I am a graduate Structural Engineer and have started work experience with small firms who doesn't provide any training and I need extra support ... I wonder if there’s any possible for help

Please use a software for beam design and can you recommend sizes for houses developments and crank beam designs for loft ?
I loooved this video. My final year project entails the design of a 3 storey office block and this gave me a head start on how to approach the problem. Thank you so much!!! You're a life saver
THIS IS PURELY A GIFT FROM YOUR FOR ALL CIVIL ENGINEERS, THIS HELP THEM TO GET BASIC UNDERSTANDING OF THE STRUCTURE AND MAKE CALCULATIONS EASIER FOR THEM . I REWATCHED IT MANY TIMES, I HAVE TO APPRECIATE YOUR EFFORT BEHIND THIS VIDEO, IT MUST HAVE TAKEN A LOT OF HARD WORK, PRECISION AND CARE TO PRODUCE SUCH HIGH QUALITY CONTENT
Hi Everyday Dazz. I'm a huge fan of your channel and the information you've share. I'm a Structural Engineering Student from South Africa, and I'd like to grow professional profile by taking on personal projects and i'd like to focus on residential homes. I have had some experience in designing of structures, but not enough of me to get a full understanding of load take-down if a double story residential home, especially if I'm determining load take-down using an architectural house plan. Could you make a video of such an example in the future if you have any examples and approaches you are able to share? I think this would greatly broaden our understanding, and give us the confidence we would need to take on bigger projects as graduates. Thanks
Can I just say, as a newly graduated engineer, your channel is a god send! Thank you for the helpful vids ✨
I have been having trouble with load carrydown. Thank you sir
Lovely explanation... Easy to understand 👌👌👌
Hey, Engr. Superb content! Would love to see more of conceptual and manual calcs in actual practice! Thanks!
Agreed
Amazing work Dazz. I watched this video and constructed my own spreadsheet. I would really like to know how you calculated the foundation, raft, and reinforcement using the real-life example.
Thanks for the comment. Raft design is something I’ll do at some point for sure 👌
Great video, Dazz. Thanks for sharing.
Pwoli....well explained nd great👌👌👌
Wonderful explanation. Thank you
Hello Dazz million time thxx for the videos... learnt alot from u. I have a question about trib area on 7.52 min ( 4.75m. Why not 4.75 m^2) could u explain. Cheers
Hey mate really good video! I’m in Australia and finishing up my degree in engineering next year. Just wondering if you’ve done a video / would consider doing a video on how to make the spreadsheets for design. Cheers mate
Thanks 🙂 yeah can definitely add it to the list of videos to make if it’s something people will find useful 👌
can you do a video on how to size beams and supports using the calculated loads?
Thanks for this video!
Could you do a load bearing takedown of a solid slab
Magnificent video
This is so helpful thank you! Could you do a video on how to do a load takedown spreadsheet?
Can add it to the list 🙂👍
@@EverydayDazz waiting for it now...
please
Thank you so much
Thank you very much. I wish to know if it is necessary to take live load reductions into account ?
I would only really consider for taller buildings
you have made a small mistake mate, you put 0.006 x 22 = 1.65Kn/m^2 it should be 0.075 x 22= 1.65Kn/m^2 great video keep up the work can you please do a video on wind load calculation inaccordacne to eurcodes.
Thats not his only mistakes - he commented on all except yours. Hes a fraud.
@@Userxyz-z2d I wouldn’t go far to call him a fraud. It was a honest mistake which he has not rectified, I only wonder why.
Amazing!
I am confused on one thing, when he did the Area load for the Timber joists, the 2.5 for the number of joists, how is this m/m2 ??? This is important to get the final answer in kN/m2 but I can't seem to see how 1000/400 is m/m2? Thanks,
Great content, could you do a load run down for a corner column and show how you determine moments about both axis?
