WebJul 1, 2011 · The duration of strong motion has a significant influence on the severity of ground shaking. In this work, a combination of average values of four geophysical properties of site (Standard Penetration Test (SPT) blow count, primary wave velocity, shear wave velocity, and density of soil) including hypocentral distance of less than 50 km and … WebTo determine the effect of strong motion duration on structural response, ground motion sets of varying durations are used in this study through nonlinear time history analyses. These ground motion sets include both "long" duration records and “standard” records used to benchmark any change in structural response. 2.1 Benchmark Record Sets
Determining strong-motion duration of earthquakes
WebDec 28, 2024 · The distance after which the duration of ground motions for small magnitude events saturate is ∼60 km for shallow crustal earthquakes and ∼200 km for subduction earthquakes. Another difference between shallow crustal earthquakes and subduction earthquakes is the slope of duration versus distance. WebThe strong-motion duration is found to be nearly proportional to the quantity Io/a 2max where a max is the maximum ground acceleration, and Io is the integral over time of the squared accelerations. A less important factor influencing the relationship between so and I o/a 2max is the predominant period To of the strong phase of the accelerogram. cincy grand prix
