The excess pore water pressure generated under the combined vertical and horizontal earthquake excitations is generally greater than that unidirectional excitation, which may further affect dynamic response of soil-pile-superstructure-quay wall (SPSQ) system. This study conducted a coupled effective-stress analysis for SPSQ system to liquefaction-induced lateral displacement excitations. To acc...

Analysis of the earth’s longest period normal modes shows that the December 2004 Sumatra–Andaman earthquake was much larger (Mw 9.3) than initially inferred from surface-wave data and involved slip on a much longer fault than initially inferred from body-wave data. The seismic moment and relative excitation of the normal modes indicate that the entire aftershock zone ruptured, consistent with t...

Ground Motion Definition Earthquake events and realized earthquake ground motions are extremely uncertain even with the present knowledge, and it is not easy to predict forthcoming events precisely both in time and frequency (Anderson and Bertero, 1987; Takewaki et al., 1991; 2013; 2011a; Conte et al., 1992; Ariga et al., 2006; Minami et al., 2013; Çelebi et al., 2014). For example, recently re...

In this study of the dynamics of building-soil interaction, the soil is modeled by a linear elastic half-space, and the building structure by an n-degree-of-freedom oscillator. Both earthquake response and steady-state response to sinusoidal excitation are examined. By assuming that the interaction system possesses n + 2 significant resonant frequencies, the response of the system is reduced to...

in the present paper axial distributions of plasma and floating potentials, electron and iondensities and eedf have been measured in the dl region of a hg discharge constriction. an attempt hasbeen made for the resolution of opposing charged layer structures in dl. excitation processes in theconstriction region are studied. using the linearization method for the nonstationary balance equationss...

Abstract The present work deals with assessment of earthquake-induced displacement the base restrained retaining walls (RW’s). A detailed and rigorous finite element (FE) investigation has been carried out following shaking table experiments on a scaled-down RW model. FE simulations were performed by conducting several nonlinear time history analyses two-dimensional (2D) plane strain model prot...

Abstract An earthquake is a random phenomenon in its intensity and frequency content. Since the signal that contains band of frequencies, each has different energy. This means response buildings to earthquakes depends not only on but content as well. In this study, two approaches have been used: deterministic approach which time history analysis show how affects building response, nondeterminis...
