| contents | Performance Analysis of Self‐Resetting Pier–Beam Node of Sheet–Pile Bridge Based on Vehicle–Bridge Coupling Vibration Xu Shizhan Wang Gang Tang Jiangping Lu Yinfeng Li Chengyu Advances in Civil Engineering To address the issue of excessive stress at the secondary pier–beam joints of multispan continuous sheet–pile bridges caused by large longitudinal displacements, this study proposes a novel structural configuration incorporating prestressed self‐resetting reinforcement at the pier–beam connection. Using an engineering case as a reference, a three‐dimensional girder–grid model of the sheet–pile bridge was established to investigate its global static response. A vehicle–bridge coupled vibration model of the bridge was then developed in ANSYS using the transient dynamic analysis module and the contact‐constraint approach. The dynamic behavior of the self‐resetting pier–beam joint was analyzed under the combined effects of extreme temperature differentials and heavy vehicle loads. Additionally, the influence of varying vehicular impact loads on the dynamic behavior of the self‐resetting joint was examined while keeping other parameters constant. Results indicate that the maximum longitudinal pile displacement and the peak deck shear force occur at the secondary pier support, where ~69% of the longitudinal displacement is attributed to uniform temperature effects and 72% of the deck shear force results from vehicular impact loading. When subjected to both the maximum temperature gradient and heavy vehicle loading, the peak vertical tensile stress at the self‐resetting joint decreases by 24.23% compared with the conventional pier–beam connection, resulting in substantially less damage. Under isolated vehicle‐loading conditions, the self‐resetting joint exhibits enhanced crack resistance under small impact loads and effectively mitigates stress amplitude and structural damage under larger impacts. Upon unloading, only minor damage occurs, and the structure rapidly recovers its original configuration. Incorporating prestressed self‐resetting nodes into prefabricated sheet–pile bridges substantially improves their stress performance and overall safety, offering valuable insights for enhancing their dynamic performance and resilience. 10.1155/adce/8131663 http://creativecommons.org/licenses/by/4.0/ |
