  • Non-Linear Analysis of Side-Plated Reinforced Concrete Beams considering Longitudinal and Transverse Interlayer Slips [Elektronski vir]
    Kolšek Češarek, Jerneja, 1984- ...
    A new mathematical model and its finite element formulation for the non-linearanalysis of mechanical behaviour of a constant cross-section planar beam strengthened with plates bolting or adhesive ... bonding to its sides is presented. The following assumptions are adopted in the model: for each layer (i.e. the beam and the side plates) the geometrically linear and materially non-linear Bernoulli's beam theory is assumed, materials can in general differfrom layer to layer, the debonding phenomena between the side plate and the beam due to, for example, a local buckling of the side plate, is not possible. Regarding the connection of the beam to its side plates at the interface, both the longitudinal as well as the transverse partial interactionbetween layers are considered. The suitability of the theory is validated by the comparison of the numerical solution and experimental results. A good agreement between both results is observed for all load levels. The solution is finally employed in analysis of the effect of two different positions of strengthening plates (i.e. plates to the sides of a beam and tension-face plates) on the performance of a plated beam. The analysis reveals that the side plates, when compared to the alternative tensile-face strengthening plates, can very efficiently enhance the bearing capacity of flexural beams and can in some cases even exhibit a lower rate in loss of ductility of structural response, especially when the interlayer connection is sufficiently stiff.
