• Abstract:

  Most methods for optimizing the position parameters of segmented buckling-resistant support stop plates are based on simplified mechanical models. By combining experimental data and engineering experience, empirical formulas are derived to relate the stop plate position parameters to support performance metrics. However, due to the difficulty in accurately simulating complex mechanical behavior, the quality of parameter optimization is often poor. To address this, a method for optimizing the position parameters of segmented buckling-resistant support stop plates based on Abaqus is proposed.Comprehensively considering factors such as material properties, boundary conditions, and applied loads, this study utilizes Abaqus software to define steel constitutive models, contact properties, constraints, and loading conditions, with the center-to-center spacing of the stop plates and the distance from the end to the end point as the optimization parameters. Through static loading simulations, the equivalent bending stiffness and maximum buckling displacement are calculated to simulate the mechanical response of the support under various operating conditions.Balancing the support’s buckling stability with the requirement for lightweight material usage in the stop plates, and incorporating stiffness constraints defined by engineering design codes, a multi-objective optimization mathematical model for stop plate positioning was established.The Sparrow Search algorithm was employed to map the stop plate position parameters onto a sparrow population position vector. Mechanical responses were obtained through Abaqus simulations, and individual fitness was calculated. The population was updated according to the update rules, ultimately outputting the optimal layout parameters for the stop plates.In the experiment, the proposed method was evaluated for optimization quality. The test comparison results clearly demonstrate that when the proposed method is used to optimize the position parameters of the buckling-resistant support’s stop plates, the maximum lateral buckling displacement is approximately 0.94 mm, indicating a relatively ideal optimization effect.
