Resumen

Se ha comprobado que, en caso de terremoto fuerte, y debido a una distancia insuficiente entre dos estructuras adyacentes, el movimiento lateral en la parte superior de las estructuras puede provocar colisiones entre ellas. Este fenómeno, comúnmente conocido como colisión sísmica, puede generar fuerzas de impacto que no se tuvieron en cuenta durante el diseño inicial de la estructura. A su vez, pueden causar daños estructurales significativos o provocar el colapso completo de la estructura. El objetivo principal de este trabajo es estudiar los efectos acoplados de la flexibilidad del suelo y el impacto entre edificios adyacentes sometidos a excitación sísmica. Para capturar las fuerzas de impacto entre las estructuras durante la colisión, se ha utilizado eficazmente un modelo visco elástico lineal modificado. Se ha prestado especial atención al estudio de los efectos de la velocidad de la onda cortante, primero en la interacción suelo-estructura y después en la respuesta de colisión de las estructuras adyacentes. Se analizaron tres configuraciones de estructuras adyacentes: estructuras ligeras-ligeras, ligeras-pesadas y pesadas-pesadas. Los resultados obtenidos mediante este análisis mostraron que la respuesta dinámica y la fuerza de impacto de las estructuras dependen esencialmente de la interacción entre la estructura, la cimentación y el suelo.
