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.
In the second half of the 20th century, the majority of residential buildings in Switzerland have been built with unreinforced brick masonry walls and reinforced concrete floors. Following a re-evaluation of the seismic hazard in Switzerland, a country of ...
Reinforced concrete slabs supported on columns fail by punching when a conical plug of concrete perforates the slab above the column. This failure has been mostly investigated experimentally, so what can numerical simulation contribute to understand this p ...
In unreinforced masonry (URM) walls the vertical piers are connected by horizontal spandrel elements. Numerical simulations have shown that spandrels influence significantly the global wall behaviour under seismic loading. Despite their importance, experim ...
Reinforced concrete being the most applied construction material today performs very well in most applications but still lacks durability under severe environmental conditions. Especially existing structures built decades ago show degradation. Using Ultra- ...
U-shaped or channel-shaped walls are frequently used as lateral strength providing members in reinforced concrete (RC) buildings since their form does not only provide strength and stiffness in any horizontal direction but is also well suited to accommodat ...
This thesis addresses the seismic evaluation of existing buildings. In particular, it focuses on the seismic behavior of lightly reinforced shear walls that are not designed to withstand earthquake actions. A shear strength envelope for the assessment of d ...
Structural elements combining Ultra-High Performance Fiber Reinforced Concretes (UHPFRC)and concrete offer a high potential in view of rehabilitation and modification of existing structures. The investigation of the time-dependent behavior of composite “UH ...
e numerical simulation of concrete dams subjected to earthquake loading requires realistic material laws which take into account seismic loading conditions. Dynamic tests were performed in order to examine the effect of initially applied compressive loadin ...
The numerical simulation of concrete dams subject to earthquake loading requires realistic material laws which take into account material properties as effected by seismic action. Experiments under simulated seismic action were performed to examine the eff ...
Buildings are very often horizontally stabilized by means of a core or by shear walls. Bridge girders are also often laterally restrained by a horizontal fixed support at the abutment. It follows that the columns of such systems are restrained against any ...
