The authors have proposed a new testing method for obtaining appropriate parameters of deformation characteristics of soils necessary for time-domain nonlinear seismic gr [...]

The 1999 Kocaeli earthquake in Turkey and the 1999 Chi-Chi earthquake in Taiwan indicated the horror of surface fault displacement. Regarding the surface fault displaceme [...]

This paper proposes a simple method to evaluate surface ground waveforms using both the natural period of the ground and input earthquake motion. In this research, the "E [...]

Past studies have shown that the input loss effect associated with the dynamic interaction of groundfoundation systems can be reproduced in large-scale group-pile foundat [...]

In Japan, after the 2011 Tohoku Earthquake and Tsunami, importance for the preparation for the situation beyond what was assumed in the design process is widely recognize [...]

In light of the serious tsunami disaster during the 2011 Tohoku earthquake and the subsequent severe accident at the Fukushima-Daiichi Nuclear Power Plant, the preparedne [...]

Damping properties are important in evaluating the safety of structures or the running safety of railway vehicles during earthquakes. For instance, it is pointed out that [...]

The design earthquake motions are often defined by the response spectra. For example, in the seismic design standard for the Japanese Railway facilities (1999) there are [...]

It is well known that the strength of reinforced concrete columns is degraded by cyclic loading, particularly in the post-peak region. When we examine the seismic safety [...]

It is well known that the non-stationary nature of earthquake motion is intensely controlled by the phase spectrum. However, it has not yet been verified how the stochast [...]
