When situated near sea, seismic performance of these buildings reduces with time as they are commonly subjected to deterioration due to chloride ion ingress with subsequent rebar corrosion. In this study, the deteriorating effect of rebar corrosion on structural performance of a six-story RC shear wall-frame structure was studied taking into account the reduced bond strength, decreased reinforcement bar diameter, deterioration of steel’s mechanical properties, deterioration in the structural integrity of the concrete cover and a corresponding reduction in the confinement capacity of columns. Initially, the shear walls were independently analysed by modelling them using plane stress element micro-models. The capacity curves of the walls were then evaluated when subjected to 5 and 10% rebar corrosion implementing all the mentioned degradation factors due to corrosion. The six-story RC shear wall-frame structure was then modelled using a macro-model with shear walls modelled as a multi-linear nonlinear link element connected rigidly in the frames and beams along with columns as nonlinear moment hinges. The RC bare frame structure was also similarly modelled. Nonlinear pushover analysis of both the shear wall-frame and bare frame structure was then carried out without and with the effect of corrosion (5 and 10%). Results indicated that ultimate load capacity and ductility of both shear wall-frame building and bare frame building decreases with the increase in level of corrosion with more pronounced effect of corrosion on ultimate capacity of shear wall-frame building.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"27 9","pages":"4647 - 4667"},"PeriodicalIF":0.0,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148807281","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}

In addition to plain GFRP panels, the influence of polymer concrete overlays acting compositely with the GFRP section is also explored. As comparatively thin-walled elements, GFRP components can be vulnerable to localised failures that may arise from concentrated loads. The strategic use of concrete toppings, acting compositely with the GFRP component, can enhance the section’s resistance to such local failures as well as enhancing the overall flexural capacity and stiffness. Currently, no punching shear data on closed form pultruded composite GFRP-concrete deck components are readily available in the existing literature. To address this, six pultruded GFRP deck components (338 mm x 600 mm x 80 mm) were investigated experimentally under concentrated, monotonic load, including two plain panels, two with a 15 mm polymer concrete topping and two with a 30 mm topping. In comparison to the plain GFRP panel, a 67% and 280% increase in ultimate load capacity was observed with addition of the 15 mm and 30 mm polymer concrete topping respectively. In parallel, corresponding increases in initial stiffness of 60% and 199% up to the peak load were observed, demonstrating a good degree of composite action. In the case of the panels with toppings, the onset of punching shear was delayed in comparison to plain panels. For all the cases examined with toppings, no significant de-bonding of the polymer concrete from the GFRP substrate was observed, indicating the suitability of directly bonded toppings in this scenario.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"27 9","pages":"4599 - 4614"},"PeriodicalIF":0.0,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42107-026-01736-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148807282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work establishes a hybrid machine-learning framework that integrates optimized base learners through blending for base shear and stacking for interstory drift ratio to deliver high-resolution, physically coherent response predictions. The model was trained on 500 elastic time-history analyses generated by applying 20 recorded earthquakes to 25 reinforced-concrete frames and evaluated across three excitation contexts: a general dataset, near–far fault classifications, and low–high spectral acceleration partitions. The framework achieved strong predictive performance (R² up to 0.98 for base shear and 0.97 for drift). At the same time, interpretability analyses identified consistent governing predictors, including first-mode period, spectral acceleration, and strong-motion intensity measures. They revealed apparent shifts in the influence of predictors as shaking intensity increased. Uncertainty quantification showed that bootstrap intervals had empirical coverage exceeding 90%, whereas parametric intervals did not adequately cover high-intensity and near-fault motions. This indicates that the error structure is asymmetric and heteroscedastic. Taken together, these findings establish a fast, interpretable, and physically grounded surrogate for dynamic analysis, enabling intensity-sensitive seismic-demand estimation, regional scenario evaluation, and accelerated post-earthquake decision support within performance-based engineering.</p></div>","PeriodicalId":8513,"journal":{"name":"Asian Journal of Civil Engineering","volume":"27 10","pages":"4807 - 4832"},"PeriodicalIF":0.0,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148962264","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}

Eleven simply supported RC beams with dimensions of 250× 300 × 1850 mm and a concrete grade of 35 MPa were cast and tested under two-point loading. The experimental program included one monolithic reference beam and ten jointed beams cast in two stages with a 24-hour interval. The investigated joint configurations were a 45° inclined joint, a 90° vertical joint, a horizontal joint, and a key joint located in the flexural zone, in addition to a 90° vertical joint located in the shear zone. For each joint configuration, one specimen was left untreated, while the corresponding specimen was treated with Old-New epoxy before the second concrete pour. The beams were evaluated in terms of ultimate load, first visible cracking load, load–deflection response, stiffness, ductility, toughness, strain behavior, and crack pattern. The results showed that construction joints reduced the ultimate load compared with the monolithic reference beam, with untreated specimens showing reductions between 8.3% and 13.1%. The epoxy treatment improved the ultimate load of most flexural-zone joints, especially the 90° vertical flexural joint, which achieved a 7.16% increase compared with its untreated counterpart, although it remained 4.5% below the reference beam. The treatment also enhanced cracking resistance, increasing the first visible cracking load by 68.1% for the 90° flexural joint and 88.4% for the 90° shear-zone joint. However, the shear-zone joint showed a 7.01% reduction in ultimate load after treatment, indicating that epoxy alone was less effective under shear-dominated interface conditions.

Despite their cost-effective performance, linear TMDs come with limitations such as reduced effectiveness in case of excitations with broad frequency bandwidth, and the large mass and stroke requirements. Nonlinear stiffness TMDs, on the other hand, have gained considerable attention as they potentially suffer less from the limitations imposed on linear dampers. In this study, a bi-directional magnetic damper, considered as a nonlinear TMD, is numerically compared to a typical linear TMD at different mass ratios. A three degrees of freedom structure equipped with both dampers is subjected to various types of dynamic excitations. The dampers are optimized using a numerical search that minimizes the Root Mean Square (RMS) value of the structure’s displacement response. Results reveal that the proposed damping device outperforms the linear TMD in all loading scenarios, with its superiority being more pronounced under excitations with broad frequency content.
