    lapsed PE license experience?

    Working with an older engineer who is looking to get his lapsed PE back to active. He's a retired guy who comes in for some small jobs, keeps him busy and never hurts to have experience like that even on local culvert sizing. He's 5 years lapsed. Anyone ever work with their state to get a lapsed...

    name for these triangle plates used to strengthen moment capacity at welded connection?

    name for these triangle plates used to strengthen moment capacity of welded connection? I currently estimate the moment capacity of these connections as if the plate is not there. Working to see how I can take these plates into account, I assume the moment capacity with is stronger than without...

    only see basic loads on selected plates?

    I have a concrete storage tank modeled out of plates and I want to visually see how the wall loads in a certain basic load case are being applied to the tank. This interior fluid load is applied to the walls and the floor, therefore it gets a bit messy visually when looking at this basic load...

    Stone armoring under storm water pipe inlets and outlets

    What has me wondering is I nearly always see the bottom of a pipe inlet or outlet armored with rock (apron as I call it) and then only sometimes see up the sides and on top of the culvert armored. This is in agricultural drainage work, commercial developments, drive culverts, and road projects...

    What is a "hairpin"?

    I have been seeing "hairpin reinforcement bar" and "hairpin foundation" in the area of metal building and their foundations. Appears to me to be a horizontal bar that ties a slab on grade to a concrete foundation, heard this is the "cheap" way to do foundations for metal building systems. Anyone...

    Upstream Ponds - How Would You Account for Those (If At All) Without Modeling Them?

    What about this? Estimate area of pond and swamp areas spread throughout watershed using contour map and your local knowledge. Use Table 4-2 from TR55 June 1986 to obtain a pond and swamp adjustment factor, Fp. Multiple your current peak flow by this Fp to obtain a smaller peak flow. I do not...

    ASTM D5312(freezing/thawing rock) map with freeze thaw cycles for places outside US?

    Anyone have a map or way to come up with number of freeze/thaw cycles for durability testing of rock for those of us north of the US? Anyone using this standard for rock testing in Canada? ASTM D5312, Evaluation of Durability of Rock for Erosion Control Under Freezing and Thawing Conditions...

    Soil Segregation

    I have seen segregation in aggregate stockpiling operations. I have heard of segregation occurring when material is dumped from too high of height, one instance was a trench for a new sand filter in a dam. I read there is chance of segregation when loading trucks with conveyors. I have not...

    Soil Segregation

    1. In a general sense it seems to me gravel segregation results from a sorting of the particles based on size, mass, shape, or combination thereof and is generally undesirable. A sorting mechanism I have seen is stockpiling of gravel. In the process of stockpiling larger particles tend to...

    Correct understanding of tensile reinforcement in cantilever wall?

    good point. I can see how this could be dangerous, leave out crucial information and I could arrive at the wrong conclusion. I don't mean to ignore equilibrium here rather I aim to take on my misunderstanding in small steps, ignoring certain concepts at first. In statics we ignored the...

    Correct understanding of tensile reinforcement in cantilever wall?

    Thanks hokie, BA, and HotRod. Working to understand some reinforced concrete wall design, thinking about these fictitious walls and hoping to find where my thinking is wrong. updated the previously attached pdf 1. I updated the steel to show it only extending to the lower mat. No bends or...

    seeking feedback on my pocket penetrometer cheat sheet

    Got a pocket penetrometer and made this "cheat sheet" to help me in the field. Looking for feedback from those familiar with this tool, I have not used it in the field. From reading not really sure what value it has or when I would use the readings. Looking for other things that might be handy...
