The possibility of inertia force in the superstructure and liquefaction-induced flow is low as the main cause of the collapse of the Showa Bridge. There is a high possibility that it was due to increased displacement of the ground in circumstances where pile deformation occurred more easily due ...
Testimony from eyewitnesses of the Showa Bridge collapse was collected with the objective of pinning down the cause of the collapse. On the basis of this testimony, a chronology of events was established. The bridge collapsed about 70 seconds from the beginning of the earthquake, i.e., long ...
for example, have designed a structure equipped with structural "fuses" that, instead of toppling, deliberately collapse upon themselves and then reform after the quake subsides [source
11b illustrates a case where complete collapse of masonry on one side collapsed completely, while similar structure on the opposite relatively minor damage. This contract suggests the variation in the bedrock and difference in ground shaking intensity in two sides of the road. The areas with sand ...

The 1-5/1-605 separator, a major nine-span bridge, was severely damaged in the Whittier earthquakes. All columns of Bent 6 suffered shear failures and the supported spans came close to collapse. Other minor damage included column hinging at more flexible bents, abutment pounding and fr...
We explain this by considering that the ground-shaking energy generated by the mainshocks is large enough to cause weak and unstable landslides close to the epicenters to collapse shortly after the earthquakes, but the earthquake-induced energy in the far field is relatively weak and gives rise ...

Southwest of Arvin, on the San Joaquin Valley floor, ground cracks traversed and split the concrete foundation of one house, causing partial collapse. The ground slumped; cotton rows were offset more than 30 centimeters; and pavement on one highway was crumpled for more than 300 meters. East ...
