Typically with new construction, a multi-story wood framed building would have holdowns that transfer from the roof to the foundation. With seismic retrofit, this is different since it is only necessary to retrofit the first floor. With this in mind, the existing shear walls on the stories above...
Sorry for any confusion, I definitely do mean plaster with wood lath when I mentioned plaster. It appears that the general consensus is to use 20 psf for 2X4 wall with plaster on both sides.
Thank you all for your responses - they are very helpful. I just want to clarify that I always check with the architect for the correct assembly before estimating the dead load. My question is mainly aimed towards published references/resources that will justify a lighter dead load... 20 PSF for...
I've been designing using the dead loads from Design of Wood Structures ASD/LRFD - these dead loads would yield roof, floor and wall assemblies of approximately 20 psf. A lot of other engineers use assemblies closer to 15 psf, which is significantly less than the 20 psf for interior wall with...
Thanks for the great input, KootK.
The bearing wall is basically being supported by a 2X10 DF joist sistered with (2)-2X8s running the same direction, a total span of ~22 ft but supported in the middle by a drop beam that is perpendicular to the joists. We are looking to replace the built-up...
For a residential project that I am working on, the ceiling has deflected 3.5" due to inadequate support underneath the bearing line (poorly sistered connection with screws on the first story of a four story wood-framed residential building). We are looking to replace the joists underneath the...
