    Calculating load on a central beam in a residential deck

    I don't know how much actual structural design experience you have, but I know mechanical engineering teaches different courses than CE does. If you are relying heavily on your old "strength of materials" course, you are at a huge disadvantage. While it is possibly the single most important...

    CFS Shear wall without bottom track.

    It also looks like to me, "Open" means no capacity, AND the output doesn't print 0.00, it ignores output to those fields altogether. I am also curious about the low values of Force since the heading is "-Force(k )-" and not k/ft or ksf. Does that mean there is a total of 720 lbs of wind for...

    CFS Shear wall without bottom track.

    I wonder if the software thinks it is attaching to a base angle (not a track) or a lower girt that attaches to columns on each side very close to the baseplate. If the bottom is not attached to anything, what reaction or restraint that connects to the earth/foundation "attracts" the distortions...

    Metal Deck Perpendicular to Short DIrection Drainage

    ANE91, we used to use a pellet rifle on taller buildings, but that is good to drain the leak, not find the leak. Of the ones I have dealt with, really bad leaks are easier to find than smaller leaks. As you know, most leaks occur uphill of where you see them come out and you are also seeing...

    Metal Deck Perpendicular to Short DIrection Drainage

    As described, you most likely will have water issues forever, with no real good cure other than replacing the roof. Many I have seen cross-framed the joists with hat-channels or some other product and then sheet the roof with panel run parallel to joists. This is generally an unheated...

    I feel like I wasted 2 years — advice from senior engineers appreciated

    Hyde_v, You need to start "Following Through". You have not responded to anyone's questions except about 4 hours after you established this thread. I advised you to answer people's questions "in bold" on my first post. Unless something drastic has happened in your life in the last 2 days...

    Truss or not a Truss?

    Kootk, could you clarify what you mean by Ix_truss and Ix_chord. I assume they are Upper case "eyes" and not lower case "ells". I am assuming the ">>" indicates "much greater". I assume there is some Span/Depth ratio that works handily but severe deviations may not be so as predictable.

    Truss or not a Truss?

    I am more familiar with software design and debugging in general, than I am Truss software specifically. So, as they say, I don't have a dog in this fight. While I really value software and both use and write programs at times, there are some common issues I have seen multiple times. I do...

    LOL, I made the same mistake with The Beatles LSD song.

    I feel like I wasted 2 years — advice from senior engineers appreciated

    First, I'd like a little better understanding of what constitutes "here". Your post asks for help on "pushing forward" from those of us who have experienced difficulties. You have not asked for how to alter your course, but you will get advice on that too. For "pushing forward", parts of...

    Truss or not a Truss?

    I agree, even at the 4 plys, it looks inadequate. Seeing the calcs would be a must.

    Toe nailing rafters

    The use of toenails at a ridge board is common and allowed everywhere I have been, but a ridge board is not much if any of a structural member, it does not hold the end of a rafter up unlike a ridge beam.

    Bridge Ovhg Bracket question about hanger rod connection location.

    Dayton was very helpful and educated me on where Dimension A is at. It is specified at the "Bolt Holder" cut sheet. But it can be as high as 22" per the cut sheet. That is a long cantilever if you have a larger tension load coming up the vertical piece and attaching to the arm.

    Another how to fix it thread

    Now I have a real problem. I am constantly picturing a free-body diagram of a nail into air. I have 14.7 psi air pressure applied to the exposed surface of a 16d nail. If we can find a reference with the coefficient of friction between steel and air, we might be onto something. Its like a...

    Toe nailing rafters

    It is from the IRC code. I know it is in "Floor Framing" but not sure about roof framing. Due to the loadings you cited and what I am picturing, I think building inspectors might apply it to your situation. I had an oddball roof one time and had to use them on some rafters that ran parallel...

    Toe nailing rafters

    Upon reading your post, but not having a sketch to see, if you are butting the 2x8 rafters into a band, beam or packing, I thought the code requires a 2x2 nailer or hangers. I thought facenailing of any kind was no longer accepted. Am I not picturing this right?

    Another how to fix it thread

    Greenalleycat, it is a common misconception among engineers how construction workers view proper equipment usage. They most likely used an air gun. Air guns are meant to nail air. You must be thinking of a wood gun. They did properly nail the air, but usually I space air nails a little...

    Thanks jhnblgrm, both have been helpful

    Darn Architects!

    I would consider running a 4x6 through a planer a few passes to make a 3x6. That should give a "leaner look" and also give me more confidence in its longevity. I would also use Yellawood if possible. Exposed to water tends to become damaged eventually.
