Bus is one of the top transportation choices in Indonesia, and the amount of the bus keep advancing every year. Despite that, in Indonesia there is one accident in every 321 buses while in America there’s only 1 accident in 1.568 buses. The most fatal crashes among all the crashes type is the rollover type. Bus structure crashworthiness are important in rollover crash because the bus structure receive the biggest impact in rollover crash. One of the indicators of the crashworthiness is the strength of the bus structure. To increase the bus structure strength, reinforcement could be added to the wall-floor connection of a bus structure. This method however needs to be tested to see the effectiveness. There are some options in bus structure strength testing, and one of them is by using numerical simulation. Still, numerical simulation needs to be validated by experimental testing according to the approval method of Crash and Safety Testing Standard for Paratransit Buses (FDOT). Experimental validation is done using the strength test equipment from previous research. The equipment measures the maximum load the structure can withstand along with the angle of the intrusion so the result can be compared with the simulation. On this research, the strength between bus structure without reinforcement and bus structure with reinforcement will be compared to see the best reinforcement for the bus structure. The maximum load and the intrusion angle will be compared with the experimental result as validation.
