Earthquake-Induced Domino-Type Progressive Collapse in Regular, Semiregular, and Irregular Bridges

Figure 15

Second type of progressive collapse of bridges (a) in analysis: (A) stable condition, (B) initial crack at the connection of deck and abutment, (C) falling down of the first span deck on the ground and large rotation of deck at pier bearing, (D) fracture of adjacent span at distance of 0–0.1 L (E) the same mechanism occurring for adjacent span, and (F) propagation of collapse in the bridge; (b) in practice.
