Abstract
The presence of openings in reinforced concrete (RC) walls leads to a marked reduction in both axial load capacity and overall stiffness, thereby compromising structural performance. To mitigate these adverse effects and maintain safety, various strengthening methods have demonstrated effectiveness in restoring and enhancing the structural capacity of RC walls containing openings. In the present study, a finite element modeling strategy is proposed and verified against two experimental investigations available in the literature. The comparison reveals strong correlation between the numerical simulations and the experimental findings, confirming the reliability of the modeling approach. Building on this validation, an extensive parametric analysis is performed. The outcomes of this study are then employed to formulate an empirical design expression that incorporates the primary governing parameters for predicting the axial load capacity of one-way RC walls with a single rectangular or square opening retrofitted using externally bonded (EB) CFRP sheets.
Masonry infill walls, although commonly treated as non-structural elements in reinforced concrete (RC) buildings, have a significant influence on the lateral response of RC frames. This study investigates the effects of masonry infills, opening configurations, and wall-post systems on the nonlinear lateral behavior of...

This study investigates the blast response of reinforced concrete (RC) walls with varying boundary element (BE) configurations using a validated macro-model implemented in OpenSees. The model, based on embedded layered-shell elements, was verified against independent experimental and numerical benchmarks, demonstrating...

Perforated and castellated steel beams are widely used due to their high structural efficiency; however, the presence of web openings introduces complex failure modes, such as Vierendeel bending and web-post buckling, which are not observed in solid-web sections. In this study, the influence of geometric parameters on...
