Even since medieval times, fire has been known to weaken the structural integrity of bricks, stones, masonry, and cement.
Fire was a tool often used to weaken castle walls during sieges. It was also known from a metallurgical standpoint, that heat/fire, will change the temper of steel and iron. Its sad, but equally amusing, that this knowkedge , has only become a surprise in the past decade or so. |

The same thing happened last year at a East Harlem building . Residence were saying that it Sounded like a bomb went off. CNN was covering the story. Personally, I believe that the real estate developers, insurance companies, and the banks are behind all these recent fire and explosion in an attempt to displace long-time low-income residences.

A backdraft can sound like a bomb going off, it could also have hit a gas line or some sort of fuel...... |

it was a gas line explosion. The under ground piping in the city is very old. There are always problems in the spring especially right after a hard winter. Manhole ( electrical) fires are almost a daily occurrence. Same with water mains.
Brooklyn Union Gas actually does a great job.. but it is a big city.. 1,000's of miles of under ground pipes |

What usually happens in this type of fire is that a major gas leak lets a large amount of gas into the building. It can come from a gas line below the building, a bad pipe, or a bad connection to a stove or heater. The stinky gas added to the gas line is supposed to give people time to smell the gas before it has an ignition source but a large leak, such as this one, spreads the gas too quickly for people to react.
Gas will not burn without the right amount of air. The gas usually spreads out past ignition sources until the right air/fuel mixture is reached, then an explosion occurs creating an overpressure wave which causes most of the damage. It is the explosion, not the fire that does the most damage to the structure. The resulting fire afterwards, of course, can burn the building to the ground, but in this case the initial explosion caused major damage first. Along these lines, the US military developed the fuel/air bomb where the fuel is sprayed from a cruise missile or similar and the evaporated fuel is then ignited after it has time to evaporate into a gas. This weapon has devastating overpressure and can be used to kill troops or destroy buildings.

The air near the bomb become part of the fuel for the explosion making the effective size of the bomb much, much bigger. |
