Seismic response of various sites of the territory of Kyiv to seismic loads

open access: yesГеофизический журнал, 2021
The research presented in the work aims to assess the seismic response of three different taxonometric sites, identified by the method of engineering and geological analogies within the territory of Kyiv, to seismic loads with different spectral content

Regional Seismic Wavefield Propagation [PDF]

open access: yes, 2004
Through the examination of local and regional seismic waveform data the crust and upper mantle of southern California are investigated. Using local and regional seismic phases such as Pn, Sn, PL, and surface waves, seismic wave velocities of interesting

Seismic soil-structure interaction for pile supported systems [PDF]

open access: yes, 2009
Civil engineering structures involve structural elements with direct contact with ground. When the external actions, such as earthquakes, act on these systems, neither the structural displacements nor the ground displacements, are independent of each ...

Response reduction map for two-degree-of-freedom system with friction

open access: yesNihon Kikai Gakkai ronbunshu, 2014
This paper deals with the response reduction effect by friction under 2-dof system. The friction behaviour is effective for dissipating seismic energy.
