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...

To rank the pulse-like ground motions based on damage potential to different structures, internal relationship between of and engineering demand parameters (EDPs) is analyzed in this paper. First, a total 240 from NGA-West2 database 16 intensity measures (IMs) are selected. Moreover, four reinforced concrete frame structures with significantly natural vibration periods established for dynamic a...

The response of structures under pulse-like ground motions is characterized by the large amount energy input in a few cycles. Consequently, with insufficient strength may suffer severe damage owing to excessive deformation. In previous paper, energy-based prediction procedure for peak and cumulative reinforced concrete (RC) frame building steel damper columns was proposed (Fujii Shioda, Buildin...
