We examine the long-period near-source ground motions from simulations of M 7.4 events on a strike-slip fault using kinematic ruptures with rupture speeds that range from subshear speeds through intersonic speeds to supersonic speeds. The strong along-strike shear-wave directivity present in scenarios with subshear rupture speeds disappears in the scenarios with ruptures propagating faster than...

Motivated from the quadratic dependence of peak structural displacements to pulse period, $T_p$, pulse-like ground motions, this paper revisits $T_p$--$M_\text{W}$ relations motions generated near-source earthquakes with epicentral distances, $D\leq$ 20 km. A total 1260 are interrogated wavelet analysis identify energetic acceleration pulses (not velocity pulses) and extract their optimal ampli...

On 8 January 2022, an M S 6.9 earthquake occurred in the Menyuan county, Qinghai province at northeastern margin of Tibetan Plateau. A dense observatory network consisting accelerographs and intensity meters has obtained many acceleration recordings this region, which previously had only a few strong motion recordings. Using data recorded by 141 micro-electro mechanical system (MEMS)-based with...

The current study aims to investigate damage assessment of the RC frames with brick masonry infill (BMI). effects near-source ground motions (GMs) are considerably predominant in seismic response structure as related far-source motion due their forward directivity plus long period. is characterized by enormous everlasting translation, strong peak acceleration (PGA), and a very low-frequency pul...

in this paper a simple model of a three story building with inclined first-story columns has presented. the stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational dampers. the considered model is subjected to horizontal component of fault normal pulse with different magnitudes and the governed nonlinear di...
