Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This paper proposes methodological developments for quantifying the impact of residual axial shortening of first-story steel columns on earthquake loss estimations in steel moment-resisting frame (MRF) buildings. A new formulation is proposed that accounts ...
Tectonic faults typically break in a single rupture mode within the range of styles from slow slip to dynamic earthquake failure. However, in increasingly well-documented instances, the same fault segment fails in both slow and fast modes within a short pe ...
This study was conducted under the supervision of Prof. Sumusu Kono in the Tokyo Institute of Technology (TIT) and Prof. Katrin Beyer from the Earthquake Engineering and Structural Dynamics (EESD) laboratory in the Swiss Federal Institute of Technology in ...
Concentrically Braced Frames (CBFs) built before the introduction of the capacity design concept do not usually meet modern seismic design requirements. They are vulnerable to seismic events and they could develop unpredictable failure mechanisms. An exist ...
This paper presents the results of a series of shake table tests carried out on a half-scale single-story unreinforced masonry building with asymmetric openings. First, the unretrofitted building is subjected to seven increasing steps of bidirectional seis ...
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 ...

Capacity-designed steel moment-resisting frames (MRFs) dissipate the seismic action through inelastic flexural yielding of protected zones located at the beam ends and the first story column bottom end. During low-probability of occurrence seismic events, ...
During reservoir stimulations, the injection of fluids with variable viscosities can trigger seismicity. Several fault lubrication mechanisms have been invoked to explain the dynamic stress drop occurring during those seismic events. Here, we perform a par ...
Large-scale seismic risk assessment requires knowledge of the vulnerability of buildings. Under the action of an earthquake, buildings with different properties also behave differently. Since it is not possible to analyze each building individually, it is ...
Shape memory alloys (SMAs) have gained considerable attention in a broad range of engineering applications. In particular, iron-based SMAs (Fe-SMAs) have been recently developed and used as a cost-effective method for prestressed-strengthening of civil stru ...
