    Distribution of Cooper E80 Load

    I have a retaining wall close to a railroad, and I have figured out the vertical load using the Bousinesq equations. I was wondering how you guys add in the Vertical load? If a surcharge, do you take the whole amount, or do you distribute down through the soil?

    Roof Rafters

    Thanks. Like I said, this was not my design, just looked fishy not having blocking or bracing. Some longer spans too, looked to be 20+ feet.

    Roof Rafters

    Not sure on this, been a while for wood design. Does code require that roof rafters have blocking between them? I saw a building with looked like 2x12 rafters, no blocking at all. Did have hurricane hold downs, so this was the roof.

    Conc. Wall Dowel Bend Direction

    I wouldn't think so...how does it know which way its developed when tension is on the bar? The hook just needs to be developed properly in my mind.

    Floating Floor

    Is that about a 8' span?

    Precast Panel anchor problem

    I wouldnt think that cutting rebar would matter, i would put the anchors at the top and bottom, depending on the look, the bottom could just be a pin into the footing, and not into the wall. At the top, who cares, the moment is 0ish, thus no cracking to worry about? How tall are the panels

    Floating Floor

    Glass isnt especially good in tension, so not sure how you would get that to work....I guess plans will be the storyteller

    K-Web

    I would start with the supplier, or mfg. of it. I googled it and didnt find much. Try Duro wall, they make some too

    Precast Panel anchor problem

    I would not use drill in anchors. use Embed plates cast in. If this is existing, and you have to drill, core drill and use epoxy type anchoring system

    Find capacity per foot & deflection of 8" high Al Channel

    Is there anyway you can use steel, and isulate it from any induction heating?

    Opening in existing cmu - concrete lintel?

    Why not a precast lintel, pour before and lift into place and grout? You could form it up on site to fit perfectly.

    Wall Bracing

    dcarr827775, look at it when in tension, the vertical component of the angle is going to cause bending of the angle at the bolt.

    Wall Bracing

    I Agree, wouldnt you have a vertical and horizontal component at the end of the angle? It would cause some bending on the leg

    Wall Bracing

    No attachment

    inserting masonry dowels

    So your wall is unreinforced, but there are bars shown going into the footing? how tall are these bars?

    flexible diaphragm

    Could you ever get plywood to be rigid?

    Lean Concrete

    What weight do you guys use for Lean Concrete?

    URGENT, PLEASE COMMENT

    I dont see how you even know what the strengh is. Certainly they are not going to remove it based on your word, and not wait for the engineer. Long term, it might be that the design doesnt work, i.e. after 28 days, etc. For now, let it cure, cure it correctly and see what you get in 28 days...

    URGENT, PLEASE COMMENT

    I wouldnt worry about it today, they are not going to remove the forms today correct? Long term might be an issue, but for the next couple days till the engineer returns, it will be curing and not achieve the 200kg anyway.

    Light Pole Recall

    JLNL, Wouldnt that be taking on all the liability too? I suppose thats the case. I would want to steer clear of it, just wouldnt want my name associated with it.
