    Discussion: The Miracle Of The Loretto Chapel Staircase Explained

    Yes I have seen it in person. Quite impressive and interesting. Don't really have any detailed insight into the construction.

    Is mill steel sections isotropic or anisotropic?

    at first order steel is isotropic, which is good enough for most design purposes. when one looks very closely, with very good test methods, steel like almost all metals is anisotropic in stiffness and strength.

    Aerospace is 90+% #1.

    41 Years old looking to go back to school to receive MS. Looking for advice!

    I got my Master's going part time (in-person classes) while working full time, in my 20's, unmarried. It was a 3 year slog. Many employers will pay tuition if you are working full time. If you go the full time work/part time school route, suggest looking for a Master's program that does not...

    Connecting Skids Together

    mount nutplates (captive nuts) on the bottom sides of the top flanges. Then place a splice plate across the top, and bolt down thru the splice plate and flanges to the nutplates. or instead of nutplates, just weld the nuts to the underside of the flanges.

    Reverse Engineering Fabric Building

    I’m somewhat baffled why the OP would want a building permit for one of these shelters.

    Another Tarmac Fire

    “Since 1967 the NTSB has not produced a report increasing safety” this rubbish just proves how completely uninformed the idiot who wrote that article is.

    Load carrying capacity of 15x50 s beams?

    Is there a way to calc it? Maybe. Depends on the condition details and a lot of other stuff. Is anyone on here going to do it? No. Does the bridge currently have a load rating?

    Reverse Engineering Fabric Building

    but, but, it has "commercial grade" framing and fabric.

    Pump pad that straddles new and existing foundations

    huh? just change the piping. and frankly trying to save a bit of $ on the pad seems foolish re potential issues in the future.

    Pump pad that straddles new and existing foundations

    seems simple to rotate pump 90 degrees and solve the issue.

    Steel Beam size vs Wood

    why can't your engineer friend design a steel beam or channel doublers? maybe you need to pay him or another structural engineer.

    LVL Beam to Short

    the LVL is too short for a proper connection with the current hanger. epoxy filler will "fill the void" and have some minor effect but does not restore the connection strength. you need a much larger hanger or angles on each side bolted/nailed to the LVL and bolted/nailed to the ledger board.

    I need untreated 42CrMo4 steel S-N curve ASAP !

    i doubt you will find any S-N data, as almost everyone would use the steel in a heat treated form.
