In order to respect the more stringent emissions regulations, the weight of the bus must be optimized. The bus structures weight can be lowered by decreasing the thickness of the its components. By doing so, the stiffness of the structure will be affected. A deeper understanding of how different elements influence the stiffness is necessary, for optimizing the bus structure. The aim of this paper is to study the influence of the roof frame on the stiffness of the bus structure. Two cases are studied, one in which the roof frame forms a common body with the side frames, and one in which the roof frame is a standalone component, attached to the side frames via connecting elements and steel plates. The stiffness and the weight of the two bus structures are compared. Using a standalone roof frame gives a better flexibility for optimizing the structure, by choosing a different thickness or material for the frame, increasing the stiffness and reducing the weight.
