During an earthquake, part of the released elastic strain energy is dissipated within the slip zone by frictional and fracturing processes, the rest being radiated away via elastic waves. While frictional heating plays a key role in the energy budget of ea ...
Seismic response of joints which are found to be ubiquitous in rock masses is of great interest to rock engineers, geophysicists and seismologists. In the past years, wave propagation across rock joints has been the subject of extensive theoretical and exp ...
Steel lateral load-resisting systems offer a variety of design solutions to ensure a ductile behaviour of a structure during a seismic event, thereby achieving a relatively low earthquake-induced collapse risk, if designed and detailed properly according t ...

Code design of slab-column connections to resist seismically induced drifts is currently based on empirical relationships for both moment and deformation capacity. The results of tests on slab-column connections are however sensitive to the conception of t ...
A large part of ancient built environments in earthquake prone areas have been accomplished exclusively thanks to the experience that their builders developed over centuries of practice. Several of the resulting techniques have showed a satisfactory perfor ...
The concept of simultaneous source has recently become of interest in seismic exploration, due to its efficient or economic acquisition or both. The blended data overlapped between shot records are acquired in simultaneous source acquisition. Separating th ...
We present experimental observations of microjets formed by cavitation microbubbles. An underwater electric discharge, applied beneath a flat free surface, produces a primary compression wave, which undergoes several phase inversions upon reflections from ...
In this paper, we carry out a numerical dispersion analysis for the linear two-dimensional elastodynamics equations approximated by means of NURBS-based Isogeometric Analysis in the framework of the Galerkin method; specifically, we consider the analysis o ...
Mid- to high-rise buildings in seismic areas are often braced by slender reinforced concrete (RC) walls, which are interconnected by RC floor diaphragms. In design it is typically assumed that the lateral forces are distributed in proportion to the wall’s ...
Filling materials may exist in all scales of rock fractures, not only influencing seismic wave attenuation, but controlling rock mass instability. The objective of this study is to experimentally investigate the seismic response of rock fractures filled wi ...
