<p>The response of shallow sites, with depth to bedrock less than 100 feet, in the geologic and tectonic setting of the Eastern United States (EUS) cannot generally be captured with code-based site factors. The need to address this issue on a regional basis ...

This paper develops an analytical solution to investigate the kinematic response of a batter pile subjected to vertical and horizontal earthquake components (P and SV waves). The pile is assumed to have a circular cross section and perfectly attached to the ...

<p>Current in situ methods used to geotechnically characterize the ground are predominantly based on invasive mechanical techniques (e.g. CPT, SPT, DMT). These techniques are localized to the tested area thus making it quite time consuming and costly to extensively ...

<p>Laboratory tests are often used to understand dynamic soil behavior and to develop cyclic soil constitutive models. However, the loading paths in lab tests are different from those in the field, resulting in the inaccurate prediction of site response. An ...

<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 ...

This research develops a first‐order estimate of the large strain dynamic response of peaty organic soils, with the goal of improving system reliability estimates of the Bay Delta levee network.

<p>Near-fault ground motions often possess distinct characteristics, which can have strong influence on structural response. These include the rupture directivity effect in the fault-normal direction and the fling step in the fault-parallel direction. A site ...

<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>The objective of a site response analysis is to estimate the ground shaking intensity during an earthquake. The Miyaneh city and its suburban areas are located in the northwest of Iran in AzarbayjanSharghi province. This area is prone to high seismic risk ...

In this paper the dynamic response of the ground surface subjected to vertically traveling two dimensional harmonic SH waves in the presence of a single or two canyons is investigated using boundary element method. The models consist of one and two semicircular ...
