abstract: Due to the paucity of studies regarding seismic assessment buildings in Brazil, this study aims present and discuss a reliability reinforced concrete framed structure designed according Brazilian standard ABNT NBR 6118:2014 without consideration design requirements 15421:2006. Herein, fragility functions are generated through probabilistic demand analysis, integrated with hazard curve...

In the event of a black hole (BH) forming stellar collapse, neutrino signal should terminate abruptly at moment BH formation, after phase steady accretion. Since neutrinos are expected to reach Earth hours before electromagnetic signal, combined detection burst through multiple telescopes could allow promptly determine angular location nearby collapse in sky with high precision. this paper, we ...

Aftershock fragility is usually calculated conditioned on a range of potential post-mainshock damage states. The can be identified using indices, the latter being frequently associated with displacement-based parameters such as maximum drift ratio or residual displacement. However, when reliable simulation structural system in specific state objective numerical study, indicators may not assure ...

Shock-induced collapse of nanobubbles in water is investigated with molecular dynamics simulations based on a reactive force field. We observe a focused jet at the onset of bubble shrinkage and a secondary shock wave upon bubble collapse. The jet length scales linearly with the nanobubble radius, as observed in experiments on micron-to-millimeter size bubbles. Shock induces dramatic structural ...

The present work summarises a numerical procedure aimed to the residual strength assessment of a cracked butt joint, based on R-curve analysis and plastic collapse prediction. In a linear elastic fracture analysis, the SIF’s (Stress Intensity Factors) evaluation is based on the use of the Dual Boundary Element Method, as implemented in the BEASY code. A two -dimensional approximation (plane str...

[1] The probability density function of the drop diameter at the ground is investigated during stratiform and convective precipitation intervals at Darwin, Australia. We show how, after a renormalization procedure of the drop diameter, the empirical probability density functions of both types of precipitation collapse in a single curve, indicating the possible existence of an invariant distribu...

To accurately predict the seismic demands of structural systems, a proper set ground motions representing hazard given site is needed. In general, such includes large number motions, and thus may result in high computational cost. address this challenge without compromising accuracy fragility, paper proposes clustering-based algorithm that can select representative subset adaptively from motion...

Fragility curves are a common tool to appraise the expected damage critical infrastructure (CI) after an earthquake event. Previous studies offer fragility curve parameters for CI that suitable vast range of systems, without in-depth examination system architecture and subcomponents. These applicable in cases where thorough analysis is not required or when information related single poor. This ...

The forced rupture of single chemical bonds in biomolecular compounds (e.g. ligand-receptor systems) as observed in dynamic force spectroscopy experiments is addressed. Under the assumption that the probability of bond rupture depends only on the instantaneously acting force, a data collapse onto a single master curve is predicted. For rupture data obtained experimentally by dynamic AFM force s...
