Fragility functions are commonly used in performance-based earthquake engineering for predicting the damage state of a structure subjected to an earthquake. This process often involves estimating the structural damage as a function of structural response, ...
Seismic risk for cultural heritage buildings has been underestimated for years in Switzerland. A strong earthquake can occur at any time in this region, as it has been shown during the last centuries. As reminder the 1356 seismic event that destroyed the c ...
Seismic verification of existing buildings in Switzerland is currently assessed by the pre-standard 2018. In the seismic evaluation of existing buildings in that document, a minimal acceptable seismic safety must be verified, as well as proportional level ...
For earthquake protection of structures such as bridges, viaducts and embankments, a precise and safe dimensioning has to be calculated according to the soil profile, the location of potentially active faults and the local liquefaction risk, as they all in ...
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 ...
Fragility functions that permit the estimation of damage in pre-1994 welded flange bolted-web beam-to-column moment connections are developed. The fragility functions provide estimates of the probability of yielding and of experiencing fracture as a functi ...
In countries with a moderate seismic hazard, the classical methods developed for strong motion prone countries to estimate the seismic behaviour and subsequent vulnerability of existing buildings are often inadequate and not financially realistic. The main ...
Seismic wave propagation in granular soils can induce large strain amplitudes in case of strong earthquakes. Seismic motions are irregular in frequency content and in amplitude, and have three different components in orthogonal directions. In this context, ...
Elastic fundamental frequency is a key-parameter of simplified seismic design and vulnerability assessment methods. Empirical relationships exist in codes to estimate this frequency but they miss experimental data to validate them accounting for national f ...
AB: The accurate prediction of near-source strong-ground motions in future earthquakes is a major challenge for seismologists and earthquake engineers. Such a prediction is however difficult, partly because ground motions are highly variable while the reas ...
