What is that extension of broken cables that it was photographed above they hold down concrete area---- that cable looks like it unwound after it was cut and it did not fall down after that but only after other damage was done to itl little frog cannot be positive but I'm very suspicious.

The Way most universities work is they build up a couple of very strong departments with good well known faculty that gets grants--It is that department helps to bring fame to that university. The upper administration rewards and brags on those famous departments. Against this trend, the keepers of the Arecibo antenna went it to the University of Central Florida and a small weak, almost-department of astronomy. Nothing but a cooperative weak senior administration there would justify such an assignment. Not long after UCF became the custodian, the Arecibo big antenna fell down. The cover story is it rusted but if you look at the video of the hold-down parts-- you will only see exploding concrete around them-- not any rust. Little green frog wants to know IF Arecibo antenna was destroyed to stop its use for UFO communication? Having been a suffering faculty at UCF, frog is very suspicious.

Thank you!

hi can u also use STAAD?

Is there any resource for precast design for lifting handling transport demould ect

Thank-you for your video. Waffle pod internal slab with an (non-waffle pod) external concrete area that has an edge thickener and saw cut joint. So, like a patio but not step-down.

My notification bell will never be off for this channel 💯👌. Thank you Engineer. Look forward for more great info like this. 🤝🏾🇿🇲

Hi, does Intel Ultra 7 155H ok? (Instead of Ryzen 7 or intel core i7) 😃 I will start my class (Electrical Engineering) in few days and need the laptop tomorrow 🥲

"Australia 108" is Australia's tallest building at 100 floors, "Q1" only has 78 floors.

I disagree with your no. 10 precast can be made hollow core to allow for services to be ran through a structure.

What are the softwares u use

how about fire engineering? it seems this important factor was not being discussed

Excellant

Hello

your content is very good and the delivery is a bit too fast . the points are clear but they all seem run together as there is little if any pause between them .

Very interesting . i've been asking the following question for years and have yet to have a definitive answer . When i lived and worked in america it seemed as though all concrete cracked hence the saying " all concrete cracks " . Then i moved to germany where over a period of twenty five years i built two houses . NONE of the footings , slabs or walls have cracked yet . one house is about twenty years old and the current one is 8 years old . in both cases there is not the slightest of cracks hairline or otherwise . i am completely baffled . i don't know what the mix consists of but i do know the following - 1- slabs are eight to ten inches . walls are about eight inches . 2- rebar plus rebar mat is used and heavily supported . 3- the concrete is not ' finished . it is leveled and left very rough. 4- when hard , it seems to be much softer than what i was use to in America . a small hammer drill can pierce the concrete with much greater ease .

Excelente explicación introductoria a FEM

Good video, but slow down your delivery, you tend to mumble your words.

I'm a mechanical engineer and not a structural engineer, but I just bought this because there's always new things to learn🤩

Just on sustainability, could pre-caste not also be reused? Say you have an old building and it's demolished, couldn't the old bricks and concrete pieces be taken to a plant, broken down further and then reused as aggregate?

if they cast the anchors into the top of the tunnel they wouldn't have been a way for them to fail

Why are PRC precast homes almost impossible to be mortgage in the UK ?

Is math jot free for commercial use there is no paid plans?

I keep hearing so many different opinions on material. I've been told steel is more cost effective compared to wood from one company and architects say concrete and steel are expensive. But here I'm hearing it's not expensive?

Awesome content. 🎉 Also can you please do a video about comparison about wind load calculation based on American and European standards. Wind gust speeds, Mean Recurrence Interval etc on different standards confuses the engineers some times. Thanks 😊

10:37 In what units is the δ in that formula, mm I suppose right?

Topic of the video fits my PhD dissertation thesis: Experimental and numerical analysis of wind pressure coefficient. Cheers!

Thank you for the video. Could you please when you consider your next topic include the earthquake and diaphragm\ shear wall design as well?

4:28 - - wind in business districts 4:49 - - as a building gets taller - the wind load goes up vertically 5:10 - - wind must also be calculated for 40x the height + a 500 meter radius around a building.

