Resumen
[ES]El TFG consiste en el estudio del comportamiento sísmico en obras de patrimonio y su reacondionamiento estructural. Concretamente, se ha analizado la estructura del crucero de la iglesia de Santiago de Lorca (Murcia). Para ello, se ha procedido a realizar un modelo de elementos finitos pudiendo detectar del análisis, los principales problemas cuando se aplica la carga sísmica, tanto del terremoto que indica la norma sismorresistente vigente (NCSE-02) como el que produjo su derrumbe parcial en mayo 2011. Se ha observado el efecto pernicioso de elementos constructivos apeados y la concentración de daño en estructuras sometidas a terremotos de tipo impulsivo de campo cercano. Finalmente, se proponen como medidas de reacondicionamiento estructural para soportar cargas sísmicas refuerzo del arco con chapa metálica, mejora de la unión arco-pilastra con tirantes pretensados anclados, así como refuerzo de las pilastras mediante confinamiento con bandas de fibra de carbono (“Fiber Reinforced Polymer”- FRP).
[EN]This study shows the seismic behavior of cultural heritage buildings and its structural retrofitting. Specifically, we have analyzed the structure of the cruise of the church of Santiago de Lorca (Murcia). For this, a finite element model has been carried out by obtaining the structural problems through the analysis when the seismic load is applied for both, the earthquake puts forward by the current Spanish Seismic Code (NCSE-02) and the another one that led to the collapse of the structure in May 2011. Damage concentration on arches which bear high concentrated load has been observed when the structure is subjected to pulse-like near field earthquakes. Finally, some seismic retroffiting measures are put forward to bear seismic actions such as strengthening of the arches with steel plates, improvement of the arch-column connections with prestressed anchored tie rods, and confinement of piles by means of "Fiber Reinforced Polymer" - FRP).
