A Framework to Evaluate the Benefit of Seismic Upgrading

The framework to evaluate the benefit of seismic upgrading of Galanis et al. (2018) is compared to that present in the Swiss seismic code for existing buildings since 2004, updated in 2017. To illustrate the comparison, the example building of Galanis et a ...

Probabilistische Schadens-szenarien für den Kanton Basel-Stadt

Pierino Lestuzzi, Christine Tobler, Clotaire Michel

Dieser Beitrag präsentiert die Berechnung und Ergebnisse von drei Schadensszenarien für den Kanton Basel-Stadt. Bei der Berechnung wurden vorhandene Modelle für die Analyse der Bodenbewegungen und der Gebäudeverletzbarkeit mit einem probabilistischen Ansat ...

Einfluss des Einsatzes von Deckenscheiben aus Stahlbeton bei Mauerwerksgebäuden mit Holzbalkendecken bezüglich Erdbebensicherheit

Pierino Lestuzzi, Clotaire Michel, Lorenzo Diana

Ein Grossteil der Todesopfer und Gebäudeschäden bei stärkeren Erdbebenereignissen weltweit ist aufden Einsturz von Mauerwerksgebäuden zurückzuführen. Dieser ist oft Folge eines Versagens der (tragenden und sekundären) Mauerwerkswände quer zu ihrer Ebene. B ...

Evaluation of the seismic retrofitting of an unreinforced masonry building using numerical modeling and ambient vibration measurements

Pierino Lestuzzi, Clotaire Michel, Amin Karbassi

Ambient vibration measurements and 3-D nonlinear time-history numerical modeling are used to assess the retrofitting measures conducted in a 6-story unreinforced masonry building (URM) built in the end of the 19th century in Switzerland. Retrofitting measu ...

Deriving fragility functions from bilinearized capacity curves for earthquake scenario modelling using the conditional spectrum

Pierino Lestuzzi, Clotaire Michel, Pia Hannewald

The development of fragility curves to perform seismic scenario-based risk assessment requires a fully probabilistic procedure in order to account for uncertainties at each step of the computation. This is especially true when developing fragility curves c ...

Quantifying the Effects of Modeling Simplifications for Structural Identification of Bridges

Ian Smith, Marie Texier, Clotaire Michel, James-Alexandre Goulet

Several long-span, prestressed, segmental box girder bridges were built in the early 1980s and many of them are affected by long-term residual deformations. Although some models have been proposed to describe their structural behavior, several uncertaintie ...

Simplified non-linear seismic displacement demand prediction for low period structures

Pierino Lestuzzi, Clotaire Michel

The prediction of non-linear seismic demand using linear elastic behavior for the determination of peak non-linear response is widely used for seismic design as well as for vulnerability assessment. Existing methods use either linear response based on init ...

Hybrid probabilities and error-domain structural identification using ambient vibration monitoring

Ian Smith, Clotaire Michel, James-Alexandre Goulet

For the assessment of structural behaviour, many approaches are available to compare model predictions with measurements. However, few approaches include uncertainties along with dependencies associated with models and observations. In this paper, an error ...

Coupled seismogenic geohazards in Alpine regions

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

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 ...

Seismic vulnerability assessment to slight damage based on experimental modal parameters

Clotaire Michel

The aim of this paper is to adjust behaviour models for each class of structure for vulnerability assessment by using ambient vibration. A simple model based on frequencies, mode shapes and damping, taken from ambient vibrations, allows computation of the ...

Quantification of fundamental frequency drop for unreinforced masonry buildings from dynamic tests

Pierino Lestuzzi, Clotaire Michel

The knowledge of fundamental frequency and damping ratio of structures is of uppermost importance in earthquake engineering, especially to estimate the seismic demand. However, elastic and plastic frequency drops and damping variations make their estimatio ...
