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 buildin

During the great 2010, Chile earthquake, reinforced concrete (RC) buildings showed adequate performance. However, in some of them a particular damage pattern involving brittle failure of RC walls was observed in the lower stories, usually associated with

On April 1 st , 2014, the 8.2 M w Pisagua earthquake affected the population in the north of Chile and generated disruption of services in the region. The largest effects of the earthquake were observed in the city of Iquique, capital of the Tarapaca Regi

In a post-disaster environment, hospitals play a critical role in healthcare services continuities to the population while effectively coping with eventual losses of functionality. These losses come from physical damage to the facility, loss of utility li

Major earthquakes may require people to evacuate immediately from buildings due to other consequential hazards, e.g. fires, landslides, tsunamis, or significant structural damage. During the evacuation, building occupants are exposed to floor acceleration

This paper describes the reconnaissance work conducted by researchers from the National Research Center for Integrated Natural Disaster Management (CIGIDEN) between September 23 rd and October 2 nd in the area affected by the M w 8.3 Illapel megathrust ea

Chile is known as one of the most seismic countries in the world showing approximately one event above magnitude 8 every ten years. Unexpected damage occurred in reinforced concrete (RC) buildings during the 2010 Mw 8.8 Maule earthquake. Calculating the r

A general design procedure for elastic buildings equipped with linear and non-linear energy dissipating devices is presented herein. The procedure begins with an estimation of the total amount of equivalent damping and stiffness required to achieve a pred

The adequate performance of critical infrastructure such as transportation, telecommunications, healthcare, and electric power systems are essential to the resilience of communities after major earthquakes. However, assessing the seismic risk of networks

This study quantifies the epistemic uncertainty of several modeling assumptions in evaluating the seismic response of six reinforced concrete free-plan office buildings located in Santiago, Chile. The assumptions analyzed are: (1) the in-plane and out-of

A brittle damage pattern has been observed in some reinforced concrete (RC) shear wall buildings during recent earthquakes. Although substantial experimental and analytical research has been conducted, many questions remain about the inelastic behavior of

We analyzed the coseismic and early postseismic deformation of the 2015, M-w 8.3 Illapel earthquake by inverting 13 continuous GPS time series. The seismic rupture concentrated in a shallow (

Reinforced concrete shear wall buildings have shown, in statistical terms, an adequate performance in past seismic events. However, a specific damage pattern was observed in 2010 Chile earthquake in some shear walls located in the lower building stories

Este artículo resume la campaña experimental de nueve muros esbeltos de hormigón armado que se realizó durante 2013 en la Pontificia Universidad Católica de Chile. El objetivo principal de estos ensayos es comprender de mejor forma la falla frágil que se

This article describes some of the new trends observed in research and design of structures equipped with seismic protection systems (SPS). This field of earthquake engineering has almost 40 years of formal development and techniques have gained increasin

Hospitals are critical facilities that are essential for providing first-aid response to communities in the aftermath of disasters such as earthquakes. The seismic performance of these facilities is highly dependent on the structural behaviour and the vul

This research investigates the development of a semi-active piezoelectric friction damper for controlling the seismic response of large-scale structures. The proposed device is made of Duplex steel and leads to high friction capacity, which can be develop

Los edificios de planta libre son una tipología común en Chile y el mundo. En todos los casos, el diseño sísmico de estos edificios en la práctica se realiza usando modelos de elementos finitos de software comercial. El objetivo de esta investigación es e

Nonlinear dynamic analysis is becoming an accepted procedure to assess the performance of building structures during earthquakes. Several documents have emerged to provide guidance in terms of mathematical modeling, ground motion selection and scaling, an

This article summarizes statistical results of reinforced concrete (RC) wall buildings taller than 9 stories damaged during the February 27, Chile earthquake. This type of buildings suffered brittle damage localized in RC shear walls mainly in the lower s

At 3:34AM local time, on February 27 th , 2010, a moment magnitude Mw 8.8 megathrust earthquake struck offshore the coast of Chile. The earthquake ruptured a 540 by 200 km mature seismic gap of the underlying subduction pacific plate interlocking mechanis

This article deals with the development of a long-stroke MR-damper intended to control, by reacting on a tuned mass, the earthquake performance of an existing 21-story building located in Santiago, Chile. The ±1 m stroke MR-damper was designed using the n

Significant damage was observed in reinforced concrete walls of residential buildings following the 2010 Maule earthquake in Chile. The damage in structural walls was brittle and concentrated near the ground level. The most common observed damage in such

This article presents an overview of the different processes of data recollection and the analysis done by different stakeholders during and after the emergency caused by the 2010 Maule earthquake in central-south Chile. The article is not an exhaustive r
