    External Force on Tank Shell

    thread1452-332421 I am designing a platform support bracket which will attach to a thin-walled tank. Can anyone offer alternative methods other than the one's listed in Soln's post referenced above? Soln, were you ever able to find a credible source for an alternate design method? Thanks in...

    ASCE 7-10 Tank Wind Loading - Fig. 29.5-1: D/SQRT(qz)? OR D*SQRT(qz)?

    All, I am trying to get the wind loading for a tank. In ASCE 7 (past and present) it appears in Figure 29.5-1 that the designer is to multiply D*√qz. However, in a reference webinar I was looking through he divided D/√qz. I have attached a screenshot of the webinar example. So should I divide...

    Metric Sizes for ASTM F1554 gr 36 Anchor Rods

    No, "correct" is the word I would use to describe the anchor rods that my client (who pays for them) wants. We tried the soft conversion route and if they have their reasons to want exact metric sizes then I will (and must) respect it. In other words, the "correct" choice is always what the...

    Metric Sizes for ASTM F1554 gr 36 Anchor Rods

    BoltExpert, thank you very much for your response and expertise. I guess we will have to rework our specification and look to international vendors in order to obtain the correct anchor rods

    Metric Sizes for ASTM F1554 gr 36 Anchor Rods

    Thank you TVP. It was not arbitrary, I just didn't give a great deal of details. We wouldn't want to go up a size since that might interfere with the client's equipment and for many of their anchors, the closest imperial equivalent is 1/8" smaller - i.e. an M80 anchor would be downsized to a 3"...

    Metric Sizes for ASTM F1554 gr 36 Anchor Rods

    I assumed the F1554 anchor rods would be available in either imperial or metric sizes (using the F1554M designation). However, we just shifted from using imperial anchors in our project to metric sizes and after some research I can't seem to find any metric sizes available. Am I missing...

    0.6D+W Load Comb and 1.0 Factor of Safety

    Great. Thank you all. Glad to see you are still around WillisV; your answer in the old thread helped clarify the questions we were having.

    0.6D+W Load Comb and 1.0 Factor of Safety

    This old thread deals with an internal discussion we are having in my office currently. thread507-202887 In the referenced thread, WillisV states the 0.6D+W combination for overturning assumes a 10% over-estimate in the gravity load (0.9D). Does anyone have wisdom or guidance as to where this...

    Recommended Online Structural Engineering Schools?

    Thank you very much! It is refreshing to hear from people who are actually enrolled in online structural grad schools because I have had a good deal of resistance from other fellow engineers. I have heard it all from I "should get an MBA instead" to "you don't learn as much in online classes". I...

    Recommended Online Structural Engineering Schools?

    Thank you all for your responses. STLstruc I would love to hear your insight about the reasons to pursue or not pursue and about your experience with distance ed. Going back to school could be tough for me to juggle because I'll be supporting my future wife financially while she is in grad...

    Recommended Online Structural Engineering Schools?

    I have been working as a structural engineer for several months now. I am considering going back to school online to get my master's degree in structural engineering in order to gain a better understanding of my work. Can anyone recommend a reasonably priced school which has a good online...
