this is an image taken from the northern gaza strip on 8/12/14.
One bomb could have done this. No rebar in the block(cinder block). None of the block is grout filled. Common in non-seismic areas and developing areas.
I've seen buildings reduced to just brick and dust with no reinforcing.
Isn't that rebar sticking out of the structure to the right?
Yes.
I'm glad you are all concrete experts, those are poured in place columns and slabs. The block has nothing in it. The guy standing on the blocks up close you can clearly see that the block wasn't "filled".
Look at the rubble below and notice there isn't much rebar at all.
Again, I've seen this a lot. PM me for pics of other places if you'd like along with my credentials of concrete...

One bomb eh? Are you also a demolition expert? Can I see those credentials too?

One bomb......oy vey.
Now I'm not trying to take away from the devastation.
Ever hear the term "brick and mortar"? Theres's not a mention of "rebar"?!? Engineering has a reason for that.
As for my "demolition" credentials… Doing steel fabrication and modular concrete for 15 years, having ACI credentials and PCI credentials should have some merit on this, but you clearly know more than I do...

Are you sure those weren't stacked after the fact? Looks like it to me. That's not the remainder of a wall or partition if that is what you are suggesting.

I have over 18 years experience in construction. Mostly in steel....I'm a welder. I have a binder full of tickets.....so what? I have no experience in bombs or a war zone.

Yes.

Come on, man... that place is a wasteland.
Yes, correct. They were placed "after the fact" but if they were properly reinforced, filled in, rebar inside, they wouldn't be reusable. Simple fact that most "demolition" goes to the dump.
Look across the street. There is a "floor" of concrete. That's a floor but it was once a ceiling for someone else. It clearly came down.
Now notice that there isn't one piece of rebar coming up out of it?!? So the "floor" or slab was reinforced and nothing else. Poured in place concrete.
Buildings crumble in areas like this because of lack of seismic activity engineering.
If there isn't any seismic activity then no reinforcing is needed…

Fair question!
So you know how to "do" the procedure of welding, smaw, gmaw, Multi position welding, fire watch, "fire wrench" , and know what a 00 and 01 torch tip is?
All that being said you can tell me what was "welded" in those pictures?!?
I'm just telling you what I read. Had the breakdown. You think it's impossible but when you fly 24/7 for 50 days straight, it's possible
I understand what you read. A million bombs dropped on the gaza strip? That is quite the feat.
You're prob imagining these big ass bombs dropping on gaza but they used new, smaller bombs that they dropped on infrastructures as well as homes. But I also could've read it wrong as they dropped 1,000,000 pounds of bombs? But I could've sworn it said bombs.
large scale accounting is in pounds usually. think of ww2 reporting etc. that stilll some weight.

not to far at all. using the tonne weight, thats 400 X 2204.6 lbs. = 881,840 lbs. That was reported on July 9th. well before they stopped til next time.

Developing nations are notorious for inconsistent quality concrete and cement (as I witnessed awestruck with two other structural engineers while overlooking a Four Seasons being constructed in Kathmandu). Due to the difficulty of getting rebar into Gaza, I could see shortages forcing the use of reclaimed (and thus weakened) rebar. I'd assume a structure like this is relying on walls for lateral strength (weakened by grout-free, unreinforced and unfilled masonry), and gravity loads would be on the columns (weakened by reclaimed rebar and poor quality concrete and casting). In addition, construction projects such as these are not likely to have redundancy load paths in place, so you apply a massive eccentric load like a bomb's explosion near a side of the house, and it's very easy to see how the whole thing could go down.
I'd trust tempo to elaborate more as I pivoted my career after less than a year as a structural engineer, but I attended one of two universities in Canada that actually offer certifications in masonry and our program was reportedly greatly subsidized by Canada's concrete lobby.
Edit: Just to be clear, I really couldn't care less how many bombs did this. One bomb or ten thousand - it's too many when they affect the lives of innocents.

Forgot to mention that I've been in the war zones...
You got me man. You're an expert in concrete, explosives and war zones. Probably an expert welder too (you left out TIG by the way) I'm a true believer, one bomb leveled that whole block. The bombing of Gaza in the summer of 2014 was a single bomb. Why is everyone getting so worked up over one bomb? Maybe Israel dropped it by accident.....because it was only one bomb after all. Why don't they just apologize for that one bomb and everyone can move on.
please let's not forget that most quality building materials, concrete, metal bars/rebar, and cement and gravel were banned and not allowed in to gaza under the israeli embargo that was partially lifted in 2012 after israel bombed the shit out of gaza again...
this is one reason most buildings in gaza are less than 8 or 10 stories.

Haha.....I was wondering if that might come up. Good catch.
Isn't that rebar sticking out of the structure to the right?
Yes.
I'm glad you are all concrete experts, those are poured in place columns and slabs. The block has nothing in it. The guy standing on the blocks up close you can clearly see that the block wasn't "filled".
Look at the rubble below and notice there isn't much rebar at all.

I concur.I also know my concrete and applied mixtures and building construction standards.1 bomb or 100s.Some of these structures were coming down just based on how they were constructed.
