With the rapid development of China's economy, the design of bridges has also made considerable progress. Starting with the model requirements and competition rules of the comprehensive ability competition of engineering training, this thesis designs an arched truss bridge after comparing the concentrated bridge structures. The bridge has simple structure, clear and concise stress and beautiful appearance, and can give full play to the compression resistance of paper made from bamboo. The finite element analysis software ANSYS is used to analyze and calculate the strength, stiffness and stability of the bridge model. The experimental results prove that the designed bridge can bear the load of 20 kg.
