Studies on the seismic response of skewed integral abutment bridges have mainly focused under far-field non-pulse-type ground motions, yet large amplitude and long-period velocity pulses in near-fault motions might significant impacts bridge response. In this study, nonlinear dynamic an (SIAB) pulse far-fault non-pulse type are analyzed considering soil–structure interaction, along with paramet...

A base-isolated building may sometimes exhibit an undesirable large response to a long-duration, long-period earthquake ground motion and a connected building system without base-isolation may show a large response to a near-fault (rather high-frequency) earthquake ground motion. To overcome both deficiencies, a new hybrid control system of base-isolation and building-connection is proposed and...

Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...

Performance based design (PBD) is an iterative exercise in which a preliminary trial design of the building structure is selected and if the selected trial design of the building structure does not conform to the desired performance objective, the trial design is revised. In this context, development of a fundamental approach for performance based seismic design of masonry infilled frames with ...

Recent studies emphasize the rapid assessment of earthquake source properties, such as moment magnitude, to help alleviate the impact of earthquakes. Depending on local crustal structure, earthquakes occurring at different depths can differ greatly in high-frequency motions, which emphasizes the importance in constraining focal depth for the predictions of strong motions. For large earthquakes,...

Abstract We study how the asymmetric geometry of thrust faults affects dynamics supershear ruptures and their associated trailing Rayleigh as they interact with free surface, investigate resulting near‐field ground motions. Earthquakes are mimicked by propagating laboratory along a frictional interface 61° dip angle. Using an experimental technique that combines ultrahigh‐speed photography digi...
