space between back to back racks for fire protection purposes. The concrete slab is continuous, no holes or openings. The PCA design charts use either a single rack assumption with the same load at each post, or a double rack configuration with...
Hello,
I am designing a warehouse floor slab and the owner has requested the allowable rack load per upright. He has provided all necessary parameters, including:
- 100 pci subgrade modulus,
- 7" desired floor thickness,
- 48" x 96" rack leg spacing
- 4" x 6" baseplate size,
- 700 psi...
Guys,
Thanks for all the advice. My mix design, slab cure, and cut procedures all align nicely with these recommendations. I am holding fast on the 6" aggregate layer and allowing removal of the mesh.
I have a slab on grade design/specification for a church application that the CM is questioning from a cost savings point. The slab is 4 inches of concrete with 6x6W1.4x1.4 mesh over 6 inches of free draining granular material. The CM is requesting that the mesh be omitted and the stone...
The masonry will be designed as load bearing, mostly out of nessessity. The wall is in plane with the steel framing, so isolating the wall from the beam deflection will likely be more difficult than allowing the beam to bear on the wall.
Embeds welded to the bottom of the flange was our...
I am working on a community/family life center and we are using a structural steel framing system with infill CMU shear walls. The roof system consists of long span steel joists on steel beams, which is being done for speed of erection. The problem lies in the transfer of the shear load from...
