    Unreinforced concrete design allowed in ACI 350?

    Jed, I couldn't agree more with you. The only liquid tanks that I ever designed were always reinforced to preclude tank cracking and leaking. So, while I personally didn't think it was a good plan, if the code were to allow it, it becomes an entirely different answer to the precaster. In any...

    Unreinforced concrete design allowed in ACI 350?

    Hello all! I have a question that has been posed to me by a septic tank precaster: Is it permissible to design a septic tank as unreinforced concrete? I don't have a copy of ACI 350 on hand, so I couldn't answer his question as to whether unreinforced design is allowed or not. Does anybody...

    Timber column repair with epoxy

    MiketheEngineer, The column bases rest directly on the concrete slab, which you can imagine have varying degrees of decay. There's no evidence of the posts crushing, so they can obviously carry what they need to. However, without removing the lower portion of the columns, there's really no way...

    Timber column repair with epoxy

    Gentlemen, Does anyone have any information/experience with using epoxy putties and epoxy hardeners to repair structural wood/timber? I know there are a few companies out there that sell products which claim to be able to be used in this capacity, but I've never used or specified this type of...

    Gypsum sheathed perforated shearwalls

    Hello all. Has anyone dealt with whether you can use gyp board or gyp sheathing in a perforated shearwall analysis? I can't find anything in the IBC that specifically disallows this, but I know that the testing was based on wood panel sheathed shearwalls. Additionally, the pertinent...

    Smooth Reinforcing - Concrete Design

    msquared48, Yeah, I've seen the square, twisted stuff before too. This stuff is round. It's just a bit different than I expected, based on prior experience. Regards, Steve Rivard, PE

    Smooth Reinforcing - Concrete Design

    spats, The testing guys have indicated that it's 5/8" diameter individual bars at 4" o.c., so definitely not WWF. Regards, Steve Rivard, PE

    Smooth Reinforcing - Concrete Design

    The testing agency, as I indicated above, has samples of the reinforcing and has visually observed the reinforcing in the core hole locations. It's definitely smooth. I also realize that plain reinforcing is not allowed, nor has it been since the ACI 318-63 was in force. This is an existing...

    Smooth Reinforcing - Concrete Design

    Does anybody have a good reference for the design of a reinforced concrete slab with smooth reinforcing? I'm trying to come up with a one way slab capacity for an existing slab. The testing agency has informed me that from visual observation in core holes, and the reinforcing samples that...

    Sugiyama's Perforated Shear Wall Paper

    Does anyone have access to, or know where I could get my hands on Sugiyama's paper on perforated shear wall design? I'm trying to get to the guts of these things to get a better understanding of them, instead of relying on the washed out stuff from the IBC. Any help with this is greatly...

    Steel Deck Diaphragm Attached to TrusJoist TJLX Open Web Truss

    Does anyone have any experience with attaching 1.5B steel decking to wood trusses? It certainly seems reasonable that this diaphragm should perform adequately, but if anyone had any solid information with regard to this diaphragm and fastening, your input would be greatly appreciated. I'm not...

    Clay Tile Information Needed

    Does anyone have, or know of a resource, for structural clay tile? I don't have a ton of experience with this stuff, other than observing it for pan and joist floor slab construction, so any help with this would be greatly appreciated. Steve Rivard, PE

    Expansion Joints in Steel Roof Deck

    Wale...do you know of anywhere this report can be downloaded for free, or is it only available from the National Academies Press for a fee?

    Expansion Joints in Steel Roof Deck

    Does anybody out there have any practical guides for determining whether an expansion joint is necessary/required for a bar joist and steel deck roof? My building in question is 172' wide x 304' long. Intuition tells me that something may be warranted here, but I'm not sure. Any help with...
