Simulations of Long-Period Ground Motions during the 1995 Hyogoken-Nanbu (Kobe) Earthquake using 3D Finite Element Method
Long-period strong motions (> 0.9 second) are simulated in the Kobe area for the mainshock (1/17/95) and the aftershock (2/2/95) of the Hyogoken-Nanbu (Kobe) earthquake. In order to model ground motions in the realistic and highly heterogeneous basin structure, an unstructured 3D FEM (Finite Element Method) is used, which runs efficiently on parallel computers. The simulation results show stron...

متن کاملReliability of Envelope Inversion for the High-Frequency Radiation Source Process Using Strong Motion Data: Example of the 1995 Hyogoken Nanbu Earthquake
This article presents an application of a procedure to invert the highfrequency radiation process at the source during the 1995 Hyogo-ken Nanbu earthquake using the envelopes of acceleration waveforms from 16 stations. The inversion uses genetic algorithms that compare observed ground motions with synthetic ones calculated using empirical Green’s functions. Before the inversion, the reliability...
متن کاملA Phenomenological Study on Inelastic Torsion Caused By Nonlinear Behavior Changes during Earthquake Excitations
Torsion of many symmetric structures, which were designed based on the seismic codes, is due to their asymmetricity induced during inelastic behavior. Although the structure was designed symmetrically assuming elastic based criteria, different factors such as material inconsistency in structure, construction details discrepancy and construction errors may result in asymmetric behavior in inelas...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
