The failure points were the same: walls and slabs not tied properly into columns -- that's a roof slab hanging off the building -- cantilevered structures, or structures that were asymmetric, that shook violently and came down, poor building materials, not enough concrete, not enough compression in the blocks, rebar that was smooth, rebar that was exposed to the weather and had rusted away.
I punti di cedimento sono gli stessi -- muri e solette non fissate adeguatamente alle colonne -- una parte del tetto pende dalla struttura -- strutture a cantilever o strutture asimmetriche, che si sono scosse violentemente per poi cadere, materiali di costruzione pessimi cemento insufficiente, insufficiente compressione nei blocchi, tondini lisci, tondini esposti alle intemperie quindi arrugginiti.
