    Embedded handrail base capacity

    Spats on thread507-333478 you mentioned using the PCI design manual to figure the embed capacity. In PCI Design manual 7th edition it's Design Aid 6.15.10 and 6.15.11. If you're doing this for a handrail in a curb or something you have much less concrete in the transverse direction, how do we...

    Bonding Solid rod inside of tube

    Thanks guys! dik are you saying use another tube for reinforcement? Is that to save on material or another reason? I think they wanted to do stainless steel instead and alumnimum main member but there isn't a way to keep the metals separate, I need them to act compositely and they will be...

    Bonding Solid rod inside of tube

    I have an aluminum member that is hollow and we need to reinforce it in order for the cantilever from the base to work. The client has proposed using a 12" solid member inside the tube and just sliding it over but as we all know I need composite action in order to make that work, I can't just...

    Hollow core precast panel manufacturer help

    Thanks for the responses. It's in Atlanta, GA. There are a few pre-cast manufacturers here that I could contact. I tend to agree with DayRooster, decline the work and push it to a precast manufacturer. Owners rarely understand how complicated it can be to do "simple" things like cutting a...

    Hollow core precast panel manufacturer help

    I'm trying to find some information on the manufacturer of this panel type. I'm going to the site to document next week I believe but wondered if anyone had an idea just based on the type of leave in forms they used and the rectangular shape. I should have dimensions to help if that's needed...

    Expansion anchors installed into top of concrete on metal deck

    Does anyone have any testing data on an anchor being installed into the top of concrete on metal deck with less concrete than is specified by the manufacturer? I know that's kind of specific but I have a project where they "have always done it this way" using 2" concrete on 2" deck but there...

    Band/Sill not bearing directly and has a gap

    structSU10 - Yes they could, I didn't think about that at all. This is why I like to try and prod peoples minds.

    Band/Sill not bearing directly and has a gap

    I have a project where the original structure is brick piers with brick foundation/skirting walls and they have some areas where the brick walls were replaced with CMU. the issue is that the sills (pressure treated) and bands (untreated) have a gap to the foundation walls below. I'm trying to...

    Adjacent PEMB Modeling Tips

    Adjacent PEMB Modeling Tips

    You can see in the file the areas. The clouded area is where the PEMB is going and the right side is the bar joist roof and steel frame going into that storefront. The heavy red line is the CMU separation. After reading your question I think I can just make a joint to make them independent. My...

    Adjacent PEMB Modeling Tips

    I have a building that has a PEMB adjacent to my building. It's all new construction and the PEMB is next to my CMU fire separation wall. The CMU wall will support steel joists on the west side and there will be steel frames in the storefront the east side. I don't want to model it as just the...

    Vaulted wood ceiling, no ridge beam, no trusses, HOW?!

    Thanks for your input. The stiffness of the walls and diaphragm makes sense. i'm not sure what is above the t&g, could be plywood, they are replacing roofing so this could be a chance to review what is there. If the beam has twisted due to drying and shrinkage what kind of repair would be...

    Vaulted wood ceiling, no ridge beam, no trusses, HOW?!

    Went out to review a structure that has a vaulted ceiling, 7 degree slope (1.5:12 approximately) 4x8 beams 6'-0" on center, 2x6 t&g diaphragm, 28' long (wall to wall) with 1' overhang at exterior walls, 18' wide (three 6' bays). So I'm already looking at this like it's crazy but the main issue...

    Truss Plywood Gusset Repair

    gte447f I looked at that and thought it would be crowded and noone would think it was a good idea. I that may be what is done to provide more nails. Would try to use 8d though so that I could fit more in. If we're installing from both sides that spacing between fasteners would be on one side or...

    Truss Plywood Gusset Repair

    Thanks. The strap seemed like a reach but just brainstorming. As far as the steel frames I couldnt do that bc my members are flat so we are installing into the narrow face

    Truss Plywood Gusset Repair

    Thoughts on putting steel straps over plywood over the chord?

    Truss Plywood Gusset Repair

    I'm replacing some of the webs members and part of the bottom chord, that's why I need this plywood gusset. Need to connect everything to transfer the load back through. I am planning on telling them to jack up the truss 3/8"-1/2" to release the load and then install the repairs. I think it's...

    Truss Plywood Gusset Repair

    Agent666 The existing truss has the last vertical web and part of the bottom chord rotted out due to bad construction practices (they didn't put any flashing at the deck and some rot took place). The trusses are 24" on center, 20 psf dead load, 40 psf live load, bottom chord 5 psf dead load. I...

    Truss Plywood Gusset Repair

    dhengr: I was contemplating the steel plates if it can get me the capacity I neeed. Hate to get into steel with these because it's residential and the contractor is going to push back on it or try to go crazy on the price. I wouldn't have as much of an issue if they hadn't put that gypcrete to...

    Truss Plywood Gusset Repair

    Thanks for those. The newer codes do have the 75% diameter for the similar materials but the spacing has gone down to 4d max for geometry factor, 3D minimum. That's a huge drop, and since the wood is old I assume that I may have to go with the larger spacings to keep the wood from splitting.
