Structural engineering can seem very complex, however, Structural Design is not as complex as your think. There is really only one structural mechanic that your need to keep in mind when designing a building. This structural principle is important for for all aspects of structural engineering from slabs to transfer structural and walls to columns even connection design.
This Simple structural principle is that loads flow to structures on stiffest parth first, balance deflections and you find your load parth. There are two way that a load parth can change first that parth breaks, and the second is that parths become softer as they support loads. To resist forces beams and slabs deflect, columns and walls shorter, even struct and tie actions flow through structures on this principle. loads is always trying to travel to equilibrium.

I love the explanation is simplified. Thank you, Brendan. Most informative and useful..
This was awesome Brendan! Load path is certainly something that I hear about all the time but have picked up little to no knowledge from school. Love the mechanics talk!
Hi Nicolas, understanding some of the simplified concepts can prove very useful. Thanks for watching.
Great video Brendan! I really enjoyed the 101 design mechanics. Continue with the good work and be safe out there.
Hi Malik, glad that you enjoyed the video. Stay safe and keep learning
Great video! Teachers need to be more like you, easy to understand
Glad it was helpful! Thanks for watching Lucas!
Thank you, Brendan. Most informative and useful.
Hi Paul, thanks for the support glad that you thought it was helpful.
Great video Brendad!!!
Thanks for the support Alan.
Nice video. A great tutorial for graduates and experienced engineers alike.
Hi Cornell, glad that you enjoyed it. Thanks for the support.

I always find two-way slabs interresting, because they are so many variants of it depending on the column grid layout and the preferences of the designer. In a local (rather large) underground parking garage I’ve come across different approaches with the use of column strips. In some area’s they’ve thickened the longest span, in other area’s the shortest span. I remember when it was built, they used both semi-precast slabs as well as hollowcore slabs with in-situ top layer supported by semi-precast column strips. In the case of the combination with hollowcores, the column strips are used on the shorter span. The garage is consists of two levels and three distinct sections, all built by different builders. Since there are building on top of it, the deck under the street level has really heavy transfer beams whereas the middle floor has the slabs with column strips.
Hi DYKO, all Slabs support on column behaviours in twoway actions even with beams, it is just a function of the beam. The stiffer the beam the more it will behave like a one way Slabs. Thanks for the support.
Great video Brendan! Extremely insightful - currently I’m a student here in Brisbane studying civil engineering however I’m tossing between design (ie WSP, Hatch etc) or pure construction companies to work for (Lendlease, Multiplex, CPB). However I have an appreciation for both - not really sure what the environment is for each of the above , similarities and differences. Whenever you get the time it would be great if you could do a video on this!
P.S. Keep up the great work with the awesome engineering videos :)
Hi Ammar thanks for watching. I have a video on small vs large compaines. WSP or hatch are a good choice. I will need to do a video on design vs construction compaines.
Your channel is an inspiration.
Thanks for the support and watching
Every object will try to reach its minimum potential energy and it will take the most straightforward route to achieve that minimum, that most straightforward route, in this instance, is the stiffest part (least deflection) once that starts to deflect it will "look" for another way.
True Adalsteinn, thanks for watching and the support.
good video, it helps a lots.
Hi Mandy, glad that it helps. Thanks for the support.
Sir you just made structural engineering so simple...Nice and simple explanations👌..Keep sharing your precious experience to us👍
Glad you liked it, thanks mate!
Awsome topic, very very fundamental one. Expecting more videos of such kind Brendan. Keep it up. I have shared it to some student groups too. Also how did you create that animation that shows the amount of loads taken by each column. Thanks
Hi Deepak, thanks for the support, sharing my content helps alot. The animation was a voronoi diagram generator. Tho tribby3d does it on column layouts.
Hello Brendan, Great video as usual, in the same topic direction can we have a brief explanation of the push over analysis and how is it applied practically, and what it its stand point regarding the building codes...
Hi Yassine, thanks for the support. I have a video on performance based design that covers some basics of push over analysis.
Thanks Brandon. God bless you. Please could you talk about the software that helped you approximate the tributary areas for each column.
Hi, thanks for watching. I will add it onto the list
@@BrendanHasty Thanks Brendon. You're the man 🙌🏿👍🏿
Hi Brendon, nice effort do more videos. Can you make one video about earthquake design of buildings.
Hi thanks for the support. I do have an older video on earthquake design. Tho it is time to make more.
the things they never teach ya in school. ur the man, Mr. Hasty !
Hi Sage, sometimes the simple thing arnt taught. Thanks for the support
Initial Qualitative Analysis/Assessment is the 'Fun' Creative Process 👍
Hai Brendan .. I have just began my career in structural engineering from India. I am trying to move to UK for a structural Eng .job.. But i am not confident in my knowledge of RCC design , also I am struggling to understand British Codes and Design ... Could you Recommend some Civil Engineering books based on british codes that completely teaches the RCC Analysis & design , based on British Standards so as to clear my basics first ..I would highly appreciate if let me know the books..
Great video Brenda! I like your content so much. I am a draftsman working in a civil and structural consultancy firm. I like to learn about Structure mechanics, do calculations, structural modeling, and have a very big passion for it. But how far I go but I am still a draftsman. Do you have suggestions so that I can have a bright further in this industry?
Hi Derick, if you want to stay in drafting, look into detailing and design mechanics. I good drafters have asked me many a good question leading to better designs. Producing drawing sometimes you will see something the engineer has missed. If wanting to move into design go for it, you many need to make it known to your current employer the skills that you have.
@@BrendanHasty Thanks 👍
Essential knowledge
Hi Julian, your support is greatly appreciated. And agree that it is essential knowledge.
Can you do a video to talk about flexible diaphragm and rigid diaphram, much appreciated.
Hi Andy likely incorporate it into a video for earthquake, thanks for the suggestion.
@@BrendanHasty that sounds awesome mate looking forward to it!
Hi Brandon! Linkedin working in your country?
Hi Bunbun it is working
Can you please do some examples?
Specially regarding demonstrating load paths by hand/FEA software?
Hi Rabib I doing a video on load parths, as for software I will need to see how I can do it with out costing $10k for a licence.
It is something in the planning.
Keen to see the load path video regardless.
Loads doesn’t cascade from stiffer elements to less stiff elements, it travels simultaneously along all possible pathways in proportion to stiffness.
Yes, load it transfers based.
but as parts get more loaded they deflect, this transfers they load to the part that hasn't deflected. So load spreades based on stiffness with the stiffest parted "becoming less stiff" delfexted the load distribution is proportion based on stiffness.
The basic design procedures
thanks for watching Diwitdhar.
👍🏻👍🏻👍🏻
Thanks for watching.
2:08 I presume this is why in nature, we tend to find far more curved things than straight things.
You can learn alot from nature and how structures behave.
@@BrendanHasty Math merely precisely describes natural phenomenon. Like all languages, math isn't an ends; rather, it's a means. Too many engineers become enamored with tools and processes, while losing focus on the fundamental principles. I've worked with many software engineers like that. They have driven me nuts!
I dont want any of my columns to be soft
I wish I could understand Australian.
"Load travels to the stiffest part first"? That's the "only thing you need to know"? That's plain wrong. Load travels to components in the proportion to their relative stiffnesses....
[Maybe you clarify that later - but once I heard that badly wrong Universal Truth, I didn't watch any further...]
Hi danguee load travel to their realive stiffness. As the load is applied to the stiffest element it becomes softer so that the relative deflections match to share deflections
