Brazil is in an intraplate area of low to moderate seismicity, this means that few or no records strong ground motions are available. Part the site response analysis and seismic design structures require use acceleration time-histories compatible with a specified target spectrum. This study aims utilize methodologies based on existing earthquake from well-known database synthetic accelerograms ...

S U M M A R Y Seismic interferometry is now widely used to retrieve the impulse response function of the Earth between two distant seismometers. The phase information has been the focus of most passive imaging studies, as conventional seismic tomography uses traveltime measurements. The amplitude information, however, is harder to interpret because it strongly depends on the distribution of amb...

Lightweight steel framing is a method in housing and construction that have been widely used in lightweight steel construction. In this method, the structure is built by cold formed steel elements. They are cost-effective, light, and easy to assemble. However, the performance of lateral load resisting systems in cold-formed steel structures specially the behavior of cold-formed steel shear wall...

Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and hence neglecting this phenomenon in analysis and design may lead to an un-conservative design. The objective of this paper is to quantify the effects of nonlinear soil-structure interaction on the seismic response of a low-rise special moment fram...

In areas of oil and gas exploration, seismic lines have been reported to alter the movement patterns of wolves (Canis lupus). We developed a mechanistic first passage time model, based on an anisotropic elliptic partial differential equation, and used this to explore how wolf movement responses to seismic lines influence the encounter rate of the wolves with their prey. The model was parametriz...

Identification of similar Turbidite features on well log and Seismic There have been many studies of how Direct Hydrocarbon Indicators (DHIs) can help or hurt us when trying to distinguish fluid and lithology effects on seismic amplitudes. The integration of outcrop studies can enhance the interpretation of complex reservoirs in deep-water depositional settings. In this paper we present observa...

The corner frequency of the spectrum of particle acceleration in a seismic wave radiated by an earthquake source marks the transition between the low-frequency band, in which the spectrum rises as frequency squared, and the high-frequency band, in which the spectrum is flat. These two distinct bands are controlled by different characteristics of faulting. The low-frequency range is governed by ...
