edoyad: The Angular Egyptian Pyramids nko? They were designed to last 27 years

The pyramids were built to last even longer, but there are restrictions to their functionality, plus it's primitive.

The aqueduct the pizza tower and all other monumental European structures were built to last a thousand years or more, thanks to the arch shaped "aesthetic" implemented in their design.

In my research into train station building I noticed that most, if not all train stations in the world have arch shapes in their designs, be it on large doors or windows. sometimes the entire structure is of arch shape.

The arch is significant because, in theory at least, it provides a structure which eliminates tensile stresses in spanning a great amount of open space. All the forces are resolved into compressive stresses. This is useful because several of the available building materials such as stone, cast iron and concrete can strongly resist compression but are very weak when tension, shear or torsional stress is applied to them. By using the arch configuration, significant spans can be achieved. This is because all the compressive forces hold it together in a state of equilibrium. This even applies to frictionless surfaces. However, one downside is that an arch pushes outward at the base, and this needs to be restrained in some way, either with heavy sides and friction or angled cuts into bedrock or similar.
This same principle holds when the force acting on the arch is not vertical such as in spanning a doorway, but horizontal, such as in arched retaining walls or dams.
Even when using concrete, where the structure may be monolithic, the principle of the arch is used so as to benefit from the concrete's strength in resisting compressive stress. Where any other form of stress is raised, it has to be resisted by carefully placed reinforcement rods or fibres.

alpontif: Please stop making a fool of yourself.

Brilliant answer, It was expected.

alpontif: My broda, God bless you, especially for that ''an enigineer has been bastardized in dis part of d world...a technician that fixes phones (not even a technologist) calls himself an engineer.'' part.....

Are you an engineer, if so have you heard of an arch shape before, why is it that most rail stations have it as part of their design, old or new ones?

damilola15: Asking for her registration (and getting it) wouldn't solve the problem of negligence that has plagued Nigeria.

But it's a way forward in holding people in-charged accountable.

You are an id¡ot! A friend came from zambia and visited ALL nigerian airports and said they are sh¡t huh? If you have visited the airports lately, you will see the woman is putting in work and she has not been there forever![/quote]Don't insult him, just ask him which airport he is referring to, since all Nigerian airports are now in top shape.

too bad she is the best aviation minister Nigeria ever had, she must resign.

If GEJ don't ask for her resignation letter asap, I will stop supporting him, And yes the Aviation minister is my sister.

Has she resigned yet?

Yes you are right Ivynwa, we failed them. Nigeria should encourage whistleblowers in all walks of life, so that tragedies like these will be minimised.

VellyG and alpontif, you are both daft cunts, If you two think that that low budget building will stand the test of time then you got another think coming.

olajay5: What is the big deal if you live in the UK? Is that the reason why you are wishing your fellow human being death? Are there no accidents and all other sorts of crime in the UK too? Brother get a life and stop behaving as though you live in heaven.

So you think it's better I keep my mouth shut right. cos I am not wishing anybody death. it's the contrary i wish for.

Beaf: ^
Dude, you are way off line arguing about the structural integrity of the building. You can't tell such things simply by looking.

In this case you can.

The fate of those who fail to take heed to warning is already sealed.

[quote author=Sisi_Kill]You mean how cluless you are?

You don't hafta tell us. . .we already know!! [/quote]Time will tell. Just like peeps were telling Dana air about their planes. we shall see.

[quote author=Sisi_Kill]If his conclusions were based on the fact that he has actually being in the building, walked the length and breadth of it and measured every inch it with the critical eyes that belong only to people with experience in such matters and found the structure lacking then yes. . .indeed he has an understandable reason to be pessimistic.

His "My sister is an architect" and a long time ago,I walked past a technical drawing class and looking at a one sided picture taken from a moving car does not a reasonable conclusion make.

I'm sorry but there is nothing understandably reasonable about his pessimism. Matter of fact, if we want to call a spade what it really is, we can safely say his post is the epitome of illogical reasoning.[/quote]The bold part tells you are clueless on what I am talking about. So I will not argue with you.

alj harem: SMH so you know you are not an architect or structural engineer and you think those factors would not have been taken into acocunt ?

SMH

If they had taking it into account the design would have looked different from that.

jason123: Arosa has an understandable reason to be pessimistic about the building. I see no wrong in it!

Thanks Jason123.

KamiLara: What you going to say about this then (i.e. another southwark council library)

https://blog.emap.com/footprint/files/2009/03/steve-cadman.jpg

I have been in that building and I think it's ok. mind you, it not a rail station (with tens of thousand capacity)and it is not in lagos.

Danka7777: What business does an architect has with "Structural Soundness" of a structure? You should be talking about a structural engineer. Some Nigerians are invariably ignorant and what pains me is that they say this smugly thinking they are right! If you aren't sure of something, shut the Bleep up! I have no doubt people of your type will go and hire an architect to build a house for you and two yrs later, the house has collapsed killing innocent lives.

