The shear performances of simply supported (SS) and continuous (CN) reinforced concrete T-beams strengthened with deep embedded (DE) steel or carbon fibre-reinforced polymer bars are compared in this investigation. A nonlinear finite element (NLFE) analysis is performed for this purpose by modelling these beams with the FEM software by validating with the experimental data from the published studies. The experimental and NLFE shear strength values are then compared with those of the available design models to examine the efficacy of these models. Thereafter, the parametric study is conducted to obtain the impact of beam types (SS and CN) on the structural performances. It shows that the DE-strengthened CN beam provides higher shear capacity in comparison to the corresponding SS beam. However, the enhancements of the shear strength of SS beam due to strengthening with DE bars are significantly higher than that of the corresponding CN beam. [ABSTRACT FROM AUTHOR]

This paper reports a detailed numerical investigation on the buckling aspects of laminated composite shell panels of three forms (cylindrical, spherical and hyperbolic paraboloid) with five support conditions exposed to linearly varying in-plane edge load employing eight nodded isoparametric finite element formulation. The impacts of different parameters including ply orientation, load factor, shell forms, aspect ratio, modulus ratio, curvature ratio, width-to-thickness ratio and angle of lamination on the buckling load of shell panels are examined. It is found that the various parameters addressed in this study have a remarkable impact on the buckling phenomena of laminated composite shell panels. Further, a comparison is made showing the effects of five types of compressive edge loads like uniform, triangular, parabolic, partial edge load and point load on the buckling phenomena of laminated shell panels with respect to five support conditions.
