Stale news, dat no longer happen in ketu

tintingz:
What a big lie.

The OP picture was shot when govt did barriers across the road preventing people from crossing, people were not able to cross, they had to make use of the pedestrian bridge, this picture is NOT a recent picture of the bridge.

There are roof pillars by the side handle of the bridge, the govt wants to roof the bridge, from the OP pic there are no roof pillars, this is an old news/pic.

don't mind the twatt with fake news!

Just release small fart now, everywhere will be decongested.

Additional one should be built immediately. No way they will consider it waste of money until that one breaks and kill people.

babatgtr:
This what happen when we can't use the power of unity, if all this people can cross at the same time who will arrest them... The government should know that this bridge is too small for that area.

ignorance

law enforcement agency will only pick selected few people.

he should av log on to citizensgate.lagosstate.gov. ng for any suggestions, complain and enquiries. it s d best place to do that. I once complain about d new Berger Pedestrian bridge as d pillar dat carry bridge at d centre is not guided or shielded against any accident. thr response was just too rapid. kudos to lagos state govt on that development.

Hey,
u wey dey pass dis brige make u hold ur pocket well ooo....

Wiseandtrue:
That environment and Ojota is highly populated. Government needs to act fast!

i moved out from ojpta last year because of the cultism there

slurryeye:

I'm not a civil engineer neither am I a civil engineering student. I'm just a student of common sense

well, if the bridge was built by a real engineer nothing can be happen to it cos D engineer would have made proper provision for situation lyk dis....common sense doesn't apply to everything thing

OP, you are very greedy and selfish. Na you post story and na you be first to comment. Make you dey collect our blessing you hear.

There is a second brand new Pedestrian Bridge not far from this one. It has been completed and is awaiting commisioning. I suggest it should be opened to pedestrian traffic ASAP to ease the traffic on the only existing one. Eko oni Baje!

Sorry i mistook it for the one at Ojota

I stopped going there when that over head bridge was introduced. People plenty you no go see where you go put leg. Come see odour... chai no small somchin

Wow population density is something. They better make more bridges finish that mass rail line. I would feel unsafe crossing that bridges. People can pickpocket and push u off.

The bridge was one of the reasons i moved out. The queue back and forth

Are you for real? A professional engineer will make provision for a situation where hundreds of people will be standing on a bridge at the same time?
Do you even know what tensile strength of a material is?
Do you know that due to brittle nature of concrete, there is a limit to the tension it can withstand?
You must be kidding with that your comment

smh so that whole structure was built with just concrete. you've never heard of reinforced concrete. when you've had year 1st construction experience come back here to argue

Reinforced concrete? Dude you know absolute nothing, and you sound rude. Telling me to go get 1 year construction experience before I argue. First of all, I'm not arguing with you dude. Secondly, if you care to know I'm a mechanical engineer practicing in Canada with over 9 years experience.
Now that you know I'm a professional engineer, let's talk in engineering term
Let's assume the average weight of the people standing on the bridge is 140 pounds, since an average person occupy about 1.5 square feet while standing, this implies that one person is applying an average of 6psi on the bridge. Looking at that picture, it won't be wrong to assume that more than 600 people were on the bridge. This means that about 3600 psi of force is applied on the bridge constantly. Now tell me the tensile strength of a reinforced concrete, and how it could withstand 3600 psi of force consistently subjected to.
I guess you are one of those people building houses that keep collapsing and killing people in Nigeria.
Next time you want to talk to someone rudely, first fvcking know who they are first

I can swear on anything u are no engineer. So bridges meant for car built with same materials also collapse? since a car weight is more than a normal human weight since you're talking about tensile strength

Bro stop you left your self open for easy counter arguement. Foot bridges aren't meant to accommodate cars. The material is built with around certain engineering parameters. Your arguement is akin to saying just because a concrete road holds cars it means it automatically meant to host heavy traffic from heavy vehicles like highway.

Dude please don't quote me again, if you don't know the difference between structural components of vehicular bridge and pedestrian bridge. Since houses and vehicular bridges are made of concrete you might as well start parking or driving your car on your decking.
I just scroll through your profile now, and I see that you're 300 level civil engineering student in Uni Ilorin. You are a disgrace to the university and all the lecturers that have lectured you from 100 level for you not to know there are differences between structural components of vehicular bridge and pedestrian bridge. Go ask your structural engineering lecturer to explain the differences to you before you graduate because I fear people that give job to you after you graduate. In order to safe lifes, is either you quit engineering or start all over from 100 level to gain the knowledge you might have missed.
I'm not here to educate an ignorant like you. I repeat, don't quote me again

I didn't really mean that. I only said that to counter is point where he said concrete has poor tensile strength when there are many technologies now to improve its tensile strength. of course the mix ratio will be diff and some other materials added

slurryeye:
What is this eyesore for God sake?

You don't need to be a civil engineer to know that the tensile strength of the concrete used for the construction of the bridge was not meant to carry so many people.

If the bridge eventually collapse and hundreds of people die, you will start blaming devil and ask for God's mercy

Instead of waiting for the time to blame the devil, why can't we find a way to solve this problem.

My suggestion is for the government to build a traffic light with predestrian crossing one kilometer apart on the road. The traffic light should turn to stop every five minutes during rush hour, and 60 seconds giving for pedestrian light for people to cross. This traffic light should be regularly monitored, and any motorist seen violating the light should be charge with manslaughter. We should learn how to value lifes more in Nigeria

Please tell me you are not a civil engineer. Tensile strength of Concrete! There is God

As a civil engineer, what you would have done is to tell me that the tensile strength of a portland cement concrete is between 300 psi to 700 psi, and prove that the design of pedestrian bridge is meant to consistently carry over 600 people at once.

I should have, I am sorry for the way I reacted. Though it is not fashionable to even acknowledge the tensile strength of concrete since it is negligible, especially when compared to that of rebar, so naturally I expected the only strength of concrete worth discussing is its compressive strength.

now concerning the design of the pedestrian bridge, one would need to see the design report to assess the adequacy of the structure based on the imposed load that the designer anticipated in the life of the structure. In the abscence of that, we can only guess the integrity of the structure except there is a visible indication of failure of the structure or better still carry out NDT and holistic structural health assessment.

Thanks very much for the explanation. Though I'm not a civil engineer, but as an individual, it looks bizzare to me for hundreds of people to stand on a pedestrian bridge that surely wasn't design for that purpose. If I'm in position of power, I won't allow so much people to be on the bridge at the same time just like I won't allow up to 80 people to stand on my balcony. That being said, we know the maintenance culture of Nigerians, and the fact that the said structural health assessment and Non Destructive Testing won't be done to curb unforseeable collapse. In order to avoid such disaster, why can't we provide an alternative.

I understand. I am a Civil engineer and have spent most of my career designing such infrastructures, why i said we would need to see the structural design and calculation report first is that most times due to the fact that in nigeria one can not corectly predict even quality of materials, how much more the loads a structure would be exposed to, we over design. There was a case of a govt secondary sch that was originally billed to hold 40 students in a class, after construction govt simply moved students from two schs it handed over to missionaries into it, as a result some classes held as much as 120 students, thankfully i envisaged such and adopted a very conservative design. Typically when conceptualizing a structure, we design for robustness, accidental loads and ensure utilisation ratios are below unity to have some reserved capacity. Though even with such a conservative design, a structural integrity investigation is paramount to confirm the structure is safe under such use.


Honestly from my practice, I have learnt nigeria is a joke, a place where doing the right thing is viewed as a waste of time, where no one ever aprreciate technicalities and details. Right thing to do is simply another bridge to reduce the stress on this one but who cares?
