    Development of a fragility model for the residential building stock in South America
    (EARTHQUAKE ENGINEERING RESEARCH INST, 2017-05-01) Villar-Vega, Mabe; Silva, Vitor; Crowley, Helen; Yepes, Catalina; Tarque, Nicola; Acevedo, Ana Beatriz; Hube, Matias A.; Gustavo, Coronel D.; Maria, Hernan Santa; Mecánica Aplicada
    South America-in particular, the Andean countries-are exposed to high levels of seismic hazard, which, when combined with the elevated concentration of population and properties, has led to an alarming potential for human and economic losses. Although several fragility models have been developed in recent decades for South America, and occasionally used in probabilistic risk analysis, these models have been developed using distinct methodologies and assumptions, which renders any direct comparison of the results across countries questionable, and thus application at a regional level unreliable. This publication aims at obtaining a uniform fragility model for the most representative building classes in the Andean region, for large-scale risk analysis. To this end, sets of single-degree-of-freedom oscillators were created and subjected to a series of ground motion records using nonlinear time history analyses, and the resulting damage distributions were used to derive sets of fragility functions. © 2017, Earthquake Engineering Research Institute.

    Función de fragilidad para pórticos de concreto reforzado de baja altura con mampostería integrada en Colombia
    (Universidad EAFIT, 2023) Jaramillo Rivera, Andrea Milena; Jaramillo Fernández, Juan Diego; Lafontaine Roth, Mario Andres
    In addressing uncertainty within seismic risk evaluation in Colombia, this research unveils a fragility curve derived from the nonlinear static analysis of a structure representing the prevalent low-rise residential buildings with concrete frames in the country. The exposure database from an insurance company with a substantial presence nationwide allows it to determine the structural system, the range of floors, and construction periods of interest for assessment. This database facilitated the identification of the type of buildings concentrated in highly populated cities, Bogotá, Cali, and Medellín. The study incorporated acceleration records from seismic threat assessments conducted in relevant investigations. Key characteristics were identified through interviews with various engineering firms in Colombia to select and model the typical building.
