Dynamic soil-structure interaction (DSSI) plays a fundamental role in many geotechnical and/or structural design situations,
as clearly shown by the damage which occurred during several recent earthquakes (Kobe 1995; Koaceli 1999; Chi-Chi 1999; L’Aquila
2009). For a long time civil engineering researchers have devoted increasing attention to this subject. Thanks to their efforts,
several technical regulations, such as EC8 (2003), have taken DSSI into account. However, many steps are still necessary in order to increase our knowledge regarding this
complex phenomenon, as well as to make all the results achieved known to academics and practitioners. This paper presents
the results of a shaking table test performed on a scaled physical model consisting of a 3-D steel frame resting on a bed
of sand. The experimental results are compared with the numerical ones obtained using a sophisticated elasto-plastic constitutive
model recently implemented in the FEM code utilised. The solution of geotechnical problems requires the use of appropriate
constitutive models. Many interesting constitutive models have been developed, but only a few of these have been implemented
into commercial numerical codes; which is particularly so when dynamic analyses are required. The described experimental results,
as well as the comparison between them and the numerical results, allow interesting considerations to be drawn on dynamic
soil-structure interaction and on its numerical simulation. 相似文献

Currently, 18 impact structures have been identified on the continent of Africa. No impact structures are so far known in
Ethiopia, with the exception of a suggestion of an impact crater centered on the town of Shakiso, southern Ethiopia. Our field
work, petrographic, and geochemical studies on rocks from the area do not show any evidence of an impact structure at that
locality.

Settlement analysis of field cases is normally studied based on parameters interpreted from laboratory samples influenced by varying degrees of sample disturbance. Such disturbance is more pronounced in natural soft clays and could significantly affect the engineering properties of the soil, e.g. the over consolidation ratio (OCR) and compressibility index (Cc). Hence, it is vital to understand the role of sample quality in relation to soil characterisation for long-term settlement analyses. In this work, this is numerically illustrated by use of a simple creep model along with realistic parameter selection. This work takes its starting point on critical discussion of the work presented by Fatahi et al. (2013) and uses the opportunity to further clarify some important aspects of settlement/creep analyses in light of sample quality and parameter interpretation valid for the corresponding constitutive model. 相似文献
