How much is each steel bar by meter length? Once the steel bar are installed and bolted can hard wood be used rather than hard concret blocks?

When I first saw this video I was suspicious....A 'professional' giving forth this info? But having watched it through, I am impressed. Well done! I am 75 years old, still practicing: P.Eng, MiMechE. MiStructE.. With half a century in Structural engineering. most of it in Offshore O. and G. particularly with steelwork, from mudmats on the seabed to flarebooms at the highest point, and all the areas in between. The last 15 years being involved in design analyses and engineering for drilling facilities, typically with 2 or three support modules weighing up to 4000t. My work has included being Lead Structural Engineer(drilling) on the biggest in the world, (so far). I loved it all and I am still at it. Respectfully, listening to this young man, It is so good to see the future of our discipline is in good hands.

[@stephenbrickwood1602]

A shitty cadetship, a few recessions, no mentoring, but I still managed a full Civil Engineering Degree from UNSW. The details you talk about is exactly what I missed out on. I ended up managing civil structural construction and building projects. My engineering insights allowed me to make many critical decisions over the years that saved the client $millions. I have had a lot of 'adventures' in these roles and worked over seas and met some brilliant people. I have never structurally designed anything sadly, but I have seen some very dangerous designs by foolish and ignorant amateurs who were lucky I questioned their work. I am in my 70s now and appreciate your presentation and the mentoring it provides.

[@BrendanHasty]

Hi Stephen, thanks for your support. Alot of designer ignore the construction side, your experience would be invaluable. Despite not designing any buildings your input made them.

[@stephenbrickwood1602]

@@BrendanHasty From the prebuilding side of the problem I have had a few projects redesigned and saved significant costs. My disappointment was that the financial bonuses at the end of the projects were often ignored. I did have 'mentoring' from 'hard nosed' construction managers who's detailed focus showed the benefit of hard work and the type of skill needed in the construction phase. Engineers are not good at self promotion but they are the ones 'sticking their necks out'. Sadly many of the 'good self promoters' were the dishonest shonks. Thank you for the chat.

I did not think that this person actually existed. An engineer that takes into consideration the fabricator and erector. After detailing and fixing the EOR's design for twenty years this is very refreshing.

[@BrendanHasty]

Hi Andy, Thanks for the support. I think every design, well, at least a good design, should consider fabrication and erection. Building is hard enough to build without doing this. If it is easier to build, it will be a better building. I actually recommend that early on in the career of an engineer, they work on-site for a year or so; this gives them great feedback on their designs and how they can make it easier to build. but agree a lot of engineers do not, think that it is someone else's problem

Hi! Great video! About galvanic corrosion, the usual thing that happens in the project (esp. loosely coordinated ones, at least here in ID) is that another contractor came in without knowing what galvanic corrosion means, and starts welding stuff. Saw it once during my whole career (which isn't that long). It's really rare though. Most people here install the facade on the concrete surface covering the steel so everything should be safe. Also, should be noted for the international audience, that the rule of thumb works with the specification of mild steel where you're at. Chinese steel have slightly different standard.

Excellent. Galvanic reaction also severe when using Stainless Steel fasteners on steel, galvanized steel or aluminium.

This is very positive! I used to erect a lot of steel structures in a previous life as a rigger and crane driver and I can remember being so frustrated at the stupid design engineers who didn't think of how someone was supposed to physically put a bolt into a connection!! I'm so glad you're actually thinking about this basic detail!! I remember finding out that engineers in Germany had to do a years work on various projects as trades assistants before the could finally gain their full qualification and they seemed to turn out the best engineers in the world! No substitute for some real world experience!!

[@BrendanHasty]

Hi Jono, thanks for the support, Good design requires engineering to know how the building will be built and the limitations that will be on site. I agree that all structural engineers should spend a year or so on-site to know the issues that will occur on-site. It makes you a much better engineer and will lead to better designs and better buildings.

22:26 Opposite. Aluminium alloys are less noble than steel*, the aluminium will become the anode and corrode**, not the other way around. * Despite being more reactive, aluminium corrodes in alkaline environments, and, in general, the environment is rather acidic. Steel corrodes faster in an acidic environment, so in the end steel is more corrosive - but this is because of typical environmental characteristics rather than the material itself. ** Providing the volume of the anode is equal to or smaller than the cathode.

Dull topic, but interesting as a back yard engineer :-) One tip: if you cock up the audio in your original recording and do a rerecording of the audio only then at least do it with the same mic at the same level in the same acoustic environment so that when you splice it back in the audio is seamless and the only risk is the cognitive dissonance of the lips not matching the sound. You did this once in the middle and recorded the replacement clip on a cell phone or something.

Hi Fredio, thanks for the support. I do try to do that; it is using the same audio equipment, external recorder, same mic and same room; maybe I need to set everything up again.

