FONDAP 15110017. CIGIDEN. CIGIDEN is a FONDAP-CONICYT center of excellence which aims to generate knowledge of excellence to prevent extreme natural events from becoming disasters. To create knowledge and prevent extreme natural events from becoming disasters, CIGIDEN has a team of researchers from different fields, such as earth sciences, engineering, social sciences, geography, economics, design, architecture, urbanism and communications. This interdisciplinary approach led to a deep academic transformation, going from the study of natural hazards and emergency response, towards a comprehensive approach focused on reducing exposure to hazards and building resilience.

FONDECYT 3170867. Modeling the impact of natural hazards on complex interdependent systems using multilayer networks and graphical models. This project studies how disruptions propagate across interdependent systems from the standpoint of network science and knowledge discovery, using the region of Valparaíso in Chile as the system of study. Using analytical and statistical methods, this research seeks to derive analytical expressions that relate outcomes of the disruptions, say number of vertices reached by the cascade or other network indicators, to the characteristics of the system under study, i.e., statistics of its topology, and the initial damage caused by the natural hazard. This research also seeks to develop succinct descriptions of the most common pathways that disruptions take to propagate across systems and what consequences they have in terms of damage, affected people, downtime, etc, by using graphical models, such as Bayesian networks and hidden Markov models.

FONDECYT 11180937. Seismic Risk of Mined Tunnels. Urban tunnels are an important component of modern transport systems and transport millions of people daily. For this reason, it is essential that its design incorporates the effects of a severe seismic event and that it meets serviceability and life safety criterion. In general, the tunnels suffer lower levels of damage than surface structures, however, recent earthquakes (e.g., Niigataken-Chuetsu 2004, or Düzce 1999) have caused considerable structural damage. Due to the uncertainty that persists in the evaluation of the seismic response of tunnels, and in light of the latest experimental studies, this research aims to develop fragility and risk curves, providing relevant information to decision makers about the seismic response of tunnels. This research incorporates the state of the art in the calculation of seismic risk, compatible with performance-based design approach. You can contact to Dr. Candia for more information here.

FONDECYT 11170549. Natural Hazard Triggering Technological Disasters in Urban Zones. Hazmat release accidents from hazardous institutions and during hazmat transportation are attributed to a variety of causes, such as defective equipment, damaged materials, or operator and driver error. However, there are other sources that may trigger hazmat release, such as natural disasters. These events, known as “Natech” (Natural Hazard Triggering Technological Disasters), involve the release of a hazardous material as a result of a natural disaster, such as a hurricane or earthquake. Concern regarding Natech in densely-populated and industrialized areas, and the study of such phenomena, has increased strongly in the last decade. These events present characteristics that differentiate them from other types of hazmat release accidents: (i) many hazardous facilities and shipments may be affected simultaneously in the area affected by the natural disaster, easily exceeding the available response capacity; (ii) cascading disasters may occur (domino effects), in which the release of an active hazardous material triggers another; (iii) response staff and equipment may not be available; (iv) the damage to physical infrastructure resulting from the natural disaster may delay the response and aggravate its impacts. These characteristics are not currently considered in the literature on hazmat logistics when defining mitigation and response policies to tackle technological disasters. This background supports the need to develop methodologies for Natech mitigation, and to improve the response in the face of such events, considering their specific characteristics, which have not been considered in the literature. Thus, decisions on the (a) hazardous facility location-routing problem, (b) assessment of the vulnerability of the configuration of hazardous facilities location and the network of hazardous roads to implement protection measures, and (c) emergency response team location to mitigate Natech events, must be addressed. These are the topics that we propose to study in this project. You can contact to Dr. Bronfman for more information here.

FONDECYT 11170514. Vulnerability Analysis and Damage Control of Reinforced Concrete Wall Buildings. The behavior of reinforced concrete (RC) buildings during recent earthquakes around the world has shown adequate seismic performance by means of protecting human lives and preventing collapse. However, significant damage has been observed and there is no doubt that such damage has caused considerable economic losses. The main objective of this research is to provide new data to develop a robust analytical framework for vulnerability assessment of RC wall buildings and propose new alternatives for damage control by means of seismic protection devices. To reach these objectives, this research is divided in three phases: (i) development of fragility functions for RC wall buildings; (ii) development of vulnerability functions for such buildings by means of estimating economic losses and resilience; and (iii) to control expected damage in RC wall buildings through the incorporation of seismic protection devices. This research will concentrate in RC wall buildings with a “fish-bone” type floor plan configuration, typically used for residential use in Chile and other seismic countries.