Great content Brendan. Living in the Caribbean we have to design for hurricane categories from cat 1 to 5 with wind speeds at 74 to 157+ mph. We recently had a cat 4 passing between barbados and Tobago with effect from the outer bands. Thanks for the video Malik from Barbados.

That’s very interesting about shielding. ASCE 7 (for the US) explicitly prohibits any reduction in wind loads due to shielding unless a wind tunnel study is performed. Some of the reasonings are that 1) if the adjacent building gets demolished in the future, you wouldn’t be able to count on it anymore, and 2) reports have indicated wind regenerating or picking up speed around the corners of adjacent buildings. Just food for thought. Keep up the great work Brendan!

Currently, CFD can be utilized to obtain wind load for complex structures.

Sir do you earn 150k dollars a year in Australia now? Plz reply. Thanks a lot.

Hi Bredan, What's your opinion on placing polystyrene boards inside cantilevered canopy rc slab before pouring concrete to reduce selfweight of the slab and consequently reduce the likelihood of excessive deflection.

This channel is Gem.

What about empathy and intuition

I applaud you for bringing model error to the forefront in this basic way. It’s good to see another engineer do this. A survey I have done amongst engineers on the east coast of Australia has revealed a very startling pattern of poor modelling in FEA software. The misuse of ETABS and its legacy methods in particular.

I am a structural engineer here in Australia, have 20 years of experience. I have been using advanced non linear analysis for over 15 years, for seismic actions and wind loading. I’ve been developing new methods of engineering precast concrete structures using vertical post tensioning. We have undertaken physical full scale testing at Swinburne university on this new innovative system. I’ve used non linear pushover analysis for structures here for 12 years on very tall towers to sway frame retail structures. It is very true that PBD produces structural optimisation, even under wind loads. As a professional engineer the attacks I have been subject to during peer reviews by the biggest consultants in this country has been extraordinary, and depressing. The more advanced you are as an engineer, the more the code compliance specialists undermine the profession and innovation. I am quite impressed and happy you have produced this video. Reach out if you want to discuss.

@ 5: 47, It shows the side view of the rectangle support beam, it does not show the orientation of the rods as would be seen in an end view. Other drawings show the one piece all thread rods offset in the rectangle beam. As built and in the photos, the two-piece rods pass thru a hole in the seam weld in the center of the beam, it's weakest point.

Love you sir❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤ You are great

Hi sir I am from Basti Uttar Pradesh India I see your video it seems very informative as I am also graduate in civil engineering

What would you suggest for new commers because of artificial intelligence? Will structure Engineer be obsolete gradually due to ai & BIM softwares?

You can do civil engineering as well as structural engineering too. That's what I did for 45 years. I enjoyed a variety of projects and activities within those projects. I thoroughly enjoyed my career. Retired in 2016.

Interesting. I am 65 now and I qualified as a MIStructE in the uk when I was 28. I have lost count of what I have designed - from football stadia to airports to bascule bridges and I found my work so satisfying, especially in those early years. I started work in the early 1980’s, prior to BIM and when we ran our FE analysis over night on a main frame computer and had to check the outputs by hand using Kleinlogal diagrams.

very relevant topic, Thanks Brendan.

What if you bore or tunnel underground and build base underground which would help protect the base from external factors also maybe onion-type protective layer structures may work

With statement "There is a con in the name" you lost your neutrality 😂

Got my construction exam tomorrow. Your content is so helpful!

You could make a 'green battery' using one of the volcanic cones . Have a tram fitted with a dynamo and a number of electric car battery's on a track that spirals around the cone from top to bottom. Have the track slope in towards the cone . The decent can be controlled so it builds up some speed before the gearing / dynamo is enguaged via the load placed on the dynamo. Very near the bottom the resistance can be incressed to slow the trolly. Severial battery's the carriage and the dynamo would provide a lot of force. Just need the maths to know if its viabile. It would be cheap due to the site and parts, the location and proximity of workers. Close to the demand and educational, maybe even a tourists destination.
