Damage spectra for reinforced concrete buildings in Greece are presented in this paper based on a series of time-history nonlinear dynamic analyses for single-degree-of-freedom systems (Clough hysteresis model) with different deformation ductility and yiel ...
Like photonic crystals have revolutionized the way of manipulating optical waves at the sub-micron scale, phononic crystals have more recently played similar decisive role for sound waves, or more generally elastic waves. Then, the idea of coupling light a ...
Stochastic seismic wave interaction with a slippery rock fault is studied, based on the principle of conservation of momentum at the wave fronts along the fault. By using the displacement discontinuity method, the wave propagation equations are derived for ...
In many unreinforced masonry (URM) buildings reinforced concrete (RC) ring beams are introduced at each storey in order to maintain the integrity of the building when subjected to seismic loading. Such ring beams also contribute to the in-plane resistance ...
Remote sensing of fractures with elastic waves is important in fields ranging from seismology to nondestructive testing. In many geophysical applications, fractures control the flow of fluids such as water, hydrocarbons or magma. While previous analytic de ...
Unreinforced masonry (URM) walls comprise vertical piers and horizontal spandrels, which together form the lateral load resisting system. Whereas past research yielded significant advances in the understanding of the force-deformation characteristics of ma ...
When an unanchored tank is subjected to strong motion, the impulsive mass of the contained liquid generates a moment which if strong enough could cause partial uplifting of the base plate. As the tank undergoes uplifting, the shell-base welded connection i ...
Unanchored steel tanks subjected to strong ground motion may experience rocking motion if the moment generated by the inertial mass of the content stored is greater than the resisting moment provided by the weight of the tank and its content. Rocking of th ...
The in-plane component of the wavefield provides valuable information about media properties from seismology to nondestructive testing. A new compact scanning laser ultrasonic interferometer collects light scattered away from the angle of incidence to prov ...
The seismic assessment of existing buildings has been underestimated in regions with moderate seismic hazard, such as the North-West Europe. Strong earthquakes, such as the 1356 Basel earthquake, already occurred in such regions and caused severe damage. T ...
