Study on Behavior Evaluation of Structures under Various Impacts and Shock Waves
By H. Obi and Y. Sonoda

Concrete Journal, Vol.54, No.7, Jul. 2016


Synopsis
This paper describes study cases on the behavior of RC structures under various impacts and shock waves, based mainly on numerical analysis. The first study case considers the extent of the damage caused to an RC viaduct that goes over a road when a motor vehicle collides with the viaduct. The second study case concerns the degree of damage to an RC viaduct as the result of collision with tsunami flotsam. The third study case examines the structural characteristics of a tsunami evacuation tower designed to withstand the impact of tsunamis and flotsam, when flotsam hits the tower. Finally, the fourth study case examines the application of discharge shock crushing to demolish an RC structure.
