Integration of High-Rate GNSS and Strong Motion Record Based on Sage–Husa Kalman Filter with Adaptive Estimation of Strong Motion Acceleration Noise Uncertainty

Remote Sensing
A strong motion seismometer is a kind of inertial sensor, and it can record middle- to high-frequency ground accelerations. The double-integration from acceleration to displacement amplifies errors caused by tilt, rotation, hysteresis, non-linear ...

The Effect of strong motion duration on pounding of steel moment frame building [PDF]

Journal of Structural and Construction Engineering, 2019
Usually during moderate and strong earthquakes, if the space between the adjacent structures is not enough, structural pounding will occur which is due to the out-of-phase vibration of the structures regarding the differences in dynamic properties of the

Analysis on site effect of ground motion in Beijing urban area revealed by strong-motion records in M5.1 Guye，Tangshan earthquake on 12th July，2020

地震科学进展, 2020
Ground motion characteristics are significantly affected by local site conditions，as spectral acceleraiongs at medium-to-long periods would be obviously amplified on thick and soft sites as a result of seismic site effects.
