The structure disintegration isn't quite real, as I can't get it more realistic with this fancy fx-eng (at my skill level of course). Anyhow many of those buildings seen here are glass-like material, I think. Too rigid, and shatters all the way on collision.

This model combines both "rigid body" breakable hinges and some pieces going through each other which allows the structure bend first, and within certain force, collapse.

It's like titanic going in pieces ripping and bending and breaking..
