Abstract |
Box-type structures have been widely employed in civil engineering from ancient times to the present, serving essential roles in the construction of various infrastructure systems such as water supply and drainage, urban gas lines, electricity and telecommunications, highways, and railways. Their usage is expected to increase further in both frequency and scale. Currently, the FEM is the predominant analytical technique used to evaluate the safety of these structures. While FEM offers precise and reliable results, it often demands considerable time and effort due to the complexity of modeling and simulation, particularly when applied to large-scale structures. This can lead to inefficiencies in the design and review process. To address these limitations, this study performed both static and seismic analyses of box structures using FEM, and subsequently utilized the resulting data to train a deep learning model aimed at predicting structural member forces. A total of 600 numerical models were developed using MIDAS software. The predictive performance of the deep learning model was assessed using metrics such as Mean Squared Error (MSE), Mean Absolute Error (MAE), and the coefficient of determination (R2). The results indicated that the model's performance under static loading conditions was superior to that under seismic conditions, which may be attributed to the complexity introduced by dynamic responses. This study highlights the potential of deep learning as a complementary approach to traditional FEM-based structural analysis. The proposed methodology offers a promising avenue for enhancing the efficiency of structural safety assessments and design processes in future engineering applications |
