DR Sharif I appreciate and thankful for wide wide explanation, useful and full detail of theory this lecture of one-way solid slab I pray to ALLAH bless your knowledge.
This is a masterpiece approach by a seasoned lecturer. You've done justice to this aspect of design. Please give more on the planned series. Bravo Zulu Dr. El-Gamal!
Thank u Dr Sherif Gamal,for the given lactur notes b/c it is clear and neat. but i would like you to give vedio notes on shear wall openings and their effects accordingly if possible .tkank u.
first of all thanks for Ur videos ,they are really helpful and appreciated. I was wondering if you could do videos on "Design of RC" according to EUROCODE 2.
I have learned alot from this professor mashallah may Allah give you alot more wisdom and give you Thawab inshallah thank you so much........... I watched beams slabs column and foundation. please can you also do stairs?
He'll Engineer, once again, thank you for your tutorials. I have a concern, while calculating the depth of a solid, we multiply the basic ratio by a modification but the case is not the same while obtaining the depth of a beam. Kindly explain the difference. Thank you
Also wondering the same, where did the equation {effective depth = span/(basic ratio * modification factor)} come from, and on what basis are we assuming the mod. factor to be 1.3??
Good day sir. I was given a question of a continuous 1 way slab with a two way at the end. I encountered an issue whereby the area of a bay didn't exceed 30m^2 so what will be my approach in solving for the moments. And also will I treat the end two way slab as a simply supported? Hoping for a swift reply
dr. plz ,,, am struggling getting the need for the 1 width strip in designing slabs.... i cannot understand why we are concerning about the width of the slab and not the length of the slab ?????????? plus how to deal with the slab load which is in kn/m2 while in beam the load in kn/m. Am too confused and i tried to figure out the reason and how it is applicable practically ???? what is the face of simplicity they keep telling about when they use strip method .... plz doc dont ignore my comment.
You can design for the whole width of the slab and get the total reinforcement in the whole width of the slab but this is not practical. It is easier to get the reinforcement in 1 m width and once you did that you easily can know the reinforcement the whole slab. In slabs, it easier when you have the reinforcement for each meter. It is easier for the workers and engineers on site.
@@MrElgamal77 Thanks doc.... yes am still confused doc , i know that it is an approach to ease the calculations , but am wondering do we take the width only because we consider it as beam ???? and why not we say take a strip of 1 meter length ?? why we say width . i could not figure it out >>> also doc , why it is not practical if take the reinforcement for entire the slab at once.
@@user-yz4sr9fs9e in the one-way slabs, most of the load will be transferred in the short direction of the slab. Very minor loads will be transferred across the long direction. Therefore when we design one way slab, we design only the short direction and use minimum steel in the long direction.
You said we don't need to repeat the step for getting total depth in case we realised something is different, I want to know what we are supposed to do in case you realised the diameter has changed.
No. It is a typical range based on M/bd2 and how heavily the slab/element is reinforced and the grade of steel adopted. Look through the table of MF and link it lightly loaded of M/bd2 ranging from 0.75 - 1 with the corresponding Fy adopted and you will see the typical range of that may be used. Enjoy the rest of the day
thank u very much Dr. S .EL Ur channel is very helpful ..... could u recommend me reference which explain how to design ribbed slab with hidden beam ? in BS code
@@MrElgamal77 بعتذر لك دكتور على الإزعاج لكن ليه ما تشرح بالعربي؟..بجد يا دكتور انا بدرس هندسة في السودان وبالكود البريطاني وطول أكثر من سنة بحثت في النت ما حصلت ابدا شرح في الكود البريطاني لكن الحمدلله وجدتك ان شاء الله ببدأ اشاهد الكورس من البداية وأنشره بصفحتي بالفيس حتى يزورا قناتك ويستفيدوا
Dr., how do we know to assume the modification factor as 1.3, is it stated in the codes? or it is practical assumption? And is this modification factor based only on the geometrical properties? Another question I have is if using basic ratio will work designing slab with non-conventional concrete? Thanks so much for the upload. It taught me a lot about design.

Hi Dr. Your videos have been amazing and definitely refreshing to understand this is a better way. I would like to ask a question in regards to the Main and Distribution Bar. Some engineers have been using the Main Bar (BB or B1) in the long span, and I would like to know if this is valid and it can be considered by BS 8110. Thanks in advance from Seychelles
Thank you for your interest and support. For slabs supported on four beams, the main steel should be in the short direction. If the slab is supported on two parallel beams, the main steel should be in the supported direction of the slab because all the load will be transfered to the beams. In flat slabs (no beams) the main steel will be in the long direction.
@@MrElgamal77 Thank you for your response, much appreciated. I see, so even if there is 4 beams it still should be on the short span. Is there any specific calculation available in BS8110 if one decided to change to the long direction? Your response would very be helpful again doctor
@@MrElgamal77 Well Noted Dr. Thank you so much for your responses I'm glad you took the initiative to reply me here Please keep making these videos Thank you again
This is the only channel that simplifies structural design for me
The best video on Reinforced concrete to BScode seen so far.
You are welcome. Many thanks.

Great explanation thnks alot Dr... insh allh give us more vedios about the Rcc
Thank you, Doctor, for the full explanation of the design

Thx so may God bless you
I have been looking for teaching according to BS8110 Thank you Dr . Please also teach on waffle slabs and flat slabs
Very excellent presentation thank you very much
Thank you so much sir this was really helpful wallah please upload more on beams and columns thank you
Thanks. I uploaded 3 more videos about beams. Columns will be next.
Truly clear and very informative! Thank you very much Dr.

How do you determine the conditions of the cover, I mean whether the it's severe or mild
Thanks
Thank you sir
Good explanation🔥
Sir please tell me about the Asp, that how did you get it 513mm in the example video, through which formula and table, please clarify it.
I am using a table that gives you the area and spacing of bars. I show this table in some videos of slabs design.

When you have the reinforcement per meter it will be easier compare different slabs as well.

Nothing. You design are valid with the new diameter.
What should i do if my real modification facor became more that 2???
Thank you very much sir, for your good works, please sir can you do videos on clyprons three moment equation. Thank you sir
نحن بحاجة الى رفد المحتوى العلمي بالعربية ي هندسة . جزاك الله خير
Please do a video about detailing of reinforcement breifly👍
Can you please send me exactly code (tables) that you use it in this course
Thank you for all thing that you do it for us
Thank you for the best explanation Dr can you upload videos of staircase design?
Can you help with a similar video of other types of slab design. flat slab, ribbed etc. thanks
Please also teach on waffle slabs and flat slabs
Many thanks professor. I am student at civil engineering i need the full course of RCc for Bs8110 so please could you help me to get the course??
I am doing this for my students. It is a good idea to give for other students as well. I will think about it. May be later I will do.
شكرا دكتور. ممكن رفع ملفات الشرح؟
10:01 slab thickness and span to use
Dr when you assumed the modification factor for the minimum effective depth to be 1.3, do we always make the same assumption at the start?
No. It is a typical range based on M/bd2 and how heavily the slab/element is reinforced and the grade of steel adopted.
Look through the table of MF and link it lightly loaded of M/bd2 ranging from 0.75 - 1 with the corresponding Fy adopted and you will see the typical range of that may be used.
Enjoy the rest of the day
