Kereta Ringan Hybrid dan Cerdas is one of the modern modes of transportation which designed by carrying out the concept of a hybrid high-speed train. With this capability, the adequate structural strength is needed to accommodate the loads that occur during the operating time of the train. This research analyzes the static and dynamic loading of bogieframe structure which operating at high velocity. Static loading analysis is carried out by implementing exceptional loads which refer to standard to determine the resistance of the bogie frame structure against exceptional conditions. Dynamic loading analysis is intended to obtain stress spectrum for fatigue calculations based on the cumulative damage approach. The stress spectrum is grouped by rainflow counting method. Thus the fatigue life is calculated based on Miner's rule equation. All of Static and dynamic simulations are simulated by using Abaqus software. Fatigue life calculation is approximated by assuming that the train only takes one trip route from Makasar to Parepare which have 140 km length of route. Based on the calculation results, the fatigue life for the bogie frame structure is 10.32 years or equivalent to 3766 trips.
