    box culvert analysys

    PD 6694-1:2011 is a Eurocode document specifically about the design of buried concrete structures. 10m is unlikely to be feasible but multiple units would be.

    Steel Cranked Beam End Supports

    I don't see much of an issue with that.

    Residential Load Bearing Wall Removal (A basic task & possibly an ignorant question.)

    What we call 'buildability' - can the beam be physically installed? Does it need splices? How will the opening be propped? Will propping interfere? Are there significant services that need to be removed? You don't need the full answer to this, but some thought and warning to the Contractor...

    Crazy cantilevered steel deck

    It's a reference to a meme where hot tubs have been put on some very questionable locations.

    Pin in Shear vs Bolt in Shear - why the difference?

    Is it to do with bolts being part of a system of bolts, whereas a pin is expected to be a single pin?

    Crazy cantilevered steel deck

    What about when they add a hot tub?? I did think that but then the house is sat on the rest of that pad.

    Is clearance needed at the 2nd-floor columns

    No I wouldn't expect blockouts in that situation. The slab on grade has different support and foundation conditions to the steel column, the upper floors are essentially all the same structure.

    Help Designing Masonry Wall under Vertical load and Horizontal Point loads

    My gut says that won't work as a unreinforced masonry wall

    Ladder Safety Systems

    We're not talking about design, though, we're talking about assessment. We can make assumptions about the construction of the ladder but unless we have the original specification the assessment is going to be based, at some level, on assumption. Anyway, I was only proposing it as an alternative...

    Ladder Safety Systems

    Conducting a test is applying engineering knowledge. I just think when you're getting into the realms of FEA on a ladder, rigging up a test could be time better spent... Any code of practise or safety regulation I'm familiar with allows testing as a means to demonstrate suitability.

    Ladder Safety Systems

    If there's a lot of ladders then it could be economic to undertake load testing on the actual ladders/fall arrest system in question. If it snaps like a twig then the Client has a very visceral sense of why it's not acceptable.

    Composite Metal Deck (Fastening)

    If there are welded studs then the fasteners aren't needed. However there are some advantages to fix the deck in place for construction and safety reasons - but that would fall to the Contractor to consider and decide on, and shouldn't make any structural difference given the eventual presence...

    Reinforce masonry wall to deal with settlement risk

    I should dig down adjacent and get a soil strength test done. Then you can make an informed decision over what any likely settlement would be. With a single story building and a metre wide reinforced footing, I would not be very concerned. Sliding starter ties to the existing building and proper...

    Min reinforcement steel in foundation for self erecting crane

    You could make the argument in this case. The OP says it's a raft, so assuming there isn't full support from the ground and the raft does need to span, then minimum steel requirements has relevance. - But is ensuring ductility a significant concern? While it's preferable to a brittle failure...

    Cover your pergola

    i should think the plastic sheet fails before the frame or the house!

    Structural Ridge Beam Force direction

    Load will go where it is stiffest. The vertical supports for the ridge beam are likely to be the stiffest part so i would expect the load to transfer via the ridge beam to the vertical end supports. However I'm not sure how your intersecting sloped LVLs will 'lock everything together' but I...

    Fasteners for wood lath and plaster ceiling

    Early 1900 would be iron nails so they're as likely to have rotted through after 110 years. Can you not inspect the nails and/or the hole they came from? I assume you mean the modern code requirement but I don't believe there would be one for lath and plaster. Here we'd replace with...

    Brick Arching Action

    I had drafted a longish reply but the save draft function hasn't worked! In short - yes arching action in the wall above is reasonable. If the joists are in good condition and mortared in then they shouldn't necessarily affect that, but prudent to allow for it. The load from the floor would be...

    Strap bracing for roof purlin

    I think 'strut' is just a historical term rather than any literal compression meaning. https://www.screwfix.com/p/simpson-strong-tie-herringbone-joist-struts-480mm-25-pack/765TJ Getting the right tension might be a challenge using rolls of strapping.

    Strap bracing for roof purlin

    I'd call that a herringbone strut, sometimes seen in timber floors (although a bit old fashioned now, still available to buy).
