Análisis por desempeño de pórticos de acero arriostrados excéntricamente tipo Y con diferentes longitudes de vínculos

Orlando Guerrero-Verdugo, Juan Barbecho-Chuisaca

Resumen


La existencia de actividad sísmica debido al movimiento continuo de las placas tectónicas ha conllevado la búsqueda para lograr construcciones que sean capaces de soportar las fuerzas laterales creadas por estos eventos. Existen varios sistemas estructurales capaces de disipar la energía que genera un sismo. Dentro de los cuales se encuentran los pórticos de acero arriostrados excéntricamente (PAE). Diferentes estudios de estos sistemas han demostrado que presentan una mayor rigidez y ductilidad que sistemas convencionales. Estos sistemas concentran el daño en el elemento de unión entre el pórtico y el arriostramiento (vínculo), que puede ubicarse en diferentes configuraciones. Por otro lado, se ha encontrado una diferencia de comportamiento del sistema en función de la longitud del vínculo, clasificándolo en vínculos: cortos, intermedios y largos. En este estudio se realiza la comparación de PAE con los tres tipos de vínculos en configuración tipo Y. Para la evaluación del comportamiento se plantea un análisis estático no lineal (pushover) a través de modelos de elementos finitos elaborados en el software ABAQUS. A partir de lo cual se realiza una comparación de la curva de capacidad y capacidad de rotación del PAE con cada vínculo. Obteniendo como resultado que los vínculos cortos otorgan una mayor rigidez y ductilidad que los vínculos intermedios y largos.
