Seismic Performance Evaluation and Retrofit of Existing School Buildings (CROCS-System) in Switzerland

Existing school buildings in Switzerland that have been designed from the early 1970s typically utilized a modular architectural layout and structural system commonly known as CROCS (Centre de rationalization de d’organisation des constructions scolaires). ...

Spectral shape metrics and structural collapse potential

Dimitrios Lignos

This paper examines various parameters that provide a measure of spectral shape and studies how they relateto the potential of ground motion records to cause the collapse of a given structure. It is shown that whenmeasuring the ground motion intensity by t ...

Seismic vulnerability assessment at urban scale for two typical Swiss cities using Risk-UE methodology

Pierino Lestuzzi, Angelo Garofano, Stefano Podesta, Patrick Bischof

This paper contains a seismic assessment at urban scale of the cities of Sion and Martigny in Switzerland. These two cities have been identified for the present research based on their importance regarding size and the characteristics of the building stock ...

Seismic assessment of a historical masonry building in Switzerland: the “Ancien Hôpital de Sion”

Pierino Lestuzzi, Angelo Garofano

The paper presents the results of the evaluation of the seismic safety of the Ancien Hôpital de Sion, an important Swiss architectural heritage building, sited in the Canton of Valais, the region with the highest seismic hazard in Switzerland. Three-dimens ...

Wide-field medium-repetition-rate multiphoton microscopy reduces photodamage of living cells

Sylvie Roke, Carlos Alberto Macias Romero, Siyuan Wang, Vitalijs Zubkovs

Demands of higher spatial and temporal resolutions in linear and nonlinear imaging keep pushing the limits of optical microscopy. We showed recently that a multiphoton microscope with 200 kHz repetition rate and wide-field illumination has a 2–3 orders of ...

Displacement-based seismic design of symmetric single-storey wood-frame buildings with the aid of the N2 method

Katrin Beyer, Panagiotis Mergos

This paper presents a new methodology for the displacement-based seismic design of symmetric single-storey wood-frame buildings. Previous displacement-based design efforts were based on the direct displacement-based design approach, which uses a substitute ...

Design Decision Support for Steel Frame Buildings through an Earthquake-Induced Loss Assessment

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Seong-Hoon Hwang

In recent years, there is an increasing need to quantify earthquake-induced losses throughout the expected life of a building in order to evaluate alternative design options such that we can minimize repairs in the aftermath of an earthquake. This paper di ...

Sensitivity of drift capacities of URM walls to cumulative damage demands and implications on loading protocols for quasi-static cyclic tests

Katrin Beyer, Panagiotis Mergos

Displacement-based seismic design and assessment procedures require as key input parameter estimates of displacement capacities of the critical elements. The displacement capacities of unreinforced masonry (URM) walls are typically determined by means of q ...

Evaluating seismic retrofitting efficiency through ambient vibration tests and analytical models

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Angelo Garofano

Economic and environmental imperatives lead to an ever growing need to extend the service life of the existing building stock without putting the users at risk. In zones prone to moderate seismic hazard, many buildings were built without considering seismi ...

Evaluating snow weak-layer failure parameters through inverse finite element modelling of shaking-platform experiments

Johan Alexandre Philippe Gaume

Snowpack weak layers may fail due to excess stresses of various natures, caused by snowfall, skiers, explosions or strong ground motion due to earthquakes, and lead to snow avalanches. This research presents a numerical model describing the failure of "san ...
