Dear Sir I am a mechanical engineer in the USA and have done a lot of machine design work. I am now designing my retirement home in Florida and I ran across your video. This video is absolutely fantastic ! I really appreciate the practical reasoning you use to explain and make very clear how to calculate the forces. Your students are indeed lucky to have you ! Thank you so much and please continue to make such videos.
I really hope your students realize how lucky they are to have you as their teacher.
It was crystal clear and super helpful.
Thanks a lot 🙏.
Thank you for your support. Glad it was helpful!
Again, I have to say this. This explanation is insanely clear as distilled water. Your students are so fortunate for having you. I wish that there was UA-cam channel in my University years. Bravo doctor. 👏👏👏👏👏
Hello Dr El-Gamel. Thank you for your tutorials. You are more than a teacher. Your elaboration is clear and hopeful every one can understand instead of creaming. Continue to provide other videos for the design of other structural members. May God give you a long life with Good Ends. Thank you.
Great explanations throughout. Thank you!
Thank you doctor for your kind act to help us,be blessed.
Thank you Doc. Your channel has been of great help.
Bravo doctor! Your elaboration is clear AND every one can understand!
Thanks a lot.
Very nicely described and taught. Thank you.
Regards
Thank you so much Dr. El-Gamal for the interesting video, I really understand the Foundations. keep teaching us more
Thanks really I appreciate your effort to make everything clear and God bless you
Very good explanation. Thank you very much.
Great explanation Dr El Gamal . thank you .
جزاك الله خير الجزاء على هذا الشرح الرائع و المفصل و أتمنى عليك يا دكتور أن تتحفنا بشرح مفصل لكيفية تصميم البلاطات الفلات و الأعمدة النحيفة و القواعد المشتركة.
Really helpful and very detailed , thank u sir
Thank you for sharing. Good job
Its really amazing, everything is well defined and explained.
Expecting more like this video.
best video regarding footings Design.Many Thanx Dr Sharif
Thank you Dr. Sheriff
You are the best in Civil Engineering
Thnks doctor , great explanation keep it up
Thank you so much for this video. Your have thought me what my lecturers refused to teach me in university. You have done a great job sir. May God continue to increase you in knowledge. Please I want more video from Raft and pile foundation. Thanks in a big time sir. May God bless you abundantly.
What school did u attend bro 😀😀
thank you so much for great content doctor if you have time we will be glad to watch video which you design some footing and foundation in real time
very nice lecture sir :) thank you very much
Thank you so much for this
Very nice lecture thanks alot sir.
thanks Dr it was a simple and useful video
You're a legend man.
Thank You Doctor
جزاكم اللّٰه خيرا كثيرا يا دكتور
Too good man👍👍
amazing explanation
Love this tutorial. Great explanation!!
Well explained.
Excellent presentation sir.simple and understanding.
Glad you liked it. If you like it, share it with your colleagues.
Thank you so much
Thank you for the video good info. When you record audio set input on mix -6db this will leave you enough head room as not to clip.
Great explanation. thank your your video
You're welcome.
Thanks our Dr. El-Gamel for this lecture.
Can you make a lectures for design a neighbour footing when the position of column at mid and other type at corner
VERY GOOD VIDEO TRAINING,
Thank you very much sir
شكرا لحضرتك جزاك الله خير
و انت كذلك. شكرا على الدعم.
Thanks doctor very interesting and helpful video from mauritius,
can you do some videos on Design of Retaining Walls to British Standards
شكرا جزيلا يا دكتور على الشرح والمجهود الرائع .. هل ممكن حضرتك تشاركنا بال PDF فايل بتاع المحاضرة علشان يكون سهل للرجوع له فى اى وقت... جزاك الله كل خير
Thank you so much Dr. Shareef.

Thanks so much Dr.
So nice of you
You are much more good to be a lectural. I appreciate your lecture.
So nice of you. You can help by like and share to transfer the knowledge
thank you very much professor i would ask you about the design shear for concrete how can I calculate its ?
Very very thanks Sir.
Most welcome

