Based on an innovative high-speed railway simply supported bridge (HSRSSB) model, the potential influence of near-fault pulse-type ground motions HSRSSB is analyzed. Eighty-five original records such are imposed simulation model. The dynamic responses calculated, including girder displacement, rail pier bending moment, bearing deformation, and residual displacement. Linear regression analysis r...

Near-field pulse-type ground motions (NPGMs) are characterized by a high-energy pulse with large peak velocities and accelerations need further studies to confirm whether structures viscous dampers (VDs) still applicable effective for this type of motions. In article, the vibration reduction performance VDs under near-field earthquakes is investigated systematically. Displacement acceleration s...

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...

ASCE 7-16 has provided a comprehensive platform for the performance-based design of tall buildings. The core of the procedure is based on nonlinear response history analysis of the structure subjected to recorded or simulated ground motions. This study investigates consistency in the ASCE 7-16 requirements regarding the use of different types of ground motions. For this purpose performance of a...

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...

This paper aimed to determine the effects of a pulse signal near-fault ground motion on dynamic response gravity dams, including dam-reservoir-foundation interaction, using different reservoir modelling approaches such as Westergaard, Lagrange, and Euler. As case study, Sarıyar concrete dam located Sakarya River, 120 km northeast Ankara, was considered for investigating ground-motion responses....
