U ryt tho..

Hope this structure is strong

My brother, someone has to at least make some professional statements. The misleading and highly erroneous comments I was seeing here forced me to exercise a little patience to analyse the situation.

How's work over at your end?

iksmoore:
I have taken a closer look at the roof trusses of the collapsed building and i cannot but agree that there is a failure in the conceptual design analysis. The loads were not distributed uniformly and there was no support at the center hence the collapse of the roof.Authorities concern should step in immediately to avert reoccurrence .

CXLVII:



These re logical questions and not atheism.

Where was God on that faithful minute?

Why did he allow his house to collapse on his worshippers?

As stated that he knows tomorrow meaning he knew his house would collapse and choose to observe.

A man that has power to divide a sea but can't hold firm a building, re u kidding me?


Ask questions and stop believing in a myth.

Malayy:
bastard.. you think God is a magician.. tomorrow go stand on a highway, and ask why God don't protect your sorry azz when you get crushed to death..

CXLVII:





Your God is not a magician but can walk on water, divide the red Sea, wake the dead, heal the sick and even woke up after death and you still say his not a magician?


Tell me something else that makes him not a magician.

You really cracking me up ere

Malayy:

you are really childish.. all these newbies atheists on nairaland

What are you saying?...are you a civil engineer?I guess you are not, cos of the terms you used? Steel roof systems are meant for long spans (they only need supports at their extreme ends), ie if it's properly designed by a professional and experienced civil/structural engineer. Steel sections are very efficient in performing that function, that was why timber wasn't used or ain't used for long spans. I know this cos I'm a civil engineer, and I have modeled, analysed and designed more complex steel roof systems, with much longer spans.

Now, from the pictures I have seen, the concrete quality is BAD! The columns were under reinforced, the steel roof lost stability due to poor connections between the members and between the trusses and the supporting columns, the diagonals' section sizes and also due to the fact that the columns meant to take horizontal thrust and moment failed in shear as a result of being poorly reinforced (the concrete columns where forced to take tension...concrete doesn't take tension, it.will shear). From the state of the construction site, quacks were in charge doing what to have absolutely no professional idea of.

There's no way they would have had some immediate signs of collapse, cos steel fails plastically(ie there are no warming signs), ie if it was even analysed and designed, which I firmly doubt!

May the souls of the dead rest in peace. AMEN.

wirinet:

I agree with most of what you wrote save the quotes I highlighted in red. From the pictures I have seen, there is no evidence that the concrete quality was bad and also, there is no evidence that the columns meant to take the horizontal thrust failed. From all the pictures I have seen, the roof simply collapsed on itself. It was too heavy to stand. Just look at the size and weight of a single steel truss, then multiply it by the total number used for the whole roof, you will realize the roof cannot stand even place alone on the ground. The concrete pillars and beams were still standing after the collapse.
See this video;

I also doubt the pillars and beams can withstand the weight of the roof for long even if the roof had not collapsed, they look too flimsy.
See the ease with which a small crane snapped the beams and pillars in the video.

I am an architect and not a structural engineer, so I concede competence in such matters to you guys. I am only voicing my opinion.

greenhulk:


This was probably caused by design or engineering flaw or use of substarndard materials. it has nothing to do with wether there's a pillar in the middle or not. An indoor stadium does not have pillar in the middle because it is not needed, the design of this church does not require a pillar in the mddle, just like winners chapel mighty auditorium does not have any pillars in the middle.

feeloscar:
Are you a Civil Engr? Your answer must be no isn't it?

AnodaIT:


I dont think there is need for central support. But I can agree with you about the load distribution, under normal circumstances, loads are designed to induce mainly axial stresses ie to transfer the burden to the pillars by the side.

Take for instance, stadiums with cover roof will not need a support at the center to hold the structure

1stCitizen:
A pillar at the middle would have averted this mishap. The structural engineer should be held accountable

1stCitizen:


I am pretty sure even the engineer at that church would have asked this same question. Speaks volume isn't it?

feeloscar:
Which is why you shouldn't comment on things you know nothing about.

CXLVII:
Let accept that there was a design flaw. The way this peeps preach about how there God can do signs and wonders marvels. It now looks more difficult to believe that a God you serve cannot even protect his worshippers right inside his own house.