جزاك الله خير ,الفيديو افادني
Thank you for your interest. If you like it, share with your colleagues.
ان شاء الله@@MrElgamal77
Hi sir. Many thanks for the instructive video however i have a question. Should we backfill the footing? As i am thinking to make a basement slab just above the footer?
Very Good sir,
Dr. Sherif Thank you and I would like to ask you to add us staircase lessons in the you tube 👍👍
Please make a video on designing piles and applying spring constant along the depth of piles. Thanks
Love from BD.
Thank you sir this was very clear. Do you by anything have any lesson on long/slender columns as per BS8110
Thanks For Teaching Sir
It's my pleasure. Share with your colleagues.
الله يجزيك خير يا دكتور
Could you please upload a lecture for Liquid retaining structure design to EC2 or BS8110/BS8007
Thank you so much for explaining this. Could you upload a video on theory, analysis and design of staircase?
Love from Nepal
I will try.
Great explanation as usual! but how do you find the effective depth? do you simply assume the number and calculate based on that? or is there a specific method to be used?
If you're referring to "d" then I believe it's the distance from the top of the foundation to the center of the bottom reinforcement, if I'm not mistaken.
Thx sir❤
Thank you very much! Could you please upload a lecture for Liquid retaining structure design to EC2. Appreciate very much there is no guidance anywhere. Please!!
Also you are most welcome to Tanzania.
Fantastic
You are welcome
nice
Sir while designing footing, we satisfy only shear failure criteria soil or both shear and settlement criteria?? Plzzz rpy sir🙏🙏
🎉nice
Hello Dr El-Gamal. May i know the formula for calculating Maximum Bending Moment and Shear Force for a strip footing
Sir assalamualaikum i ask you if column jalli not centre of column because is less space. now what i do i design of uniaxel loading or not please your comments.
Thanks
😊
Sir which bearing capacity is used in design of footing??
Example: Safe bearing capacity or allowable bearing pressure
Romanian foundation design code for isolated footings is simple: To assume a linear distribution of the pressures, you need to ensure proper rigidity of the pad footing. This can be provided by respecting some prescribed ratios between H/D>=0.3 (Height of pad, D- bigger footing length). If not provided, you have to check one-way and two-way shear. Otherwise, it is just a recommendation.
Bravo
Happy to help
او شرح عن كيفية تصميم القواعد اللبشة بواسطة الكود البريطاني B.S بحيث يكون تصميمها as flat slab
جزاك الله خيرا دكتورنا وربنا يجعله في ميزان حسناتك بما تنشره في مجال الهندسة المدنية، بعد إذنك دكتور هل ممكن تعمل فيديو يشرح كيفية تصميم البلاطة الفطرية flat slab بواسطة الكود البريطاني B.S ولك فائق إحترامي وتقديري ..
ان شاء الله الدكتور يشرح الكثير ليسى هو في البداية..انت وين بتدرس ؟ هل بتدرسوا في الكود البريطاني؟
@@heshamalshammari5393
تمام ربنا يبارك فيه الدكتور ع شرحه المتميز ..
انا من اليمن وادرس ع الكود البريطاني
بس مشكلتنا في اليمن ما يعطوك المهنج كامل روؤس اقلام وما يتوسعو بالمهنج المقرر ومها أوضاع الحروب والأزمات الحاصلة يطر الطالب أو المهندس يبحث ويجتهد بنفسه ..
@@mazenabdu5205 حياك طيب باي جامعة انا من اليمن أدرس في السودان سنة رابعة..انا جالس انشر للدكتور على صفحتي على الفيس حتى يستفيد الطلاب الاخرين

Thank you so much for this Dr El-Gamal.
One question regarding shear stress; if it exceeds the concrete shear capacity, you mentioned that the solution is increase the height (H) of the foundation. Isn't another possible solution to use shear reinforcement?
Yes you can but it is easier to increase the thickness
@@MrElgamal77 I see. Thank you for your quick reply and fantastic work on your videos - really helpful and well explained. Keep them coming 🙏🏼
can you please a video about retainng wall
Remain blessed sir 🙏🏾
Thanks.
The most important thing is to keep the most important thing, the most important thing, and that is the "foundation"
Thanks for your fantastic videos Dr. 🎉 Assuming that the 40xbar diameter anchorage length is still too much length for the space available in a section, even after bending up the bar at 90°, what is to be done? Every other thing is well satisfied in yhe the section, just this anchorage length 40xd issue
Thank you for your nice words. You will never have such thing. You will need bigger bar diameters in bigger footings and therefore you will have more distance for the development length.
Hi, thank you very much for this nice video. I have a small question,
Why do we take SLS loadings (and not ULS) to calculate footing size?
Thanks.
Thanks for your interest. The footing area depends on the allowable bearing strength which is a SLS not an ULS. Therefore we use the service load not the ultimate.
@@MrElgamal77 Thank you Dr.
Thaks dr sharif
I wanna to ask you a quastion
Transverse shear stress or direct shear stress < 2VC shear capacity of the section of footing
That compare V
Thank u Sir. Can i get the ppt power point.
السلام عليكم
بعد اذنك اذا مطلوب نصمم shallow foundation والمعطيات Df وIDP و IDM وp و M مع fs=3 كيف اصمم؟
can i give me a sample of footing design
this is it.
Thank you. If you like it, share it with your colleagues.
thank you DR.Jazakalah please may you send me the ppt or pdf
is okay we will try to revise.
دكتور جزاك الله خير الجزا على الشرح الجميل لو تكرمت من وين اقدر احصل تفاصيل تسليح القواعد ف الكود البريطاني فيما يتعلق ان التسليح السفلي للقواعد يكون في الاتجاه الاطول من القاعدة والتسليح العلوي في الاتجاة الاقصر ؟ وماهي المشاكل المترتبة اذا عكسنا
Sir if have link please send,, how to check stability by eccentricity in half area footing,, like in boundry walll
Sorry, I do not have it.
are you using Eurocode 2 designing the fondation?
No. I am using the BS8110.
Why don't we provide steel reinforcement for shear ?
How is the moment calculated ? for the second case
What do you mean with the second case?
This is from IBC?
Dr. El-Gamel, is it correct to say that Gross Soil Pressure should be lower than the allowable soil bearing capacity? Gross Soil Pressure = (Column load including its dead load + Weight of soil above the footing + weight of concrete footing) / area of footing. Anyone ?
Yes
