Abstract Scope |
Glass fibre-reinforced polymer (GFRP) composites have become increasingly popular as alternative materials for building applications. One prevalent loading scenario for GFRP members in building structures involves eccentric compression. In such cases, the shear stresses induced by second-order effects may precipitate shear and delamination failure before experiencing compressive or tensile failure, owing to the relatively low shear strength of GFRP composites compared to their compressive and tensile strength. This study presents an investigation into pultruded GFRP laminated plates subjected to eccentric compression loading through a series of experimental tests and numerical finite element modes.
Two types of failure modes were observed in the experiments: compressive/tensile failure mode and shear and delamination failure mode. By establishing a coordinate system with slenderness as the horizontal axis and eccentricity ratio as the vertical axis, zones for shear failure and compressive/tensile failure were identified. Additionally, a curve delineating the two zones was developed. The results obtained from this study offer valuable insights for engineering designers. |
