Abstract Near-fault ground motions may contain impulse behavior on velocity records. To calculate the probability of occurrence impulsive signals, a large dataset is collected from various national data providers and strong motion databases. The has number parameters which carry information earthquake physics, ruptured faults, parameters, distance between station several parts fault. Relation s...

Uncertainties of the ground motions and structural parameters are main factors that limit accuracy embankment seismic fragility assessment. In response to uncertainties motions, artificial synthesizing method near-fault pulse-like was proposed, 15 with rupture fault distances ranging from 1 km were synthesized by taking Chi-Chi earthquake in Taiwan, China, as an example. The Xi’an-Baoji express...

Endurance Time Method (ET) is a dynamic analysis in which structures are subjected to intensifying accelerograms that are optimized in a way that seismic performance of structures can be estimated at different hazard levels with the best possible accuracy. For the currently available ET accelerograms, regardless of the shaking characteristic, an excitation level is recognized as a representativ...

Intensive seismicity was often observed in the front of tabular stopes in South African gold mines. The seismicity was usually caused by high stress concentration due to excavation, and some of the seismic events were fault rupture events. This study focuses on numerical modelling of seismic wave propagation resulted from a moment magnitude Mw = 1.4 seismic even...

Near-source ground motion at four azimuths but constant epicentral range 1s computed from a buried circular strike-slip fault in a half-space. Particle acceleration, velocity, and displacement at each station on the free surface is computed in the frequency band 0.0 to 5.0 Hz. The assumed dislocation is denved from the Kostrov (1964) displacement function for a continuously propagating stress r...

This comment addresses a discrepancy between the results obtained by Wald et al. (1990) and Frankel and Wennerberg (1989) concerning seismic slip during the 1987 Superstition Hills earthquake (M s 6.6) in southern California (Fig. I). Both studies used strong-motion records to locate subevents that produced the high-frequency (__> 0.5 Hz) strong ground motions for this earthquake. Wald et al. (...

the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...
