This paper deals with structural analysis of bus superstructure undergoes rollover event. Bus superstructure with varying beam profile size will undergo rollover simulations analysis. The purpose of this work is to analyze structural response of bus superstructure in terms of deformation, stress and strain under several loadings and constraining conditions. These rollover simulations were run according to United Nation Economic Commission of Europe Regulation 66 (UNECE R66). Validation procedure using simple box modeled undergoes rollover have been done to ensure the results are synchronized with real problem. An interaction with bus coach builder allows author acquired accurate bus superstructure dimensions before designing the mathematical model in finite element analysis software. Three full-scale bus superstructures mathematical model with difference cant-rail horizontal roof beam profile size was developed and the deformation of superstructure during and after rollover testing had been study. Analyses suggested that one of the contributing factors that lead to the failure of bus having rollover accident is cant-rail and roof structure profile size. © (2013) Trans Tech Publications, Switzerland.
