The method is based on energy balance principles and a predefined target drift. However, its reliance on lateral load calculations often results in reduced strength of structural members, particularly in low- to medium-rise buildings where beam sections frequently fail to meet safe design requirements. This limitation raises concerns about the safety and reliability of PBPD-designed structures. To address this issue, an improved PBPD method is proposed by incorporating the minimum reinforcement criteria for beams as specified in the Indian design code. A 10-story reinforced concrete special moment-resisting frame was designed using the improved PBPD method and compared with a frame designed using the conventional force-based design approach. Nonlinear Pushover Analysis and Nonlinear Time History Analysis under strong Turkish ground motions were performed to evaluate the seismic performance of both designs. The results indicate that the improved PBPD method significantly enhances the seismic performance of the structure. The maximum considered earthquake level performance point of the PBPD frame lies within the Collapse Prevention range, while its overall drift ratio is 19.82% lower than that of the Force Based Design (FBD) frame. Incremental Dynamic Analysis further shows that only one ground motion exceeded the target drift of 0.02 for the improved PBPD frame. Additionally, fragility analysis demonstrates that the probability of complete failure is reduced to 17.2% for the PBPD frame, indicating superior robustness and reliability compared to the FBD frame.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"26 3","pages":"1355 - 1371"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional methods often rely on manual testing and empirical formulae, which can be time-consuming and error-prone, respectively. In this study, the advanced machine learning techniques are employed to predict the strength. The paper explores multiple base models, such as linear regression (including polynomial features up to degree 3), decision trees, support vector machines, and k-nearest neighbors. Hyperparameter tuning is utilized to improve the models and cross-validation is carried out to check any overfitting issues. In addition, artificial neural networks and ensemble learning methods such as voting, stacking, random forest, gradient boosting, and XGBoost are implemented. Two datasets from different sources are utilized in this study. Results indicate that models trained on one dataset do not perform satisfactorily on second dataset and vice-versa, due to covariant shift in the datasets. In fact, this approach implied that rather than relying on advanced machine learning models, linear regression gave approximate results. After combining these datasets, the models were successful in generalizing over wider range of features. The results show that gradient boosting achieved the highest accuracy with an R<sup>2</sup> score of 0.93 and an RMSE of 3.54 for the training data of combined datasets. The paper further delves into finding the lower and upper bound of the predictions with 95% confidence interval using bootstrapping technique. The author recognizes the necessity of diverse datasets to improve model generalization. However, if the models are trained on limited datasets, and inference is to be made on those with different distributions of features than training data, then the prediction interval can be the indication of the confidence of the models. Further for inference on new unseen data, Mahalanobis distance is measured to indicate whether the data is outlier, thus improving the reliability.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"26 3","pages":"1225 - 1241"},"PeriodicalIF":0.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonlinear dynamic and pushover analyses assessed parameters such as story drift, roof displacement, and strain responses. Steel bracing configurations (center core, exterior corner, and exterior side) significantly improved seismic resilience by enhancing lateral stiffness, reducing displacement, and controlling drift. Results showed center-core bracing as the most effective configuration, achieving displacement reductions up to 52.32% and drift reductions up to 59.98%. Bracing also minimized the formation of plastic hinges, enhancing energy dissipation and structural integrity. The study highlights the impact of brace placement, building height, and earthquake intensity on seismic performance. At the same time, shorter buildings exhibited more pronounced benefits and taller structures required optimized bracing strategies to increase flexibility and lateral force demands. These findings emphasize the necessity of steel bracing for improving seismic safety and resilience in reinforced concrete buildings, particularly in earthquake-prone regions, and provide insights for future seismic design and retrofitting practices.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"26 3","pages":"1321 - 1338"},"PeriodicalIF":0.0,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
