No ve not written buh if I score 68/70

CaptainEColeJnr:
hmmmm.. pharmacy is as competitive as medicine ooo.
Is either you're given MBBS or educational courses.. or perhaps optometry, health science!

buharisbae:
so u mean they can't gimme sumtin lyk pharmacy or dentistry even with that high score

Fynestboi:
Baba how far

refiner:
...awwwwwww..thanks sweety!.*wipes out tears*..hand me your handkerchief too,mine is already soaked!...


yea,the voting is yet to kick-off....before then,I'll let you know ok!....

refiner:
....so I'm not worthy to get a vote from you?....*starts sobbing!*

This is a waffle slab with permanent shuttering (former). Waffle slab is a slab with rib beam in two direction (different from ribbed slab with rib only in one direction.
The ribbed are space at a regular distance between each other based on formers, life load and code specifications.

Waffles slab is made up of
1. Topping
2. Series of rib beam accros both the short and long span of the slab.
3. Former ( the bubble above, hollow block, clay block, plastic pod, polystyrene pod etc) which remain part of the construction after the Formwork is removed.

In most cases the waffle slab is designed in such a way that the topping is not consider to contribute to structural strength but only to linked the rib beams together. The topping can also be made of concrete of not necessarily of the same strength as that used in ribs.

The former (polystyrene pod, bubble or clay block) are not consider to contribute to the slab strength in the design calculation most time.

The major advantage of these floor is the reduction in weight achieved by removing part of the concrete section below the neutral axis and replacing that with lighter weight materials. These types of construction are economical for building where there are long spans, over between 5m to 6m with light to moderate life load (1.5 - 3kN/m2), such as residential houses, schools, hospital, hotels etc. They would not be suitable for floors having heavy load like warehouse, production facilities, garage etc

abdulwastecx:
There are beams but these beams are of the same depth as the rib ( the small beam of the waffle). These beams are wider than normal beams in solid slab construction ( width greater than 225mm in most cases).

Check out the following books
1. Reinforced concrete: design theory and examples ( first and second edition) by T. J. MACGINLEY and B. S. CHOO

2. Reinforced concrete design to BS8110 - simply explained (A H ALEN)

3. Reinforced concrete designer's handbook (C E reynolds and J C Steadman.

4. Reinforced concrete design ( Bill Mosley, John Bungey and Ray Hulse).

These books were very helpful to me during my undergraduate years on reinforced concrete design.

I will also advice you to get all the BS 8110 for reinforced concrete design, steel table and structural detailing to Bs 8110. You need to also get BS 6399 loadings for building. These codes will make it easy for you to do your design.

Structural design requires lit of simple mathematics unlike structural analysis that requires advanced and vigorous maths. What you need to do is devote more time to it, understand all the steps involved and prepare your mind towards it.

During my undergraduate years, grade (gp) was secondary to me, understanding the design was more important to me. I study these things to be able to do the design, so I use lit of practical examples like working real architectural drawings instead of those simple panels giving in the classrooms.

It increases the head room in floor by eliminating drop beams in slabs.


modified one of the site am currently working on.

All method of slab construction requires close supervision and clear mathematical calculations.
Waffle slab is as straight forward as one - way solid slab or two - way solid slab, I think flat slab is more technical than even this waffle slab.

For all type of slab you need the right steel strength and concrete strength.
A one way slab behave like a continuous beam where the span is sagging ( bottom Fibre is in tension) while the continuous support is in hogging (top Fibre at the support is tenaion).

A two way slab behavior is dependent on the end conditions and for this type of slab we have about 9 different end Conditions, namely
1. Interior panel
2. All edges discontinuous
3. One short edge discontinuous
4. One long edges discontinuous
5. Two short edges discontinuous
6. Two long edges discontinuous
7. Adjacent edges discontinuous
8. One short edge continuous
9. One long edge continuous.

For these two way slab design code is use to determine both the positive and negative moment for design purpose.

For ribbed and waffle slab.
Ribbed slab is like a one way slab where the solid concrete section is replaced with series of ribbed parallel to one another at a reasonable space based on the life load, span of slab and the type or former to be use. It is made up of topping, rib beam and former which can either be temporary or permanent. The analysis of the rib is carried out like that of one way slab where the span and support moment and shear is gotten through beam analysis or using appropriate formulas from bs codes.

Waffle slab is like two way slab where the rib beam is in both directions. The ribbed intersect each other to form a box that is either filled using polystyrene, clay block or sancrete block.

Keep forcing Nigeria to diversify from oil
Keep the bombs rolling

Who knows, you guys might just be a blessing in disguise.

farano:
In my own opinion, I don't think it's proper to call only the promiscuous girls prostitutes and the guys are referred to as players, a term applied to boost their confidence . Both women and men who sleep around should be called 'Prostitutes'

What do you think?

podosci:
Attached to this trend is my specially designed spreadsheet to simplify moment calculations for civil engineers and also for Students to use to better understand Reinforced Concrete Analysis and Design. The Engine of the calculation sheet was three moment equation by Clapeyron, Feel free to ask Questions especially for Civil Engineering students

pmn was just a piece of garbage then like he is now.an illiterate will always be inconsequential & ineffectual.

When it was within 320 - 321, we saw how a set of people usually flood here to jubilate over it. Today, it's 317 now and hopefully it would go down to 250 before the 2nd half of the year.

Oh ye celebrants of bad news, flood this thread and celebrate this as well!

Why small allocation to d north??

jossy26:
by saying hes too theoretical i only meant hes using too many jargons on a public forum where many wouldnt understand, so many others wants to learn but when someone is becoming too technical you find it difficult grasping anything,

RickyTan:
Dont be fooled by the rubbish lines that Fulani man IBB drew. Our people OWN ASABA

Thrash!

Delta is igbo state. Now go and hang

. Is Asaba not igboland? Proudly Asaba boy, proudly Igbo. Haters should goan die
