      I am personally going to trench my footings into my ground + form them on the surface with 2x4 for leveling / squaring ease. good luck. at this point it's more about doing than listening to internet how to videos.

      Absolutely me. I majored in Mechanical Engineering and want to build my own house. Problem is, I am scrutinizing every little detail before I even draw plans. Maybe after 20 years I will get it done :) In a serious matter, you cut one wire, and we don't have water, heat, much light, or even an outhouse. I can live with it a week or so, but how about years??? People do not realize just how INCREDIBLY DEPENDENT we are on the normal functioning of society. I don't want to live that way. Second, I believe the Bible, and I believe it prophesies that the worst is yet to come and soon. Another aspect is this prophecy: "there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great... and the cities of the nations fell... and every island fled away, and the mountains were not found. And there fell upon men a great hail out of heaven, every stone about the weight of a talent (75 lbs)" - Revelation 16:18-20. In other words, every skyscraper is coming down, and at least some, if not all, mobile homes being cannoned from above. I just don't know if I can, or if I should even try to, build to that standard. Maybe I shouldn't try for a 1000 year house life, but just a 16 year or 63 year - whenever the events happen.

    More great content! Thanks Brendan! For the past two years I've worked as a site engineer, however, I never had as much passion for it as I did for the structural engineering I did at uni. I've recently made the decision to change the direction of my career and pursue work as a structural design engineer and I've been using your videos to re-educate myself on some of the stuff I learnt in uni.
    Unfortunately, finding work has proven to be rather difficult, as I'm also new to Melbourne and don't have many connections here. With two years of experience in the industry as a site engineer having lots of practical experience with structures, I really though that getting a grad position as a structural engineer would far easier than it's proven to be. Regardless, I'm still driven to continue down this path and your videos have certainly kept my motivations high, so thankyou for that.
    Would you have any advice for someone in my position?

    Good work. As an architect and teacher with an emphasis in structural engineering, I would have enjoyed this comprehensive overview when starting out. The only thing I'd change is (and I'd definitely change it), instead of rushing into detail (a fundamental pedagogical error) I'd speak more broadly in a longer overview, generalizing about foundation and footing types, then about soil types before going into detail. I'd also slow down the edits. Brains need time to breathe while taking in information, especially in dense. Cheers,

    Great stuff! Would you be able to comment on the load combination used to determine pad size or checking if the soil capacity has been exceeded? The book Concrete Structures says it should be the unfactored load combination, which is consistent with the practice used in many other countries, but this is not mentioned anywhere in AS1170.0. A bit uncertain of the engineering practice in Oz. Thank you in advance!

    • @BrendanHasty
      @BrendanHasty  2 роки тому

      Hi Deyu, this is something that can be discussed with the geotechnical engineer. as bearing capacity is governed by settlement, it is typically based on a services load so G+LLR. but it is best to conform with the geotechincal engineer. hope it helps Cheeers Mate.

    hello Brendan,
    what it happens if the steel bars are distributed ununiformly in compression and tension zone due to poor workmanship, would it lead to cause additional flextural moments and torsion, and shear stresses, could we solve this problem by using carbon fiber strips, or what are the other suggestions to solve this kind of problem ? thanks in advance

    • @BrendanHasty
      @BrendanHasty  2 роки тому +1

      Hi Rawaan, strengthen using carbon fibre is limited as it is non-ductile, 10 to 30 maximum additional capacity. Still lots of assessments to prove it up. If really bad may need to remove the concrete using high pressure water, replace the reinforcement and resources.
