Earth Dam‐foundation interaction during earthquakes

Earthquake Engineering & Structural Dynamics, 1973
AbstractSeveral significant parameters that could affect interaction in a dam‐foundation system are discussed. These parameters are: (1) Fundamental periods of the dam and the foundation layer. (2) Lateral extent of the dam. (3) The material properties of the dam and the foundation layer.

Fragment-Asperity Interaction Model for Earthquakes

Physical Review Letters, 2004
A model for earthquake dynamics consisting of two rough profiles interacting via fragments filling the gap is introduced, the fragments being produced by the local breakage due to the interaction of the local plates. The irregularities of the fault planes can interact with the fragments between them to develop a mechanism for triggering earthquakes ...

Earthquake Interaction for Multistory Building

Journal of the Engineering Mechanics Division, 1972
The earthquake responses of multistory buildings are studied taking into account the soil-structure interaction effects. Fast Fourier transform techniques used to obtain the frequency-domain responses (transfer functions) and time-domain responses (time histories). The results show that the floor accelerations, distortions, and story shears are largest

Structure-Wave Interaction Under Earthquake Excitation

Journal of Offshore Mechanics and Arctic Engineering, 1990
Abstract A method for the hydrodynamic analysis of large bottom-fixed offshore structures under earthquake action is presented. The investigation deals with arbitrarily shaped vertical bodies of revolution, to which the so-called macroelement method can be applied.

Interactive Visualization to Advance Earthquake Simulation

Pure and Applied Geophysics, 2008
The geological seiences are challenged to manage and interpret increasing volumes of data as observations and simulations increase in size and complexity. For example, simulations of earthquake-related processes typically generate complex, time-varying data sets in two or more dimensions.

Earthquake Interaction by Fast Fourier Transform

Journal of the Engineering Mechanics Division, 1971
A simple approach using a Fast Fourier Transform (FFT) algorithm for obtaining the transient structural response to earthquakes is presented. Two different foundation models are used, a rigid circular plate and a rigid two-dimensional strip bonded to the elastic soil half space.

Reservoir-dam interaction during earthquakes

Bulletin of the Seismological Society of America, 1967
abstractMost work, to date, on analysis of effects of earthquakes on dams treats dam and reservoir as two uncoupled systems. The importance of interaction between the two systems in determining the water pressure on dams during earthquakes is investigated herein. The analysis presented is approximate in nature and is aimed at exploring the problem. The

Social Interactions in High School: Lessons from an Earthquake [PDF]

SSRN Electronic Journal, 2006
After an earthquake hit Southern Italy in 1980, young men from certain towns were exempted from compulsory military service. We show that the exemption raised high-school-graduation rates of boys by more than 2 percentage points. We do this by comparing high-school-graduation rates of young exempt men and older nonexempt men from the least damaged ...

Earthquake Prediction and Disaster Preparedness: Interactive Analysis

Natural Hazards Review, 2010
Recent studies in earthquake predictions, having time windows of several years and possibly down to several months, have led to a reformulation of the intertwined problems linking disaster preparedness with earthquake prediction. Given an earthquake prediction including a time window, magnitude, probability of false alarm, and geographic area, disaster

Soil-Pile Structure Interaction during Earthquakes

Geotechnical Engineering for Transportation Projects, 2004
Seismic soil-pile structure interaction (SSPSI) is a complex process involving several, simultaneously occurring and, sometimes compensating phenomena. To better appreciate SSPSI, the physical processes that occur when a pile supported structure is seismically loaded are first categorized into far-field effects, near field effects, and inertial effects.
