Therefore, in this study, the reliability analysis of steel moment-resisting frame structure with 2-story has been conducted under the impact of light vehicle collision considering uncertainty in material and applied loads using simulation-­based methods. The mentioned structure is modeled in OpenSees software two-dimensionally and the sensitivity analysis of the studied random variables is performed using Monte Carlo simulation-based method in Matlab software. Then, the limit state functions are proposed based on the maximum permitted beam rotation of the damaged bay. Finally, the failure probability and reliability index of the mentioned frame is investigated and compared according to performance levels under the impact of a light vehicle collision with speeds 20, 40, 60, and 80 Km­/­h. The results showed that the random variables such as mass and velocity of vehicle and yield strength of material were the most influential in the failure probability and the control variates-based subset simulation method compared to Monte Carlo method estimated the failure probability with a permissible error rate, less sample number, and short running duration.
