First types of progressive collapse of bridges (domino-type progressive collapse) (a) in analysis: (A) stable condition, (B) initial crack in abutment support, (C) falling down of the first span deck on the ground, (D) collision of the other side of the deck with pier, (E) shear fracture of pier and instability of second span, and (F) complete collapse of first span; (b) in practice.
