<p>Strong ground motions from the Mw 6.6 2007 Niigata-ken Chuetsu-oki earthquake were recorded by a free-field downhole array installed near the Service Hall at the Kashiwazaki-Kariwa nuclear power plant. Site conditions at the array consist of about 70m of ...

<p>Cyclic1D is a nonlinear Finite Element program for one-dimensional (1D) lateral dynamic site-response simulations. The program operates in the time domain, allowing for linear (Hughes 1987) and nonlinear studies. Nonlinearity is simulated by incremental ...

<p>While site effects are accounted for in most modern U.S. seismic design codes for building structures, there exist no standardized procedures for the computationally efficient integration of nonlinear ground response analyses in broadband ground motion ...

<p>The occurrence of hazard events in geotechnical practice is often associated with geotechnical uncertainties. To prevent hazard events from happening or reduce the impacts of their consequence, sources of geotechnical uncertainties need to be identified ...

Evidence indicates that the vertical component of ground motion is more significant than previously thought, especially for near fault events. However, many design codes do not reflect the importance of the vertical component of ground motion. Therefore, ...

This paper is concerned with the study of the effect of combined horizontal and vertical accelerations on the seismic response of reinforced concrete structures. To achieve this objective, three reinforced concrete buildings representative of rigid, semi-rigid ...

Rotational and vertical components of ground motion are almost always ignored in design or in the assessment of structures despite the fact that vertical motion can be twice as much as the horizontal motion and may exceed 2g level, and rotational excitation ...

<p>The horizontal-to-vertical spectral ratio has become increasingly popular in studies of site effect and determination of the predominant period of a site. In this study, this method is extended to identify nonlinear soil responses. To establish this phenomenon, ...

Scenario earthquakes have been used for the design and safety assessment of nuclear power plant structures and equipments. Scenario earthquakes can be obtained from the deaggregation of Probabilistic Seismic Hazard Analysis (PSHA) results. In this study, ...

Characteristics of vertical and horizontal component strong ground motions have been examined to reveal general trends which may be of significance to structural analyses. Recordings at both rock and deep soil sites representative of WUS showed distinctly ...
