A seismological overview of long-period ground motion

Journal of Seismology, 2008
Long-period ground motion has become an increasingly important consideration because of the recent rapid increase in the number of large-scale structures, such as high-rise buildings and oil storage tanks. Large subduction-zone earthquakes and moderate to large crustal earthquakes can generate far-source long-period ground motions in distant ...

Measures for the Long-Period Ground Motion

2019
Long-period earthquake ground motion greatly affects earthquake resistance of skyscrapers, so it is necessary to create long-period ground motion for use in its dynamic design. This chapter describes concretely how to create long-period ground motion caused by a huge earthquake that is thought to occur in the near future in Japan by means of ...

Optimal ground motion intensity measure for long-period structures

Measurement Science and Technology, 2015
This paper aims to select the most appropriate ground motion intensity measure (IM) that is used in selecting earthquake records for the dynamic time history analysis of long-period structures. For this purpose, six reinforced concrete frame-core wall structures, designed according to modern seismic codes, are studied through dynamic time history ...

Multicomponent C3 Green’s Functions for Improved Long‐Period Ground‐Motion Prediction

Bulletin of the Seismological Society of America, 2017
The virtual earthquake approach to ground-motion prediction uses Green’s functions (GFs) determined from the ambient seismic field to predict long-period shaking from scenario earthquakes. The method requires accurate relative GF amplitudes between stations and among components; however, the amplitudes of ambient-field GFs are known to be subject to ...

Long-period ground motion in the epicentral area of major earthquakes

Tectonophysics, 1974
In view of the potential importance of long-period ground motion in the design of large structures, near-field ground displacement is computed by the elastic dislocation theory for several earthquake fault models. The validity of such computations is confirmed by comparing the computed seismogram with the observed long-period seismogram of the 1923 ...

Conditions that give rise to unusually large long period ground motions

The Structural Design of Tall Buildings, 1993
AbstractSeveral ground motion conditions that are of little concern for conventional structures can be quite important for structures having natural periods longer than 1 s. Firstly, a large long‐period pulse of motion, due to the effect of rupture propagation (directivity), is observed in the direction normal to the fault at strong motion stations ...
