The Effect of Strengthening Methods on the Performance of Reinforced Concrete Columns against Vehicle Impact

Columns at the ground floor and parking garages that could be hit by a car pose significant risk to structural stability of building superstructures. Generally, these columns are not built sustain lateral impact force generated car–column collision. In this study, performance axially loaded retrofitted reinforced concrete (RC) against is evaluated using finite element (FE) simulation. The FE model RC column with axial load was validated experimental results. For car-crushing simulations, two SUV models mass about 2250 kg, which had been experimentally validated, were used simulate results analysis revealed once speed exceeds 30 km/h, horizontal has effect on joint foundation. increases linearly as velocity up 20 km/h. When velocities more than in power car-crashing velocity. Both types cars have almost same generation displacement column. It found forces higher recommended design values Eurocode 1. To protect from damage, column-strengthening systems investigated. One form strengthening system involves retrofitting lower half an aramid fiber-reinforced polymer (AFRP) warp, while other putting jacket 1.3 m height Based comparative recommendations suggested accidental damage.
