Rapid Prediction Model for Seismic Damage in Mega Composite Frame Structures Based on IPOA Methods
To rapidly assess the extent of seismic damage in mega composite frame structures
this study introduced a multi-parameter seismic damage prediction method utilizing Improved Pelican Optimization Algorithm (IPOA). Five models with different parameters were developed
and dynamic response data for the structures were obtained through shaking table tests and nonlinear time-history analyses using finite element (FE) software. Structural damage indices were quantified to assess the extent of damage. Additionally
the traditional Pelican Optimization Algorithm (POA) was enhanced by incorporating K-means clustering optimization and inertia weight adaptive optimization strategy. Based on the data from shaking table tests and FE analyses
the accuracy of structural damage predictions using different input parameter combinations was compared. A rapid prediction model using an intelligent algorithm was constructed to reflect the nonlinear relationship between structural parameters and its damage. Finally
the model's predictions were compared and verified against the seismic damage extent from shaking table tests on a 1/15 scale model. The results indicated that: (1) The IPOA model exhibited superior accuracy and generalization capability compared to other algorithm models; (2) The maximum inter-story drift angle showed the highest correlation with structural damage. The introduction of additional input parameters that affected structural damage could enhance the model's prediction accuracy and its generalization capability; (3) The predicted structural damage indices exhibited an error of less than 10% compared to the experimental results
and the predicted levels of structural damage aligned with the experimental results. The proposed rapid prediction model can effectively and accurately predict structural damage indicators.
