Abstract: For stiff structures with large plan dimensions, on soft soil and supported by columns on separate foundations, differential motion of the column foundations may lead to large moments and shear forces in the first-story ...

Abstract: A method for the synthetic generation of curvograms (curvature versus time) associated with strong earthquake shaking is presented. It is shown that small radii of curvative of ground motion, in the range of several hundred ...

Abstract: An empirical, energy-based methodology for liquefaction hazard assessment and microzonation mapping is presented. The approach is probabilistic, considers the uncertainty in the liquefaction criterion, and is applicable ...

Abstract: Simplified response of buildings with a soft first floor and excited by propagating wave motion at the base are studied, so that the physical phenomena associated with phased input excitation can be characterized. Analytical ...

Abstract: Qualitative analysis of the antiplane vibrations of long structures shows that the dynamic response to excitation by ground waves can be described by the translation of the foundation only if η (ratio of the length of ...

Abstract: In this paper, the physical phenomena associated with wave passage under long buildings have been studied. A two‐dimensional, continuous model has been used to represent the building vibration. Analytical, closed‐form ...

Abstract: Following the 1994 Northridge earthquake, the areas with a high density of reported breaks in water pipes in typical residential areas in San Fernando Valley and in Los Angeles often did not coincide with the areas having ...

Abstract: Peak ground accelerations recorded during the Northridge, California, earthquake of January 17, 1994 are described in relation to the observed, nonlinear soil response. Four attenuation relationships were developed ...
