Since the calculated spring coefficient involves coupling, general finite element analysis software like SAP90 and ALGOR91 do not offer a direct method to handle coupled springs. Therefore, mechanical analysis is required to adapt these programs for solving problems involving coupled springs in structures. The approach involves defining the original structure's spring constraints: D11 represents the compliance of the translational spring at the base, D22 corresponds to the rotational spring's compliance, and D12 is the coupling coefficient between translation and rotation. This paper proposes converting the original coupled spring system into an equivalent non-coupled system. The equivalent system consists of a rigid rod of length L connected to two translational springs with compliance coefficients Da and Db. This configuration can be easily modeled using standard finite element software such as SAP90 or ALGOR91. To establish the relationship between the flexibility coefficients of the original and equivalent systems, a unit force F=1 is applied at one end of the rigid rod, leading to Da = D11 and L = D11/D12. Similarly, applying a unit moment M=1 at the same end results in H = D22, D1a = Da/L, and D1b = Db/L. By substituting these values, we derive Db = (L²D22) - Da, which simplifies to Db = (D11²D22)/D12² - D11. Finally, the stiffness of the equivalent springs are given by Ka = 1/Da and Kb = 1/Db, with L = D11/D12. With this setup, the equivalent spring system can now be analyzed using general-purpose finite element software. A comparison of the results from a cable-stayed bridge model demonstrates the effectiveness of the proposed method. A self-developed finite element program was used to calculate the vibration characteristics of the structure, taking into account the effects of the coupled springs. Additionally, the coupled spring system was converted into an equivalent non-coupled system using the method described in this paper, and the same analysis was performed using SAP90 and ALGOR91. All three programs were used to calculate the first 30 natural vibration periods of the bridge model. The results showed a high degree of consistency, confirming the feasibility of the method. Dynamic response analysis was also conducted on the cable-stayed bridge model using the self-developed program that accounts for the coupled spring effects. The same model was then converted into an equivalent non-coupled system and analyzed using SAP90. Through the example of the Wuhu Cable-Stayed Bridge, the vibration characteristics and dynamic responses of critical structural components were evaluated. The comparison of results from different programs confirms that the method presented in this paper is both simple and effective for handling coupled spring problems, significantly expanding the applicability of general finite element software in engineering practice.
