    Doing Simple Stuff in AutoCad 2012

    Mike has me interested in looking at Turbocad. My work is all 2D structural and civil, mostly structural - and no BIM or 3d required. Back when I learned Autocad, it was version 11, and I found the improvements through 2000 to be easy to learn coming from 11 forward. Even 2006 wasn't that...

    Split Sonotube to Install Around In-Place Bar?

    dik, I had to look up "sprue." Ralph, I like your idea of stopping the pour short of the top, and using a self-consolidating concrete for the rest. The amounts would be small, probably mixed in a bucket, and added after the regular concrete had begun to set (maybe an hour).

    Split Sonotube to Install Around In-Place Bar?

    Consolidation at the top of the pier, below the beam, is definitely an issue to deal with. I'll consider your suggestions.

    Split Sonotube to Install Around In-Place Bar?

    Hi Ralph. The form diameter is 12". The grade beam is 10", and the excess width of the pier will be toward the exterior, which will facilitate pouring from above, with some cutting on the top of the form and a make-shift funnel. I ran the hoop stress numbers, and can manage using 175 lb...

    Split Sonotube to Install Around In-Place Bar?

    Thanks, Ron. The piers will be 6' long, 12" diameter. Duct tape the inside(?) That would be impossible, I think. Where have you seen this method used?

    Split Sonotube to Install Around In-Place Bar?

    I'm trying to figure a way to install piers between a reinforced concrete grade beam above, and competent rock below. Reinforcing for the pier will be a single number 9 bar, doweled into the existing grade beam. After the bar is in place, I will have to put the sonotube around it, and the only...

    How to Protect an Innovative or Proprietary Design?

    dhengr, you are probably right that the pursuit of patent violations would probably not be worth the trouble and expense - and that the best way to protect the design would be a combination of giving the appearance of analytical magic, throwing some misleading spandrels in, and generally keeping...

    How to Protect an Innovative or Proprietary Design?

    I did a little more reading - it seems a copyright would only apply to my plans, not to the the assemblies that are detailed in them. So that leaves a patent - or some other avenue I have yet to learn of. And again, I'm not sure if it is patentable, because my write-up on the invention would...

    How to Protect an Innovative or Proprietary Design?

    Well, I could challenge their patent if I could demonstrate that I had the idea before they submitted, but that wouldn't do me much good. But I do need some kind of protection - a copyright, or something. I figure that there might be something easier than a patent, considering that all I...

    How to Protect an Innovative or Proprietary Design?

    Awesome idea number two there. Supa cheap. Conditional patents are essentially "placemarkers" that do the same thing as your post office idea. They expire after a year.

    How to Protect an Innovative or Proprietary Design?

    I've put a great deal of time and thought into an innovative retaining wall design, and am about to implement this design for the first time on my own property. This design is my baby, unique as far as I can discern (and I've really looked) and my objective is to employ it repeatedly as a...

    Detail for Wood-Framed Floor over Rock(?)

    csd72, do you have a link for that kind of product? I'm not familiar with it.

    The Structural Engineering Profession (Structurals/Civils only please)

    csd72, I feel ya. Allow me to depress you further. Before I was licensed, I worked for a small firm in WA state. There was a senior engineer there that would drop by my office, and see me working furiously on pages and pages of calculations, doing all I could to achieve efficiency of design...

    Detail for Wood-Framed Floor over Rock(?)

    msquared48, In Dallas, you wouldn't want to insulate the basement floor, because at that depth, you have a 70 degree earth temperature, which would aid in both summer cooling and (mild) winter warming. csd72, for putting a basement below an existing pier and beam home, with the right design...

    Detail for Wood-Framed Floor over Rock(?)

    I definitely do not want anything in the "crawl space," so hvac is not a concern. Supply and return air will be handled elsewhere. Those clearance issues should be addressed by, one, using treated wood appropriately, and two, the continuous vapor barrier. The IRC requires those distances only...

    Detail for Wood-Framed Floor over Rock(?)

    Fair question. I guess the main difference is in the overall depth of the system. A regular crawl space/pier and beam system has the depth of the piers above ground, plus the depth of the girders, plus the joists, which usually means an overall depth of almost 36". Also, drainage is less of a...

    Detail for Wood-Framed Floor over Rock(?)

    I'm working on an innovative basement design for existing homes, with an emphasis on speed and economy of construction, in addition to long-term performance. The basement floor will bear on competent grey limestone, and will support interior columns, but will not support the perimeter walls...

    Please Explain Subcool/Superheat Vs. Ambient Temp

    Ow, you guys hurt my head. Thank you very much for your thorough responses. I'll need some time to digest them before I can respond. Chris

    Please Explain Subcool/Superheat Vs. Ambient Temp

    I'm just a dumb civil/structural, so please forgive my ignorance. A residential split AC system is clearly intended to operate over a wide range of ambient outdoor temps. Here in Dallas, we can expect a system to run from 78 degrees to 112 degrees F. I know that excessive subcooling or...

    Would holes in flat surface increase net pressure?

    Thank you for the informative answers, particularly those of 40818. 40818 mentions the increase in pressure against a wall near the boundaries; this phenomenon is addressed in ASCE 7-05, which governs structural loads, by labeling "end," "interior," and "corner" zones. These zones are defined...
