The test results obtained for reinforced concrete columns by several studies have revealed that the peak displacement and cumulative hysteresis energy are important parameters evaluating damage of under horizontal bidirectional unidirectional loading. Therefore, seismic related to nonlinear with regard input should be investigated. In this study, an isotropic one-mass two-degree-of-freedom syst...

Ground motion estimation for a site (34.01 o N, 71.45 o E) located in the Peshawar in terms of Peak Ground Acceleration (PGA) values is conducted. It is carried out with deterministic seismic hazard analysis approach using faults sources within a radius of one hundred kilometers around site. The results of this study indicate that the Main Boundary Thrust located at a distance of twenty nine (2...

Reinforced concrete frame buildings with Open Ground Story (OGS) are one of the most common building configurations in urban habitat. These configurations are known to be vulnerable to seismic excitations, primarily due to the sudden loss in strength in the ground story and differential stiffness distribution throughout the structure. The differential stiffness distribution is attributed primar...

The Wenchuan earthquake of 12 May 2008 is the most destructive earthquake in China in the past 30 years in terms of property damage and human losses. In order to understand the earthquake process and the geo-morphological factors affecting the seismic hazard, we simulated the strong ground motion caused by the earthquake, incorporating three-dimensional (3D) earth structure, finite-fault ruptur...

Ground-motion models have gained foremost attention during recent years for being capable of predicting ground-motion intensity levels future seismic scenarios. They are a key element estimating hazard and always demand timely refinement in order to improve the reliability maps. In present study, we propose ground motion prediction model induced earthquakes recorded The Geysers geothermal area....

We propose a new algorithm to rapidly determine earthquake source and ground-motion parameters for earthquake early warning (EEW). This algorithm uses the acceleration, velocity, and displacement waveforms of a single three-component broadband (BB) or strong-motion (SM) sensor to perform real-time earthquake/noise discrimination and near/far source classification. When an earthquake is detected...

The purpose of this study was to investigate the ground reaction force and kinematic variables in the ballet single turn called pirouette in both flat shoes and pointe shoes by skilled professional ballet dancers. Kinematic parameters of both legs and ground reaction force were obtained from eight skilled ballet dancers through a threedimensional motion analysis. We found significant increased ...
