Seismic risk assessment of human evacuations in buildings

A. Poulos(1) , S. Castro(2) , J. C. De la Llera(3) , J. Mitrani-Reiser(4) Abstract Major earthquakes may require people to evacuate immediately from buildings as recently observed in the 2015 Mw 8.3 Illapel earthquake in Chile. The building may suffer damage, thus affecting the evacuation process. Perhaps due to its apparent complexity, this interaction […]

Joint use of remote sensing data and volunteered geographic information for exposure estimation: evidence from Valparaíso, Chile

Christian Geiß (1), Anne Schauß (1) (4), Torsten Riedlinger (1), Stefan Dech (1), Cecilia Zelaya (2), Nicolás Guzmán (2), Mathías A. Hube (3), Jamal Jokar Arsanjani (4), Hannes Taubenböck (1). Resumen: The impact of natural hazards on mankind has increased dramatically over the past decades. Global urbanization processes and increasing spatial concentrations of exposed elements induce natural hazard risk at a uniquely high level. To mitigate affiliated perils requires detailed knowledge about elements at […]

Slip distribution of the 2014 MW = 8.1 Pisagua, northern Chile, earthquake sequence estimated from coseismic fore-arc surface cracks

John P. Loveless (1), Chelsea P. Scott(2), Richard W. Allmendinger (2), Gabriel González (4) Resumen The 2014 MW = 8.1 Iquique (Pisagua), Chile earthquake sequence ruptured a segment of the Nazca-South America subduction zone that last hosted a great earthquake in 1877. The sequence opened >3,700 surface cracks in the fore arc of decameter-scale length and millimeter-to centimeter-scale aperture. We […]

Earthquake risk assessment of buildings accounting for human evacuation

Alan Poulos (1), Juan Carlos de la Llera (2), Judith Mitrani-Reiser (3) Resumen A primary goal of earthquake engineering is to protect society from the possible negative consequences of future earthquakes. Conventionally, this goal has been achieved indirectly by reducing seismic damage of the built environment through better building codes, or more comprehensibly, by minimizing seismic risk. […]

A regularized fiber element model for reinforced concrete shear walls

Jorge A. Vásquez 1, Juan C. de la Llera 1 y Matías A. Hube 1 Abstract Reinforced concrete shear walls are used because they provide high lateral stiffness and resistance to extreme seismic loads. However, with the increase in building height, these walls have become slenderer and hence responsible of carrying larger axial and shear loads. Because 2D/3D finite […]

Development of a long-stroke MR damper for a building with tuned masses

René Zemp1, Juan Carlos de la Llera2, Hernaldo Saldias1 and Felix Weber3   Abstract This article deals with the development of a long-stroke MR-damper aimed to control, by reacting on a tuned mass (TM), the earthquake performance of an existing 21-story office building located in Santiago, Chile. The ±1 m stroke MR-damper was designed using […]

Seismic response of retaining walls with cohesive backfill: Centrifuge model studies

Gabriel Candiaa, b, , , Roozbeh Geraili Mikolac, Nicholas Sitard   Abstract Observations from recent earthquakes show that retaining structures with non-liquefiable backfills perform extremely well; in fact, damage or failures related to seismic earth pressures are rare. The seismic response of a 6-m-high braced basement and a 6-m free-standing cantilever wall retaining a compacted low plasticity […]

Toward a Decolonial Turn in Resilience Thinking in Disasters: Example of the Mapuche from Southern Chile on the Frontlines and Faultlines

Devin G. Atallah1 Abstract Resilience thinking has moved into the forefront of global discourses on Disaster Risk Reduction (DRR) and emergency response and recovery. Social justice frameworks have long been part of resilience thinking, conceptualizing multifaceted disasters as caused by interplays between physical, psychological, and sociopolitical dynamics that disproportionately impact marginalized communities, particularly in the […]

Development of national and local exposure models of residential structures in Chile

Hernán Santa María1,2, Matías A. Hube1,2, Felipe Rivera2, Catalina Yepes-Estrada3, Jairo A. Valcárcel3 Abstract: Large-scale impacts from natural disasters suffered by society encourage researchers and public agencies to develop methods to evaluate, mitigate, respond, and recover from these events. A key aspect for the calculation of the potential earthquake losses is to properly describe the […]

Zonas de catástrofe por eventos hidrometeorológicos en Chile y aportes para un índice de riesgo climático

Cristián Henríquez2, Nicolle Aspee3 y Jorge Quense4 Abstract Se estima que el cambio en los patrones globales del clima así como su dinámica natural pueden ocasionar una alta incidencia en los fenómenos extremos y en consecuencia aumentar los niveles de riesgos. En este estudio se revisan los principales desastres climáticos e hidrometeorológicos que han afectado […]