[@rckygrhm1]

Hello from Perth, The video is great; if you ever get time, please consider some simple worked examples from the Steel designers handbook, to show steel sizing calculations. Maybe can do some Spacegass steel sizing examples for simple structures. Do you use much excel spreadsheets for steel calculations?. I try to use all three of these and am wondering your methodology . Also, how do you document the finished steelwork; for example Spacegass reports? do you use the built in report generator? or document each beam seperately etc.

[@BrendanHasty]

Typically I use Excel or mathcad to design simple structures. When modelling in spacegass I use the rule keep it simple KISS, complexity complicates checking the design. And typically I build up the complexity of the model simple to more complex in stages if a complex model is required. Will likely make a video on my work flow.

Hi Guy， thanks for your support. and total agree with reviewing past failures to ensure you learn from them. Good design should be always the number one goal.

How can I prevent cracks in partition walls due to deflected structural beams' interaction?

[@imran7075]

Brilliant Brendan . A lecture on gravity based onshore wind turbine foundations would be great...

[@BrendanHasty]

Hi Imran, thanks for the support and suggestion.

[@epistte]

I had a temp job in college doing steel detailing. I wish I would have known this then instead of learning on the job.

[@BrendanHasty]

Hi Epistte, agree learning on the job cam be time consuming, wish I had posted this early to help you out sooner.

[@epistte]

@@BrendanHasty The temp job was in 1989. I'm old. Obviously pre-internet and pre-CAD. Everything was on vellum.

I wish steel wasn't so expensive

[@BrendanHasty]

Hi Kelly, I Agree. Steel prices have gone up way too much recently. This is due to the government spending so much on infrastructure all construction materials have risen in cost. I hope they lower soon; I love designing steel structures.

[@DriesRoelandt]

Really good video, everything was explained very clearly. The music was sometimes a little too loud but that's just my personal opinion.

[@BrendanHasty]

Hi Dries, thanks for the support, Aggree that sometime the music may have been too loud. always looking on making the audio better, thanks for lettting me know.

Hi Brenden, I am loving your contents. Will you please make videos on Seismic Zones and Ground motion parameters.

[@BrendanHasty]

Thank you for your suggestion! I have put it into my planned video topics.

[@PeterRanieriII]

What would you classify a composite steel and deck with say 6" of cast in place concrete for the floor structure's diaphragm to be: rigid, psuedo-rigid, semi-rigid? Would you transfer lateral forces 100% through the floor system to the cores/braces/moment connections? center of mass and center of rigidity are close to eachother. Thanks

[@BrendanHasty]

Hi Peter Typically, I model it as semi-rigid. Computers are powerful enough nowadays to model them as semi-rigid. The lateral forces transfer through the floor system to all the stability support. Center of mass is just a simplification; when COM and COR(Center of Rigidity) are close, there isn't much torsion.

[@PeterRanieriII]

@@BrendanHasty got it thanks for the response. Yea I like the way the lateral system reacts when modeled as semi rigid as it seems to be a more accurate representation of what occurs in real life I would think. I have another question: when I design a steel building I like using as deep a beam as I’m allowed not only for its cost of efficiency but I find that the couple created at the column connection is greater even though we say the connection is simple and moment is not transferred to the column via the beam flange, in reality dont we have a small amount of moment going into all the columns when the diaphragm moves?

[@peeolo]

@@BrendanHasty i do the same, but it's comforting to know that others do so too. very often in europe colleagues concentrate on calculating the beams, neglecting the connections and above all dedicating very little time to shop drawings and feasibility. for steel I think it is essential to know the processes in the workshop, the different tools they can use, how much space an operator needs to screw a bolt or to weld two sheets of metal, hanging in the air at a height of 8m maybe

[@jordzzzzzzz]

@@peeolo Thank you for thinking about how the welder is gunna be able to weld that. The struggle is real sometimes… As a structural Ironworker one thing I notice that is missed quite often is deck support around columns.

[@peeolo]

@@jordzzzzzzz i was a bricklayer and truck mechanic before to become an engineer. People Need to work with my drawings. They're not piece of art or "some pretty nice sheet of paper". Thery are fabbrication drawing....for fabbrication not for art

[@dannmwangi5235]

Is there any specific angle for constructing a steel roof?

[@BrendanHasty]

Hi Dann there is not specific angle, but there is a mimimum and it is based on the roof sheeting. typically a minimum of 3 degrees but be carefully of deflections as this reduces the pitch.

[@baburamabadhran1437]

Also for wind load during cyclones what is criticL. Is it the panel steel sheet thickness so they don't fly off. Also structural rigidity to stay in place and withstand wind loading what is the key precaution.can you pl tell??

[@BrendanHasty]

there are addition requirements in Cyclone zone, you also need to design the cladding for impact loads

[@baburamabadhran1437]

@@BrendanHasty thks. But I meant wind loads . And where does the impact load steps in. Sorry if I am wrong.

[@MsDJ619]

Great video, would liked more photos and videos shown to explain what you are saying, i had some difficulty to understand some things you said, perhaps that's because i am junior ^^

[@BrendanHasty]

Hi Brooks thanks for the suggestion, i will look into improving. Also, maybe i was talking too fast. hope to impress is my future videos.
