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 (T<sub>1</sub>), was used as the first component of the vector and the Maximum Soil Acceleration (AMS), Maximum Soil Velocity (VMS), effective duration (T<sub>D</sub>), seismic potential (I<sub>D</sub>) and the spectral shape parameters R<sub>T1, T2</sub>, Np<sub>Sa</sub>, Np<sub>V</sub>, and Np<sub>Sv</sub>, 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 &lt;Sa (T<sub>1</sub>), Np<sub>Sa</sub>&gt; compared to the other parameters; especially regarding Sa (T<sub>1</sub>) which is widely used in current building codes. Therefore, it is desirable that future building regulations should consider more appropriate seismic intensity measures.</em></p>}, number={2}, journal={Revista de Ciencias Tecnológicas}, author={Zavala Gutiérrez, Noel and Bojórquez Mora, Edén and Barraza Guerrero, Manuel Antonio and Bojórquez Mora, Juan and Villela y Mendoza, Almendra and Torres Peñuelas, José Ignacio and Campos Gaytán, José Rubén and Sánchez Vergara, Ricardo}, year={2022}, month={Apr.}, pages={e220} }
