RC two-way slabs strengthened with CFRP strips: experimental study and a limit analysis approach

Strengthening of steel-reinforced concrete structural elements by externally bonded FRP sheets and evaluation of their load carrying capacity

“…Limit analysis approaches can be really useful from an engineering point of view because allow the direct evaluation of the load bearing capacity of a structure [12,13,20]. In its classical formulation the theory of limit analysis refers to perfectly plastic structures, made of standard materials, and is based on two fundamental theorems, namely: the upper and the lower bound theorem [14,27].…”

Enhanced layerwise model for laminates with imperfect interfaces – Part 2: Experimental validation and failure prediction

“…In [24], Diaz and Caron predicted accurately thickness and ply angle effects on delamination onset in cross-ply carbonepoxy laminates by making use of the M4-5N layerwise model and a criterion involving the interfacial stresses. Dallot and Sab [25] and Limam et al [26] have also proved the potential of layerwise methods in predicting failure with a limit analysis approach.…”

Investigation on Strengthening Approaches Adopted for Poorly Detailed RC Corbels

“…FRP application has been experimentally verified to be effective in improving the shear and flexural capacity in a beam and a slab [4] and ductility in a column due to the confinement offered by FRP wrap [5]. In addition, the application of horizontal CFRP laminates has been proved to be effective in shear strengthening of deep beams with lower shear span to depth ratio, which are designed on similar principle as corbels though CFRP effectiveness will greatly vary depending upon shear span to depth ratio and fiber orientation [6].…”