Thanks for the comment, I'll bear that in mind. Determining columns by hand isn't something I'd normally do. In short, you'd do a 2D frame analysis in both directions. Generally, I try and scheme a building so that the stability system is not dependant on column stiffness so either I've using bracing or stability cores. Therefore eliminating the need to design the columns for additional frame moments.
@@EverydayDazz thank you for the reply. Just coming into semester 2 of my masters and that was an area that gave our group the most grief. Great videos, look forward to more
If you are still having trouble. I suggest this technical guidance from the iStructe. Just google 'iStructe L2-5' and one of the first things that comes up is how to design concrete columns. It should be a free download if you become a student member with the iStructe. iStructe has loads of these technical guidance notes which should help you out in a range of different designs.
@@EverydayDazz exactly, very practical thing to do
Hey, I'm going into 3rd yr of Structural Engineering, I really want to get the structural engineers pocket book but have seen reviews that there are errors throughout the book, have you had problems with it at all? Just found your channel, cant wait to watch all your other videos, it's great to see a structural engineer on youtube who uses Eurocodes too 😊
There are some errors but not many it is still worth getting in my opinion
@@EverydayDazz I have both the euro code red book 3rd edition from 2013 and the British standard 2nd edition from 2017.do you know why the 2nd edition came out later than the 3rd edition also which one is better to use? The 2nd edition is a smaller book but there doesn't seem to be much difference in the info within them.
im curious. for the deadload do we not need to count beam and column self weight ?
You do but generally it is small in comparison to the other loads. But yes technically you should factor it in
Is there a red book, but for USA codes
Lets say your soil bearing capacity is like 75kpa and you calculated the line load in kn/m. How do you do the calculation to know if it is satisfactory?
you then need to design the foundation width so that the pressure exerted on the ground is less than 75kpa. i've done another video on it th-cam.com/video/MfB_8uw08m0/w-d-xo.html
Could you explain why when calculating the Trib area you divide 5.5/2, where is the two coming from?
The Trib area is the area above the supporting member that is the source of the load on the member. Dazz didn't really explain (or labour) the point that he was calculating load on along a line of foundation that he had called "B". This shown in the video at 7:12. The source of the load on this foundation is all the wall loads plus half the floor loads between A and B, and half the floor loads between B and C (plus the roof loads similarly split). The other halves of the floor loads are carried on foundations A and on C, so the load on B is only half. He also didn't labour the point that to work out what load takedown calculations you need to perform, you first need to understand the building's structure so you know what load paths exists. Sketching the load bearing walls in plan and elevation is likely to help ensure you don't miss anything.
Kindly share how to draw this excel sheet and techniques to work efficiently
Bro am master studen structural eng so what kind books i need to refer when i makng design sturcture
I recommend structural design of elements by Chanakya Arya. It can be found on amazon. It can be a good introduction to design of the four main materials.
Bro, Idk if there's is really common there, but could you do the same topics but for a masonry building.
That was sort of a masonry building example.
I have a piled ground beam design coming up soon that’s going to be supporting a masonry building.
Have you ever had your calcs rejected by building control or even queried/commented on? In my 5 years of experience of submitting them to approved inspectors i have never heard a beep. Makes me wonder if they even look at them..
never had a rejection, just comments, mainly on very large projects and these just needed some clarifications.
I would say they do look at them but not with a fine toothcomb. If they understand the principles of what you are trying to achieve by a well explained calculation pack, then they have no reason really to reject it.
👍🏻
Thank you very much .. that is really helpful I wish I knew that earlier I could have progress futher .... is there any possibility of getting in touch with you for further information ... Please let me know ....
Kind regards

Thanks. If you click into my channel and go to about, there are my details
Is there a Software to calculate Building Loads? Since nobody in Europe pays you the time spent calculating this by hand
Of course but who inputs the data into software? If you don’t learn how to do it by hand how do you know the software is correct?
@@EverydayDazz yeah your totally right
please get with it this is America.WE use pounds,feet, inches. Metrics are a pain in the butt
The rest of the world uses metric and I’m in the UK.
