Jazakumullahu khiran sir. Best RCC Design Lecture 😊

[@Bluesky_construct2567]

Thanks so much sir. You explain pretty clean and simple and makes one curious of changing the square shape with the aid of analysis and design. Curious to learn more from you sir!

[@jeangc4283]

Great explanations throughout. Thank you!

[@blossomtaye7977]

Good presentation. i liked it.

the best tutorials on line. is there a book available writen by Dr Sharief?

If the deflection is not OK ... what is the what is the way forward

[@paulmwangi5061]

This great sir and very clear,help us also with columns and raft design.

[@mohamedabdullahi2397]

DR SHERIF I don't know ho to thank its very example clear

[@olusegunkehinde5165]

Very Impressed, Thanks

[@MrElgamal77]

Glad you liked it!

[@ahmadsabri_eng]

For the Asmin, Why not go for (T10@275 C/C - Asp=285) ?

[@abdikanisaid3107]

thank you a lot.

can you help me what's problem reference book5-17 For the Wall detail shown below: a. Determine the lap splice length. b. Determine the development length in com- pression and tension for the hooked bars, is the footing depth adequate? c. Determine if the footing width "W" is ade- quate for the development of the footing bars in tension. 2" clr. As (req'd): Footing: 1.0 in./ft? Wall: 0.47 in./ft? #5@8" (vert.& dowels) Lap splice #9@14" W =5'-6" 22 cir. 1-3 --Hook dev. length PROBLEM 5-17

[@onesky5570]

Why do we not check the minimum spacing for slabs and only check the maximum? Do we not need to fund out whether the aggregates etc can fit in between bars?

[@wacomzyademola3431]

Salam alaykun sir, thanks for the lecture, may almighty Allah reward you abdundantly. Please Sir, can you explain how you come about "T10 @ 150mm c/c Asp 523mm ^2.

[@valentineifedayo6626]

What happens if the calculated Area of the main steel(M/0.95fy*z) is less than that of the distribution steel(0.13bh%) ? Which is going to be the main steel reinforcement? What is going to be the Asreq and Asprov when calculating Fs for checking deflection ? I'll really appreciate if you can attend to this very quick sir My exam is next week Monday

[@MrElgamal77]

Use the minimum. 0.13bh/100

[@zoyajawaid2903]

Morning Sir, I have just moved to UK and looking for a job, meanwhile I am familiarizing myself with British Code, recently I got to know that BS8 110 CODE has been superseded by Eurocode 2. Sir can you tell me which code to follow? At the moment I am studying from (Reinforced concrete design- Eurocode 2 by Bill Mosley, John Bungey and Ray Hulse - 6th edition). The design procedures are almost same with your videos except for the code values. Can you tell me which code should I prefer in UK for concrete design and where can I get it from? Thankyou

[@MrElgamal77]

I am not in UK to give you the answer for your question. You need to use the code they are using there. If it is the Eurocode 2, then use it.

[@emmanuelowusu122]

Sir, could you let me know where the “24” comes from in calculating for the self weight in Part 2. I’m lost there. Why 24?

[@MrElgamal77]

It is the denisty of reinforced concrete. 24 kN/m3

[@mieseigha]

Please, how did you get 523mm^2? 10:29

[@okaroh]

My same question

[@mieseigha]

@@okaroh hey, after searching i got how he did it. Cross section area= Pi/4 X (diameter of bar used)^2 Spacing= (cross section area x 1000)/ area required you’ll get ‘180c/c’ but he ended up using ‘150c/c’ Area provided (Asp)= (cross section area X 1000)/ spacing [which is 150 in this case] the answer for Asp will be 523mm^2, that’s how he got it

[@okaroh]

@@mieseigha thank you so much

[@AyubSabr-p1n]

plz giveme reference book assume an 8" one-way slab continuous over 4 total supports. The Clear span between supports is ln = 16'-0". Use f. = 3000 psi and fy = 60,000 psi. Assume d = 6" to the main reinforcing a.Determine the moment and shear values using the ACI coefficients. Draw each diagram assuming a knife-edge support (i.e., ignore the width of the supporting beams). b.Determine the required flexural reinforcing (bar size and spacing) in the slab at the first interior support

[@raphaeldeoliveirafattoripi4110]

Hi sir, Coud you explain me where did you get the As provided when calculating the area of steel, does it come from table? Thanks

[@MrElgamal77]

Yes, correct. We get it from a table. Also, you can calculate them.

[@ramonbaccomperi7871]

Please how do you determine spacing?

[@ar.h.a2543]

شكرا دكتور على هذا الشرح ... عندي سؤال يادكتور اذا تكرمت : البلاطة سماكتها كبير ، ممكن يظهر عليها crack ، هل كافي نوفر طبقه واحده من الحديد او ممكن نوفر لها طبقتين حديد مثل ال flat slab من اجل نتلاشى ال crack ...

[@MrElgamal77]

شكرا لاهتمامك. طبعا يوجد أنواع كثيرة من البلاطات و كل نوع يمكن أن يكون أكثر اقتصادية حسب طول البحر (ابعاد البلاطة). أما بالنسبة لاضافة حديد علوي في مناطق الضغط فلاداعي له اذا تم الاهتمام بعملية الصب و المعالجة للخرسانة بعد الصب. الشروخ في مناطق الضغط على السطح العلوي تحدث بسبب قوي الانكماش نتيجة عدم المعالجة الجيدة للخرسانة بعد الصب او عدم استعمال خرسانة جيدة.

[@rahulkrishnaha3272]

What is main steel < .156, where did u get this value?.156?

[@MrElgamal77]

This is the k value. If k>0.156 this requires compression steel. To learn more, check this video kzbin.info/www/bejne/aXLFdp98gLN3p6M

[@rahulkrishnaha3272]

@@MrElgamal77 ok thanks

[@wacekekirobi6111]

The z calculated was 171mm. Why did you use 180mm in the As(Area of Steel) formula?

[@wacekekirobi6111]

After calculating using 171mm, the result is 447, so never mind. I guess it's a typo.

[@MrElgamal77]

Yes it is.

[@sherifelgamal6707]

Thank you

[@ramonbaccomperi7871]

Please why should the load be multiplies by 10^6

[@wacekekirobi6111]

to convert it from KNm to Nmm

[@shoaibakram1703]

Can you tell me the name of book

[@nesarkhawrin1613]

Sir, what is K and Z?

[@MrElgamal77]

Hello. Check this video and you will know it kzbin.info/www/bejne/aXLFdp98gLN3p6M

[@nesarkhawrin1613]

Thanks sir, also tell me about the Ast, steel area, that how did you get, 350, please I understood rest of the lecture.

[@apatirahameid6109]

How do you know its T10

[@MrElgamal77]

At the initial proporting, we assume it 10 mm. You can assume it 12 with no problem. This will not affect the thickness. At the end, the area of steel will govers if it is 10, 12 or 16..
