Hybrid Steel/NSM/GFRP System Versus GFRP Wrapping for Upgrading RC Wall-like Columns

Polymers, 2023
Reinforced concrete (RC) wall-like columns are commonly employed in structures in Saudi Arabia. These columns are preferred by architects owing to their minimum projection in the usable space. However, they often need strengthening due to several reasons, such as the addition of more stories and increasing the live load as a result of changing the ...

Initial stiffness of integrally-formed GFRP T-joint in GFRP transmission tower

Scientific Reports
It is recognized that the semi-rigidity of the glass fiber reinforced polymer (GFRP) joint should be considered in the structural analysis of GFRP structures, because of the relatively small initial stiffness resulting from the intrinsic property of GFRP material. Regarding the integrally-formed GFRP T-joint in the GFRP transmission tower, the study of

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...
