The study analyzed the Haierwa reinforced concrete arch bridge using computer simulations. The researchers found that the bridge's natural frequency follows a common rule, with lower frequencies closer together. The maximum displacement occurs in the middle of the bridge and decreases towards the sides. The stiffness and strength of the arch meet requirements, making it the main load-bearing part of the bridge. The stress distribution is uniform, benefiting the entire structure. Overall, the design of the arch bridge is deemed reasonable and beneficial for future bridge designs.
