Some developments in limit analysis of reinforced concrete structures and structural elements

After some recalls of previous contributions to frame and arches analyses, this paper proposes a coupling of Limit Analysis and Framework Modelling in studying R.C. membrane elements. Such a discretization technique, in addition to the determination of the load multiplier and the mechanism of collapse of the structure, allows also to provide useful indications on the position and orientation of the compressed struts and on the distribution of the plasticization in the tensioned elements, with results comparable with those of conventional strut and tie models.
