Loading protocols for European regions of low to moderate seismicity

Existing loading protocols for quasi-static cyclic testing of structures are based on recordings from regions of high seismicity. For regions of low to moderate seismicity they overestimate imposed cumulative damage demands. Since structural capacities are ...

Parallel preconditioners for the unsteady Navier-Stokes equations and applications to hemodynamics simulations

Alfio Quarteroni, Simone Deparis, Gwenol Grandperrin

We are interested in the numerical solution of the unsteady Navier-Stokes equations on large scale parallel architectures. We consider efficient preconditioners, such as the Pressure Convection-Diffusion (PCD), the Yosida preconditioner, the SIMPLE precond ...

Human convective boundary layer and its interaction with room ventilation flow

Dusan Licina

This study investigates the interaction between the human convective boundary layer (CBL) and uniform airflow with different velocity and from different directions. Human body is resembled by a thermal manikin with complex body shape and surface temperatur ...

Experimental investigation of the human convective boundary layer in a quiescent indoor environment

Dusan Licina

This study aims to characterize human convective boundary layer (CBL) in a quiescent indoor environment. The study has two objectives: first, to characterize the velocity field around the thermal manikin under two ambient temperatures and body postures; an ...

Damage predicting algorithms for regular RC structures

Pierino Lestuzzi, Amin Karbassi

In this paper a 2-phase decision tree algorithm is developed to qualitatively predict damage in RC buildings based on earthquake characteristics and structural properties. To this end, the structural properties considered are the natural period of the fund ...

Fling-step effect on the seismic behavior of high-rise RC buildings during the Christchurch earthquake

Pierino Lestuzzi, Amin Karbassi

Fling-step and forward directivity, which can impose unexpected seismic demands on structures, are the main consequences of near-fault earthquakes. Although the adverse effect of forward directivity on structures behavior is determined to some level, the i ...

Coupled seismogenic geohazards in Alpine regions

Lyesse Laloui, Pierino Lestuzzi, Alessio Ferrari, Cyrill Silvan Baumann, Clotaire Michel, Fabrice Dupray, Amin Karbassi

COupled seismogenic GEohazards in Alpine Regions (COGEAR) is an interdisciplinary natural hazard project investigating the hazard chain induced by earthquakes. It addresses tectonic processes and the related variability of seismicity in space and time, ear ...

Dynamics of Slip Fronts at Frictional Interfaces: Analysis of Slip Precursors and Rupture Velocity

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer, Vladislav Yastrebov

The rupture dynamics of earthquakes span a considerable range, from slow to super-shear ruptures. Rupture speed has a major influence on the generation of strong ground motions, yet our understanding of the mechanisms causing these variations in the ruptur ...

Fragility Analysis of Existing Unreinforced Masonry Buildings through a Numerical-based Methodology

Pierino Lestuzzi, Amin Karbassi

As an approach to the problem of seismic vulnerability evaluation of existing buildings using the predicted vulnerability method, numerical models can be applied to define fragility curves of typical buildings which represent building classes. These curves ...

Cyclic demand at the shell-bottom connection of unanchored steel tanks

Alain Nussbaumer, Gary Scott Prinz, Gustavo Cortes

Gasoline and other oil byproducts are commonly stored in steel tanks that rest on ground without any anchorage. Under strong motion, the impulsive mass of the contained liquid generates a moment about the base of the tank capable of causing partial uplift ...