For the young man that said her sister is an architect, what does that statement mean? What are you trying to say? The fact that your sister has a son, doesn't mean it's your son. Same goes with her profession.

Now, as a structural engineer, by principle of structural analysis, which can be done without being present at the site, it appears to me from the picture that the structure has a substantial amount of columns to support the load/floor above it. In other words, if you analyze the structure in terms of tributary area of load being supported by each column, I am convinced that the gravity loads (live and dead) are distributed uniformly and safely. Now, as to the quality of the materials used and compliance to IBC and ASCE building codes and standards, these cannot be determined without being present at the site.

Lol,

Did your structural analysis, take into account the porous nature of Lagos soil,the constant vibration the building will be subjected to because of the daily train traffic and the fact that thousands of people will be going in and out of that building daily?

mcchegzy: You wont wake coz it will collapse on you

You know i live in the Uk right? I am only drawing attention to your perfect safety regulations put in place for you peeps. have fun in your perfect rail station.

Revolva: Are you better in knowledge than the chinese I don't know why some people are very pressmistic how could you say such balderdash and I am sure you have never been to orile area of lagos before

They are yet to compleyte the mileE part please they should ooo construction work is causing havoc in mile 2 down to maza maza first gate
Good one fashola

An average Chinese is not smarter than me, thank you very much. Do your research on the building works done by the Chinese in Angola. What I will like to know is that this building has passed all necessary structural engineering test required for a rail station in a place like Lagos.

nateevs: And she told you the building doesn't look "structurally sound"?

Wake me up when the building collapses, yawn!

nateevs: No!
Are you?

I did it for just one semester, but my sister is one.

nateevs: And you determine "structural soundness" by looking at a picture online with the building at least 50 yards from the camera?
How do people come up with such stuff?

Are you an architect?

I don't like the design, it doesn't look structurally sound.

tidytim: MP stands for Military Police , Duh !!!

Thanks tidytim, for a moment there I thought that I was in a kindergarten class. MP is indeed military police

have the MP arrested the daft soldiers involved in the shooting?

Cine: You're right and wrong. Yeah, the leaders are the cause of our woes but what have the people here done about it. Most government ministers aren't there to do government work they're there to make money. So why should they change the system. They'll replace themselves with a clone and continue to reap rewards.

It's for the people to change the system not the people benefiting from the system because that won't happen.

You have move on to the solution of the problems already. nice one! It's just that the people don't know how to go about holding their "elected leaders" accountable. So who is going to teach them?

lonelypal: For a perfect Leadership to thrive and drive towards a sane and desired society, it starts with the following steps from both parties:
1. Having the right mindset to lead and be led
2. A suitable symbiotic relation needs to exist between the followers and its leaders AND MOST IMPORTANTLY.
3. Bearing in mind that the leaders are the products of the society they seek to govern, a total overhaul, attitudinal and oriental change towards Leadership needs to be imbibed by all and sundry
Hence the reason for my TAKE ON THIS TOPIC 'NIGERIANS need RE-EVALUATE and have ATTITUDINAL CHANGE towards various facets of life, societal values'

In my own humble opinion , the first point of call to implement this approach towards achieving the desired CHANGE in our society will be THE FAMILY (being the smallest unit of the society), the next being your interaction with your NEIGHBOUR and the effect of these chemistry continues on to engulf the entire society.

How can you get 160million Nigerians with diverse views in religion and tradition to start thinking the same way, given the fact that Nigerians love corruption so much?

[quote author=Olu_Bendel]In every society and human setting there always is leaders/followers, be it democratic, religious, traditional, constitutional etc.Now,in well evolved societies, these top echelon (elites) make sacrifices for the lower echelons (Masses), these elites are well concious of the need for the survival and growth of that society, they make laws and pursue equality in its enforcements.They fight and bricker amongst themselves when the interest of the society is at stake. In Nigeria, the only time the elites fight among themselves,if they ever do is where they have lost out of a contract,oil block or out-rigged. Never where a school contract, road construction or hospital project is poorly executed (leading to losses in lives). Even when they make feeble attempts at probing themselves, a la oil subsidy/power probes, nothing ever comes of it. Until have more of Gani fawehinmis, El-rufais, Shehu Sanis, Dino Melayes,Wole Soyinkas, Chinua Achebes, Smart Adeyemi's,Keyamos, Dora Akunyilis, Chukwumerijes, Isa salami's (elites who are ready to sacrifice their personal comfort and confront the status quo for the general good of all) our elites will continually manipulate us to believe whatever they want.[/quote]I am very happy to read your post, I wish all Nigerians will think like you on this topic. I thank God for your life.
