DESCRIPTION:In this talk we discuss the findings of a recent study on rein
 forced concrete elements subjected to shear. Starting from a prismatic ref
 erence geometry\, a preferential internal load-path was progressively isol
 ated. Volumes of concrete that were not part of this resisting mechanism w
 ere replaced with a low-strength concrete\, or left unfilled. This led to 
 a net increase in overall resistance and ductility of the specimens. The r
 emoval of material from the structure\, and the decrease in material stren
 gth in some regions of the structure\, strengthened it. This paradox and t
 he counter-intuitive results of the study are explained with new concepts 
 such as ‘shear compliance’ and ‘engineered crack propagation’\, bu
 t also through the analysis of historical structures.  \n\n\n\nJoin Zoom M
