WebSignificance and Use 2.1 The seismic crosshole method provides a designer with information pertinent to the seismic wave velocities of the materials in question (1).2This data may be used as input into static/dynamic analyses, as a means for computing shear modulus, Young’s modulus, and Poisson’s ratio, or simply for the determination of … Webpull-up. 1. n. [Geophysics] A phenomenon of relative seismic velocities of strata whereby a shallow layer or feature with a high seismic velocity (e.g., a salt layer or salt dome, or a carbonate reef) surrounded by rock with a lower seismic velocity causes what appears to be a structural high beneath it.
WebTypical standard protocol compared to simulated building inter-story drift earthquake response (Maison et al., 2016) Reports on lab tests often do not discuss how a component response is influenced by the loading protocol, so engineers are left to accept the results as intrinsic “seismic” properties.
