title = "Preliminary analysis of correlation between ground response and subsoil softening",
abstract = "Ground motion is closely related with subsoil properties. Under dynamic loading, subsoil tends to soften. Using a ID model to simulate horizontal stratum, the correlation between ground motion and subsoil softening is investigated. Subsoil softening mainly influences ground motion, especially for long period components. Response spectrum intensity relative changing rate is proposed as an index for evaluating the influence of subsoil softening on ground motion. Response spectrum intensity relative changing rate keeps constant when shear wave velocity ratio v′/v0 is greater than 0.2 but increases dramatically with decreasing v′/v0 when v′/v0 is smaller than 0.2. Comparing to subsoil nonlinearity, subsoil liquefaction greatly increases long-period component energy which affects long period structures such as high rising buildings, long span structures.",
