Over the last few years, the number of motor vehicles in Indonesia continues to increase. Along with the increasing number of vehicles, the number of accidents on motor vehicles has increased. In 2017 the number of motor vehicle accidents reached 103228 cases. One type of motor vehicle that has a large number of accidents is bus. In 2017 the number of accidents reached 2500 units. There are several types of accident cases on buses, such as side-impact and rollover accident. In this study, analysis and design of bus structure reinforcement were carried out which could reduce the risk of passenger injury in the case of side-impact and rollover accidents. The process of design and analysis of bus superstructure and chassis is carried out by referring to American regulations, namely FMVSS 214 for side-impact cases and FMVSS 216 for rollover accident cases. In this study, the analysis of the superstructure strength of the bus against side impact and rollover was carried out using non linier finite element method. After simulating the bus structure using this method, the structure is reinforced by varying the thickness or by adding frames to the place that are not strong at receiving impact loads. In the case of a side-impact, a design that meets FMVSS 214 regulations can be obtained. In this design, reinforcement is carried out by adding thickness at the horizontal side frame to 4 mm. In addition, a number of crash boxes were added to absorb side impact energy on the bus floor structure. In the case of a rollover accident, a design that meets FMVSS 216 regulations can be obtained. The design reinforcement is carried out by increasing the thickness at the roof structure from 2 mm to 4 mm. In addition, a gusset frame was added to the pillar to roof joint structure.
