Abstract Recently, the reinforced cement concrete (RCC) frame has been one of most commonly used structural systems for buildings in high seismic region due to its inherent earthquake-resistant property. However, there is still a deficiency understanding RCC building system dynamic behaviour during significant earthquakes. A 1/4th scaled framed structure tested on shake table present study. The...

Contrary to predictions of the tidal torque model, length of day (LOD) decreases over a series of fluctuations since 1960s at least. The so far deepest LOD depression of 1997 – 2010 corresponds to the most prominent rises of total seismic activity and global mean temperatures. A conspicuously flat interval of the LOD curve uniformly at or slightly below –0.1 ms level in 2001 – 2005 roughly coin...

[1] Triggered earthquakes can be large, damaging, and lethal as evidenced by the1999 shocks in Turkey and the 2001 earthquakes in El Salvador. In this study, earthquakes with Ms 7.0 from the Harvard centroid moment tensor (CMT) catalog are modeled as dislocations to calculate shear stress changes on subsequent earthquake rupture planes near enough to be affected. About 61% of earthquakes that o...

This study investigates the seismic response of a horizontal axis wind turbine on two bottom-fixed support structures for transitional water depths (30-60 m), a tripod and a jacket, both resting on pile foundations. Fully coupled, nonlinear time-domain simulations on full system models are carried out under combined wind-wave-earthquake loadings, for different load cases, considering fixed and ...

The depths and source mechanisms of nine large shallow earthquakes were determined from long-period (150 to 300 s) Rayleigh waves recorded by the Global Digital Seismograph Network (GDSN) and International Deployment of Accelerometers (IDA) networks. We inverted the data set of complex source spectra for a moment tensor (linear) or a double couple (nonlinear). By solving a least squares problem...

En la actualidad son muchas las situaciones y necesidades de las personas para mantener o recuperar su salud o sus condiciones de vida óptimas, que van a requerir de la combinación de respuestas de atención que articulen intervenciones de apoyo desde el sector sanitario y desde el sector social, que permitan una atención integral e integrada a estas necesidades. Podemos destacar situaciones crí...

[1] Radar interferometry (InSAR), field measurements and creepmeters reveal surface slip on multiple faults in the Imperial Valley triggered by the main shock of the 4 April 2010 El Mayor‐Cucapah Mw 7.2 earthquake. Co‐seismic offsets occurred on the San Andreas, Superstition Hills, Imperial, Elmore Ranch, Wienert, Coyote Creek, Elsinore, Yuha, and several minor faults near the town of Ocotillo ...
