Piedmont deposits as seismic energy dissipators, Sierras Pampeanas of Argentina

A deformed alkaline igneous rock – carbonatite complex from the 3 Western Sierras Pampeanas

Numerical Modeling of the Seismic Response of Buildings with Energy Dissipators

The poor performance of many framed RC structures in recent strong earthquakes has alerted about the need of improving their seismic behavior especially when they are designed according to obsolete seismic codes. Sometimes, RC buildings show a low level of structural damping, important second order effects and low ductility of the connecting joints, among other defects. These characteristics al...

Hydraulic Energy Dissipators – A Review

Hydraulic Energy dissipators are devices to protect downstream areas of basin from erosion by reducing the velocity of flow up to an acceptable limit. The stilling basins are transition structures fabricated to dissipate excess energy confined by flow with high velocity at the outlet of conduit or tunnel so that the flow beyond the basin does not threaten the firmness of bed and banks of downst...

Embankment dam spillways and energy dissipators

For the last fifty years, the design floods of a number of embankment dams were re-evaluated and the revised spillway outflows are often larger than the original design discharges. Several embankment overtopping protection systems were developed for earthfill structures, and the applications range from river dykes to tsunami protections including embankment dams. Well-known designs include timb...

Crustal thickness beneath the Andes and Sierras Pampeanas at 30 S inferred from Pn apparent phase velocities

[1] We obtained a 2D crustal model beneath central Chile and western Argentina using apparent Pn phase velocities recorded along an EW trending transect at 30 S. This model is characterized by a thick (65 km) crustal root beneath the High Cordillera, a 60 km thick crust beneath the Precordillera, and a gradual shallowing of Moho depths beneath the Sierras Pampeanas from 55 km in the west to 40 ...
