WebGround Shaking A sudden motion or trembling of the earth as stored elastic energy is released by fractures and movement of rocks along a fault. Surface Fault Rupture Displacement (rupture) of the ground surface along a tectonic fault during an earthquake that often results in a a steep scarp. Learn More. Liquefaction
WebVarious types of seismic waves are presented through both actual observations and theoretical interpretation. Their propagation and amplification in heterogeneous geological structures are discussed (soil layers, alluvial basins). The application to site characterization is finally proposed. 2.1 Observation of seismic ground motion 8:22. WebTo model the structural response, we consider 18 2D reinforced concrete (RCC) frames with natural periods varying from 0.14 to 1.55 s; these we subject to over 3500 ground motion records. For various structural and seismological parameters, we then examine the correlations between frames and IMs.
