    Hand Rail Post Embedment Depth

    suggest a turned down edge or pocket for post with a U bar around post into slab and adequate cover...concrete usually fails by cracking edge off slab caused by corrosion of post. Use caulk around post base to keep away water and salts.....never happens!

    San Antonio slab

    small? 1" differential movement?? existing soil conditions have 3"-6" movement but will remove and replace top 5' CH layer and have a 1" PVR which I have seen in some other literature and assume thats teh best you can hope for down there without big expense. Looking for design guidance for...

    San Antonio slab

    what is typical design for expansive clays in light loaded commercial facility...I assume integral gradebeams and slab. Any suggestion for design guide...PT not in the budget or design scope, only rebar. Building is about 100' square with a couple column loads and ligh bearing wall line load...

    Open Caisson design

    after some thought, it is simply a compression ring and the compressive stress is very small on concrete walls. Tip design is most critical as the cutting shoe must be durable and not shear off and take ring compression as well as ring tension when the plug is made. Then the bouyancy after the...

    Flagpole Wind Loads

    Analyze this! I bought a flagpole for MIL for Christmas. They said put 10% of the length in the ground in a hole the same dimension in width and fill with concrete (cuz that's what the directions say). I bought a 20 foot pole with a 3'x5' flag, so I'm using a 2'diameter by 2' deep hole with...

    Land area calculation spreadsheet

    Is there such a spreadsheet? Don't need a CAD program or survey program. More like a math program. We did area calcs by hand in school....somehow by putting in angles and distances.

    Need spreadsheet for land area calculation.

    Here's a better one, http://www.vbdesign.net/expresso/showthread.php?s=&threadid=3588 just wish I was a programmer. Barely remember my Fortran 77! Can I list my points px and py in a spreadsheet, then have this sub read and calculate the area? Since my points are generated by angles and...

    Minimum Reinforcing of Pedastal

    Obviously, it wouldn't be prudent to build a 200,000 gallon water tank on unreinforced pedastals in my opinion! On the other hand, I do not see where it says "pedastals" have to be reinforced at all, only 0.005Ag across the "interface between pedastal and footing". ACI said...

    Preformed Waterstop (Bentonite vs adhesive joint sealant)

    We use Synkoflex on existing (old) prepared concrete and PVC serrated on all new concrete at all treatment plant projects. Haven't used bentonite materials for years.

    Minimum Reinforcing of Pedastal

    This is a waste of time to me but I have to resolve this question forced upon me by a Contractor's interpretation of ACI 318. This concerns 46 inch square "pedastals" for a six legged water tank structure. My interpretation: Use ACI 318 -10.8.4 and 10.9.1 for compression members and...

    fall protection

    Thanks for the tips. I understand the basics. We're replacing a line strung down the middle of the building. In one case, I think were stuck with a cable because we have a very high arched truss for the hangar and no lateral bracing other than more cables. In the second hangar, we have a...

    Asphalt Pavement Design for Truck parking area

    Is there a guide or info available for truck parking areas? Is there info avaialble about delayed use of parking area until pavement "sets"?? Anything I can do/use in the pavement design to keep trailer jacks from sinking (other than using concrete or steel plates)???

    Fastener strength

    What is the strength for a hex bolt fastener with markings A,F,X and O in the center. It is in an aircraft hangar so it may be an aircraft bolt.

    Parking Garage Water proofing

    Several contractors we have worked with only use Lymtal products. So it must be economical and provides renewable 5 year warranty periods. http://www.lymtal.com/

    Found it. Thanks for the tip. Just what I was thinking.

    Stainless NDT spec

    Is there an ASTM or AWS spec for proper dye testing of 12 ga stainless sheet fusion welds? We're field assembling a continuous water tight gutter trough for a swimming pool. I don't have any AWS codes other than 1.1. I believe 1.6 is for stainless. Thanks.
