Seismic isolation of cable‐stayed bridges for near‐field ground motions
Earthquake Engineering & Structural Dynamics, 2003AbstractThis study examines the efficacy of using seismic isolation to favorably influence the seismic response of cable‐stayed bridges subjected to near‐field earthquake ground motions. In near‐field earthquake ground motions, large amplitude spectral accelerations can occur at long periods where many cable‐stayed bridges have significant structural ...

Near-field ground motion and dynamic rupture process
2023In order to realise the comprehensible simulations of dynamic rupture process and wave propagation, it is important to take into account of fault geometry, strses field and frictional property. Although it is always a difficult task to guess all the factors before an earthquake, there have been a lot of efforts to determine the model parameters for the

Response of buildings to near-field pulse-like ground motions
Earthquake Engineering & Structural Dynamics, 1999Ground motions affected by directivity focusing at near-field stations contain distinct pulses in acceleration, velocity, and displacement histories. For the same Peak Ground Acceleration (PGA) and duration of shaking, ground motions with directivity pulses can generate much higher base shears, inter-storey drifts, and roof displacements in high-rise ...

Reliability analysis of braced frames subjected to near field ground motions
Earthquakes and Structures, 2013Near field ground motions have caused several structural damages in recent decades. As a result, seismic codes are being updated with related requirements. In this paper a comparative study on the seismic behavior of concentrically braced frames (CBFs) designed based on different seismic codes is performed.

GENERATION OF UNIFORM HAZARD EARTHQUAKE ACCELEROGRAMS AND NEAR-FIELD GROUND MOTIONS
Journal of Earthquake and Tsunami, 2012The sets of records developed for the SAC Steel Project are classified according to the level of seismic hazard and specific geographic region, and have been used extensively for structural response and seismic hazard analyses. This study presents a parametric analysis of these record data sets for generation of uniform hazard earthquake and near-field

On the response of r.c. buildings to near-field ground motions
2015This paper shows the results of a nonlinear dynamic analysis of a fixed base reinforced concrete 2D frame subjected to near-field earthquakes, i.e. seismic motions recorded close to the epicentral area of the fault rupture. In these areas both the acceleration and velocity signals are impulsive and consequently the response of the structures requires a
