          Abstract

          En el presente artículo se describe el proceso de análisis al que fue sometido un puente histórico de arco de ladrillo construido en Colombia durante el siglo XVIII con el fin de predecir su comportamiento ante cargas producidas por sismos y determinar su vulnerabilidad. Dos estudios previos al análisis sísmico fueron realizados para obtener así información básica acerca del comportamiento global de la estructura: un análisis estático lineal y un análisis modal, ambos a partir de un modelo tridimensional que se elaboró haciendo uso del método de elementos finitos. Se simuló la excitación sísmica bajo las condiciones propuestas en la norma sismorresistente del año 1998 (NSR-98). Los resultados obtenidos fueron coherentes con la historia del puente y sus respuestas frente a terremotos; la comparación entre las cargas sísmicas y la capacidad resistente de los materiales que constituyen la estructura confirma la vulnerabilidad de este tipo de edificios frente a daños localizados y posibilidades de colapso. Finalmente, los resultados sugieren la aplicabilidad del procedimiento desarrollado a otras estructuras históricas en Colombia.

          This article describes the analysis of a historic brick arch bridge constructed in Colombia during the 18th century for predicting its behavior in response to loads produced by seismic activity and determining its vulnerability. Two studies were carried out prior to the seismic analysis to obtain basic information regarding the structure's overall behavior (modal analysis and linear static analysis), both stemming from a threedimensional model constructed by the finite elements method. Seismic excitation was simulated in the conditions proposed by 1998 Colombian seismic-resistant norms (NSR-98). The results obtained agreed with the bridge's history and with its response to earthquakes; the comparison between seismic loads and the resistance capacity of the materials constituting the structure confirms the vulnerability of these types of constructions regarding localised damage and the possibility of collapse. The results suggest that this procedure can be applied to other historic structures in Colombia.
