Extreme Hydrodynamic impact onto buildings

The catastrophic tsunami events in 2004 and 2011 revealed that buildings with large openings often resisted better to the hydrodynamic impact of the wave. The steel or concrete structure of the building remained intact and the upper floors could serve as s ...

Nonmodel-based framework for rapid seismic risk and loss assessment of instrumented steel buildings

Dimitrios Lignos, Seong-Hoon Hwang

This paper proposes a nonmodel-based framework for estimating story-based engineering demand parameters (EDPs) in instrumented steel frame buildings with steel moment-resisting frames (MRFs). The proposed framework utilizes a wavelet-based damage-sensitive ...

Mapping seismic vulnerability at urban scale for disaster risk reduction

Yves Sylvain Gilles Reuland, Lorenzo Diana

Earthquakes do not kill people, buildings do. Transforming existing cities in earthquake resilient systems should be the main goal for researchers in the field of the seismic analysis of entire towns. Providing means for realistic disaster risk scenario ca ...

Seismic Performance Evaluation and Retrofit of Existing Steel Frame Buildings

Existing steel frame buildings in Switzerland that have been designed from the early 1970s typically utilized a steel lateral load resisting system with practically no seis- mic design requirements. However, Switzerland is a moderate seismicity zone and th ...

Structural Resilience through Model-Based Data Interpretation: From Building to City-Scale Post-Seismic Assessment

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

Earthquake-design approaches in regions with low to medium seismic hazard often focus on the protection of inhabitants. Therefore, some structural damage is accepted. In addition, large parts of the building stock have usually been built without considerin ...

Influence of building orientation on the hydrodynamic impact of water waves on buildings with openings

Claudia Ylla Arbos

Tsunamis, dam-break waves and impulse waves are catastrophic phenomena that leave thousands of victims and cause severe infrastructural damage. Understanding the impact that these waves have on structures is therefore necessary to properly dimension buildi ...

Estimation of wave propagation velocity on a channel with smooth and rough bed

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Natural hazards such as tsunamis, impulse waves and dam-break waves are rare, but extremely destructive. In recent times, more importance was given to structures that could withstand such events, however, uncertainties still exist in the estimation of wave ...

Earthquake-induced floor accelerations in base isolated structure

David Michael Volpe Ruggiero

In order to meet desired seismic performances, it is increasingly evident that engineers require reliable methods for the estimation of seismic demands on both structural and non-structural elements. To this end, current design codes incorporate simplified ...

Seismic vulnerability assessment of “Sion cathedral” (Switzerland): an integrated approach to detect and evaluate local collapse mechanisms in heritage buildings

Pierino Lestuzzi, Yves Sylvain Gilles Reuland, Lorenzo Diana

Seismic assessment of existing heritage buildings remains a challenging task. There is a high level of complexity and uncertainty compared with the assessment of standard buildings. Heritage masonry churches are usually prone to partial collapses during ea ...

Example of wave impact on a residential house

Anton Schleiss, Michael Pfister, Davide Wüthrich

Waves impacting against structures can create damages and devastation. This topic regained interest after some recent catastrophic events and the present paper investigates the main phases of a wave impacting against a residential house commonly observed i ...
