Amplitud de aceleración del componente vertical de los sismos colombianos

Palabras clave: componente vertical sísmica, relación V/H, relación V/H espectra, aceleración máxima del terreno, distancia hipocentral

Resumen

Estudios anteriores han demostrado que el componente vertical del terremoto puede afectar sustancialmente el desempeño sísmico de puentes y edificios. Este componente generalmente se ignora o, cuando se incluye en el diseño, se estima como dos tercios del terremoto de diseño sísmico horizontal. Este trabajo presenta la caracterización de la amplitud de aceleración del componente vertical de sismos moderados y fuertes en Colombia (Magnitud de momento Mw > 4) ocurridos entre junio de 1993 y abril de 2020. Se registraron un total de 42 registros sísmicos a menos de 50 km del Se seleccionaron planos de ruptura y con picos de aceleración horizontal mayores a 0.05g. Se calcularon la aceleración máxima del suelo (PGA) de los tres componentes y la relación entre esos PGA. Adicionalmente, se determinó la relación entre dichos parámetros y la magnitud y las distancias epicentral e hipo central. Los resultados mostraron que la relación V/H igual a 2/3 no siempre es válida para representar los efectos del componente vertical en estructuras sometidas a movimientos de suelo moderados y fuertes en Colombia.
