| Sumario: | [EN] The graphical analysis of equilibrium goes back to the beginnings of the theory of arches. In retrospect, it seems obvious, since one only has to use the law of composition of forces, discovered by Stevin at the end of the 17th century. However, it took two and a half centuries before, in the middle of the 19th century, the combination of the line of thrust concept with graphical tools enabled architects and engineers to analyse first arches, then domes, spatial vaults, and complex buildings. These graphical methods were then considered approximate or incorrect because of the concentration on elastic analysis. Professor Heyman demonstrated in the 1960s that the use of equilibrium methods, with a material strength condition (masonry must work in compression), leads to safe solutions. Today, equilibrium analysis is modern and classical elastic theory is old , even if it is formalised with complicated computer programs. The story is interesting in itself, but perhaps it also sheds light on the resistance that exists today against the use of these equilibrium methods. |
