Seismic fragility of a reinforced concrete building using vector-valued seismic intensity measures based on spectral shape

Vector-valued seismic intensity measures have shown to be more efficient compared to traditional intensity measures for predicting the response of structures with non-linear behavior or those dominated by higher modes; however, few studies have demonstrated the capability of these new measures to es...

description	Vector-valued seismic intensity measures have shown to be more efficient compared to traditional intensity measures for predicting the response of structures with non-linear behavior or those dominated by higher modes; however, few studies have demonstrated the capability of these new measures to estimate the seismic fragility of buildings with good accuracy. In the present work, eight vector-valued seismic intensity measures composed of two parameters were analyzed. For all cases, the pseudo-acceleration at the fundamental mode of vibration of the structure, Sa (T1), was used as the first component of the vector and the Maximum Soil Acceleration (AMS), Maximum Soil Velocity (VMS), effective duration (TD), seismic potential (ID) and the spectral shape parameters RT1, T2, NpSa, NpV, and NpSv, as the second component of the vectors. In order to evaluate the efficiency of the selected intensity measures in the seismic fragility analysis, a 10-level reinforced concrete building was subjected to 30 narrow-band seismic records obtained from México City. The results have shown that the vector-valued seismic intensity measures that presents a better relation with the probability of failure is <Sa (T1), NpSa> compared to the other parameters; especially regarding Sa (T1) which is widely used in current building codes. Therefore, it is desirable that future building regulations should consider more appropriate seismic intensity measures.

Las medidas de intensidad sísmica vectorial han demostrado ser más eficientes en comparación con las medidas de intensidad sísmica tradicionales para predecir la respuesta de estructuras con comportamiento no lineal o aquellas dominadas por los modos superiores; sin embargo, pocos estudios han demostrado la habilidad de estas nuevas medidas para una   estimación apropiada de la fragilidad sísmica de edificios. En el presente trabajo se analizaron ocho medidas de intensidad sísmica vectorial compuestas por dos parámetros. Para todos los casos se utilizó la seudoaceleración en el modo fundamental de vibración de la estructura, Sa(T1), como primera componente del vector y la Aceleración Máxima del Suelo (AMS), Velocidad Máxima del Suelo (VMS), duración efectiva (TD), potencial del movimiento sísmico (ID) y los parámetros de forma espectral RT1,T2, NpSa, Npv y NpSv, como segunda componente del vector. Para evaluar la eficiencia de las medidas de intensidad sísmica vectorial en el análisis de fragilidad sísmica, un edificio de concreto reforzado de 10 niveles es sometido a 30 registros sísmicos de banda angosta obtenidos en sueño blando de la Ciudad de México. Los resultados demuestran que la medida de intensidad sísmica vectorial que presenta una mejor relación con la probabilidad de falla es <Sa(T1), NpSa>, en comparación con las otras medidas, especialmente respecto a Sa(T1) que es ampliamente usada en los códigos de construcción vigentes. Por lo tanto, es deseable que en los futuros reglamentos de construcción se consideren medidas de intensidad sísmica más apropiadas.
