    embedded corrugated anchor bolt sleeve

    Thank you for the response ... I think the key search term was "post-tensioning duct " instead of sleeve. And indeed it looks like the best candidates are from Europe.

    embedded corrugated anchor bolt sleeve

    We are having a hard time finding an embedded pipe sleeve that matches the requirements from an equipment vendor for the installation of their anchor bolts. The size is shown in the attached file. The specified requirements are: * corrugated * 220 mm in diameter (8.66 inches) * various...

    Atlas Cavity Decking Safeload Tables

    Thank you for the insight. Yes, I am aware of the possibility / probability of the issue you stated. Still hoping to see some data from the vendor, and it looked like the referenced 2007 eng-tips post may have shared some of that info. THANKS AGAIN

    Atlas Cavity Decking Safeload Tables

    I have seen in another topic (that is closed from 2007 - thread507-177268), that previously some info was shared from vendor catalos of the mid-1970's, specifically an " Atlas-Turner catalog " ... if anyone has info on that, that could be shared it would be greatly appreciated. What...

    Coefficient of Friction b/w Concrete and wood chips

    I have an application of providing dead weight for a temporary hold down, such that the load on the concrete counterweights is to resist a horizontal load for a temporary situation (a week). I plan on being able to have a very conservative factor of safety, but does anyone have any thoughts on...

    New Steel Beam to Existing Concrete Column connection Design

    Thanks to all that have responded. Couple of responses to the comments: • I too thought perhaps an analogous design comparison could be a shear friction design for column bases. • Seismic loading is minimal. Wind loading would control, but minimal at this location as well (compared to dead and...

    New Steel Beam to Existing Concrete Column connection Design

    Please refer to the attachment. It shows a new steel beam being connected to an existing concrete column; however the connection does not rely on post-installed anchors into the concrete column, but rather a steel plate on either side of the concrete column and clamped to the concrete column...

    new anchor bolts to thin concrete wall panel (one side inacessible)

    I have an application where I need to add anchors bolts to an existing precast concrete wall panel (two inch thick concrete double tee flanges). The purpose of the anchor bolts is to add wind suction resistance for the all panels and connect back to exisiting concrete beam girts. What I was...

    stainless steel grade and welding to carbon steel

    do you have some reference materials or websites that I could forward to the clinet, for they are pretty well set on stanless steel.

    stainless steel grade and welding to carbon steel

    Thanks for the response and appropriate questions ... I contacted the Owner today and he informed me that the water is "Muratic acid and maintain the pH between 6.0 and 7.0". Hope that helps?

    stainless steel grade and welding to carbon steel

    I have a client in an industrial application that is looking to replace a 30 year old conveyor. The conveyor was originally and currently painted carbon steel. The purpose of the conveyor is to move and simultaneously cool portions of tires under their manufacturing process. The cooling is...

    Inches to Feet-Inches

    I am missing something very very basic here .... so apologize. as a simple example, say I put the number 1.25 in once cell ... then 2.50 in another cell ... a third cell adds the two .... EXCEL would report the result as 3.75 .... if, however I wanted it to read 3'-9" via the nice and handy...

    Inches to Feet-Inches

    this is a really novice question. I have cut and pasted the formulas that have been suggested above for converting decimal numbers to feet and inches (and fractions thereof) .... but how do you get actual numbers into the given cell where the long "=IF(......)" formulas are at? I have tried...

    solo 401k

    I have a small one-person engineering business, and was looking at ways of maximizing tax deferred retirement income and specifcally reducing current taxable income. I have also recently heard about "Solo 401k" plans that are fairly simple to set up and manage. Does anyone have any...
