    Las catedrales de Santiago y La Paz: alcances históricos, arquitectónicos y patrimoniales
    (2021) Barrientos, Marco; Pérez V., Blanca Elvira; Mariaca, Cristian
    El trabajo examina las catedrales de Santiago, Chile y La Paz, Bolivia desde una mirada histórico-arquitectónica, para comprender sus alcances en el campo del patrimonio religioso durante el periodo de transformaciones más importantes en cada caso (1835-1932). Se propone un análisis comparado para identificar similitudes y diferencias en los factores que explican los procesos de construcción de cada caso, con énfasis en las intervenciones de que fueron objeto, enmarcadas dentro de un contexto cruzado por las celebraciones del centenario de las nacientes repúblicas, y su impacto en la imagen urbana de ciudades como Santiago y La Paz.

    Seismic Vulnerability Assessment of the Yungay's Historic Urban Center in Santiago, Chile
    (2022) Chiara Palazzia, Nuria; Barrientos, Marco; Sandoval, Cristián; Llera Martín, Juan Carlos de la
    In this paper, a modified empirical large-territorial-scale procedure to assess the seismic vulnerability of aggregate buildings in urban areas located within a highly seismic context is proposed. The methodology is applied to a group of unreinforced masonry (URM) aggregates located in the Yungay's historic center in downtown Santiago, Chile. This assessment was carried out by modifying and integrating a vulnerability-index-based procedure, a specific existing approach called first level macro-seismic method used to predict seismic damage and loss scenarios through fragility curves of structural components. The procedure was calibrated using the observed damage after the 2010 Chile earthquake in 292 URM structural units. The results of this new damage index for URM aggregate buildings are used to derive Probability Mass Functions (PMFs) of the different damage states and preliminary Empirical Fragility Functions (EFFs). To the best of the authors' knowledge, these EFFs are the first publicly available for aggregate Chilean URM buildings. This research and its results are the starting point for a more comprehensive study for assessing damage sce-narios and vulnerabilities of aggregate URM buildings in historic centers of older Chilean cities. These functions may be used in risk assessment, and are useful to prioritize possible future damage mitigation strategies and other processes involving this historical heritage. We foresee that these results could be at least partially applied to other historical urban areas in Chile, and perhaps other old Latin American cities located along the sub-duction convergence region between the Pacific and Continental plates, which were founded similarly.
