In this research, the beginning and expansion of the collapse of reinforced concrete buildings were modeled dynamically due to the collision of the vehicle with the ground floor columns. For this purpose, a four-story reinforced concrete structure with a modular framing system was designed using ETABS software under conventional, dead, live and earthquake loading, and then was modeled and loaded in SAP2000 software. By performing nonlinear dynamics analysis of the type of time history, critical forces were determined for failure of the column in the percentages of different live weight participation with correct and error, and then using the physics relations, critical speeds for vehicles with four, eight, and twelve tons Finally, the progressive failure of the building was evaluated by the sudden removal of the column. The results showed that by increasing the percentage of live weight participation, the critical force is reduced, resulting in lower critical speeds for each mass, and the corners of the corners are the most critical column for progressive failure.
