| Abstract | ||
| The structural performance of concrete skew panels is a vital parameter in civil engineering, especially in complex loading conditions. In this paper, a new approach is presented to improve the performance of skew cylindrical concrete panels by the use of nanocomposite reinforcement. In particular, the study evaluates functionally graded graphene oxide reinforced concrete (FG-GOPRC) as the reinforcement option of skew panels, utilizing this nanocomposite's mechanical properties under a variety of loading cases. The reinforcement will take on the Halpin-Tsai homogenization method of modelling to provide an accurate prediction of effective properties of the composite based on volume fraction and geometrical configuration of the nanomaterial in the concrete matrix. In order to derive the governing equations for both the bending and vibration analysis of the skew panels, a variational version of Hamilton's principle alongside the first order shear deformation theory (FSDT) is utilized. The Chebyshev-type Ritz technique is then employed to simply, yet accurately solve the governing equations. This allows for a comprehensive investigation on the influences of nanocomposite reinforcement on the concrete skew panels vibration characteristics. The results indicate that the FG-GOPRC nanocomposites produce a substantial increase in load capacity and durability when compared to conventional reinforcement types. These results have implications in the design and optimization of concrete panels for engineering purposes, especially when dealing with critical infrastructure under dynamic and static loading conditions. This study advances the field of nanoresearch in structural engineering, and suggests an effective and efficient method for concrete skew panels. | ||
