Adopting the displacement-based probabilistic seismic vulnerability assessment methodology, the sensitivities of the parameters of the beam-sway RC frames are studied. These parameters include the peak ground acceleration, the structural beam geometric parameters and the material parameters. The analyses show that the vulnerability assessment results will change obviously when the mean values of peak ground acceleration, the beam geometric parameter and the limit state strain of reinforcement bar are changed. The coefficients of variability of the above parameters also affect the vulnerability assessment results while not so obvious compared with their mean values. The limit state strain value of concrete will affect little on the vulnerability assessment results.
