Abstract: One-dimensional ground response analyses (GRAs) are often used with an expectation that they provide unbiased estimates of site effects. Under that hypothesis, epistemic uncertainty in site response arises mainly from ...

Abstract: Earthquake strong motion recordings from 29 sites with instrumented structures and free-field accelerographs are used to evaluate variations between foundation-level and free-field ground motions. The focus of the paper ...

Abstract: The failure of the Tapo Canyon tailings dam was one of the most striking failures of an earth structure to result from the January 17, 1994 Northridge, California earthquake. The failure involved a 60-m-wide breach of a ...

Abstract: Evaluation of ground failure potential in geotechnical practice is typically based on demand parameters that solely consider vertically propagating shear waves in the free-field. Soil–structure interaction (SSI) modifies ...

Abstract: The assessment of earthquake-induced demand in the soil supporting a structure is commonly carried out in terms of stresses and should consider three components: (1) geostatic stresses; (2) stresses due to wave ...

Abstract: Foundation impedance ordinates are identified from forced vibration tests conducted on a large-scale model test structure in Garner Valley, California. The structure is a steel moment frame with removable cross-bracing, a ...
