| Abstrait: | The mechanics of masonry structures have been for a long time pushed aside in university teaching during the bachelor degree of architecture in comparison with other fields of knowledge, such as reinforced concrete, steel and wood. An important part of our building heritage is raised using techniques once widely spread but now forgotten in the construction practice as well as in the theoretical university framework, more focused on contemporary and innovative technologies. Developments regarding computational software like FEM macro/micro modelling and discrete element methods allow us nowadays to carry out extremely complex analysis of accomplished masonry structures. Paradoxically, at the same time, this distances itself from the limitations and the way ancients conceived and understood architecture. Master bricklayers and stonemasons were able to build wonderfully without the help of such precise tests on the materials. Therefore, the mind-set when tackling the teaching of masonry structures should be that one where it is forced to the student body to take ownership of the knowledge of the geometry, constructive techniques and processes according to the precise historic period, keeping the tradition alive. The purpose of this work is to present a teaching methodology mainly based on optimization programs for masonry structures. It is illustrated with the analysis of the construction process of the colonnaded portico with double arches of the Great Mosque of Cordoba. The requirement of hypothetical auxiliary resources, such as wood props for the fixation of the capitals and tightening structures will also be considered. This methodology should be understood as a progressive path with a knowledge gradient through a graphical-numerical study that involves the use of four programs: Geogebra, Autocad + Excel, Maple and Sap2000. In this way, the same problem of the thrust line falling within the boundaries of the archery is solved in various ways to understand graphic statics from different perspectives. Moreover, creating a personal optimization model sheet will be taught as a way of accelerating and “systematizing” the calculation. The study will be followed by more complex analysis using symbolic calculation programs. As a result of the learning process described, the limitation and difficulties of each way of approaching the stability problem of the archery will be understood. Not only that, but also students will take advantage of the freedom offered when proceeding to the limit analysis suited to their own interests, always having graphical support. |
