A kinematic approach for peak load evaluation of concrete elements

Limit analysis on FRP-strengthened RC members

“…Both have been rephrased and widely employed by the authors [14], [15]. Their use to bracket the real peak load value of a structure made of a nonstandard material has been also experienced with success [11]- [13]. All the analytical details of LMM and ECM are in the above quoted papers and are here omitted for brevity.…”

“…The numerical methodology here referred, already used by the authors to predict the limit-state solution of RC elements (see e.g. [11,12]) and of pinned-joint orthotropic composite laminates (see e.g. [14,15]), is quite versatile and is based on iterative linear FE analyses carried out on the structure endowed with spatially varying moduli and, if necessary, given initial stresses.…”

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

“…The two methods are known in the relevant literature as Linear Matching Method (LMM) and Elastic Compensation Method (ECM), respectively. They were conceived in [6,25,15] with reference to von Mises materials and then it has been proved that their applicability is also effective with reference to a more general class of materials [20][21][22][23][24]26] the only requisite being the strict convexity of the involved yield criterion. Both methods make use of linear elastic analyses to mimic the behavior of the structure at collapse and are performed iteratively.…”

Limit State Evaluation of Steel-Reinforced Concrete Elements by Von Mises and Menétrey–willam-Type Yield Criteria

“…and that can be faced by coupling plasticity with fracture or damage mechanical theories within step-by-step analyses (see e.g., Lubliner et al [1989], Lee and Fenves [1998] and Zhang et al [2010]); however, they can give information on the behavior at limit (collapse) states of structures, which are very useful for design purposes. In this context, with an approach not based on an optimization algorithm but grounding on sequences of FE elastic analyses, it has to be inserted to the present study.The promoted approach belongs to a wider research program started by the authors in the context of laminates of fibres reinforced polymers [Pisano and Fuschi, 2007;Pisano et al, 2012Pisano et al, , 2013bDe Domenico et al, 2014] and then extended in the context of RC structures with reference to a Menétrey-Willam (M-W)-type yield criterion with cap in compression [Pisano et al, 2013a[Pisano et al, , 2013cDe Domenico et al, 2014]. In both the latter quoted studies, two limit analysis methods, namely the linear matching method (LMM), and the elastic compensation method (ECM), have been applied under the simplified hypothesis where reinforcements behave as indefinitely elastic.…”
