    Concrete column saw cut spiral reinforcing

    Hopefully this is the correct forum... I have a demo contractor that was to cut away a concrete beam framed into a round concrete column. The building is about 80 years old. A demo saw was used and the angle was wrong, they cut through the spiral tie reinforcing, about 40" of vertical length...

    Hollowcore Plank Arrived Cracked

    Thanks everyone. It turns out there are only a couple with cracks, the person that relayed the info to me was over-reacting just a little. As JAE said, we put the issue back in the hands of the manufacturer, only because we can. It shouldn't be a problem, there is no full width support issues...

    Hollowcore Plank Arrived Cracked

    48" wide, 8" hollowcore planks arrived at jobsite this morning with approximately 1/3 of them have at least one crack in the top surface aligned with the cores. Contractor said it is typical, but I've never seen or heard of it happening before. I can't seem to find any guidance on how to...

    Stair Nosing

    The nosing also buys you an extra inch. If the code says you need 11 inch wide treads, this will include the 1" overlap for the nosing, so in essence, your risers will only need to be spaced 10" apart.

    New York 2007 Code Snow Loads - reduced??

    I didn't know that the City uses a different code than the rest of the state. I'm talking about the State code which is in its second issuanc that is based on the IBC. Nothing else changed very much except for the snow load map. The calculations are the same as in ASCE 07, but we have a...

    New York 2007 Code Snow Loads - reduced??

    I think global warming is going to make snow worse for the Tug Hill and other lake effect regions...if any more snow will even fit on the ground there. Brace yourself PT999, loading on Long Island went from 45psf for Pg to 20psf. See why I'm having a hard time with it?

    New York 2007 Code Snow Loads - reduced??

    The issue I'm having is the changes from the 2000 to the 2007 building codes. They are both based on IBC. Most of the reductions are only 5psf for Pg.

    New York 2007 Code Snow Loads - reduced??

    I'm trying to figure out why the ground snow loads in the new New York State building code are lowered in a majority of the state. I am having a hard time designing to the lower loads, like I'm missing some calculation factors that bring the roof loads back to the old numbers anyway. Does...

    It's like I didn't leave my last employer

    My old boss is telling his clients that I'm on a leave of absence, when in fact I'm starting my own company. He is aware that I'm not coming back. On top of that, my email account is still active and he has been receiving those emails for the last two months. I've been trying to see if this...

    Air Content below Spec - Foundation Wall

    I typically specify 4%-6% air content in foundation walls, upstate NY so freezing is a problem. I just got some concrete test results that show some of the trucks have air contents as low as 1.5%. Does anyone have any suggestions on how to fix this without having them remove all the bad...

    Vertical cracks @ grout locations cmu basement wall

    Thanks for the responses, my answers: 1. It was above freezing during the day, probably right around 40, and was mid 20's at night. I am guessing, as I wasn't involved with this project until this point. The contractor's memory is a bit, how do you say..."hazy" 2. We only have state code...

    Vertical cracks @ grout locations cmu basement wall

    This residential basement wall is showing vertical cracks, full height, in nearly every filled core. I am under the belief that the grout froze and expanded before it cured. I'm in upstate NY and this was done around 2 weeks ago, so freezing temps is highly likely. 8" wall, reinforced at...

    Cub Scout Presentation

    My coworker just made a presentation to 6th graders the other day. After explaining all the stiffness matrix mumbo jumbo :-) he pulled out the twizzlers to explain compression and tension and slenderness. Showed how the compression capacity increased as they took bites out of the twizzlers...

    Has anyone used "pin" at bottom of cmu wall in metal building?

    I didn't want to ask the question of why a school will be built that way. I thought what we were using it for, a tank maintenance facility for the national guard, was inappropriate. Thanks again.

    Cub Scout Presentation

    The guys around me are wondering why I'm laughing... They understand, but they don't want to. All they get out of it is that we don't need to bother with all the bracing and shear wall nonsense and just use moment frames for everything :-)

    Has anyone used "pin" at bottom of cmu wall in metal building?

    Thanks for the response. Our situation is a little backwards, this is a design build project and we already have the metal building designed. We are stuck with H/100. I have one question on your example, were the exterior walls anchored metal building so they moved with it?

    Cub Scout Presentation

    I always liked the lateral system demonstration of taking 4 popsicle sticks and put a tack in the corners to form a square shape with "pin" connections at the corners, and show how easy it is to "rack" the model. Then make another one and glue the corners to represent moment...

    Has anyone used "pin" at bottom of cmu wall in metal building?

    NCMA perscribes flashing to break the bond at the bottom of a cmu wall in a pre-manufactured building to in effect create a pin connection. This is required to account for the H/100 drift that the metal building engineers design too. We would like to use this detail, but we need supporting...

    RAM ADVANSE PROGRAM

    Our office has been using RamAdvanse and other Ram packages for the last 3 years and we have moved to them almost exclusively. The time saved using these over STAADS is incredible. Advanse has more than enough options and customizations for general building design. I concur that the tech...
