A platform for research: civil engineering, architecture and urbanism
Statics of masonry vaults is the subject of this chapter, divided into four sections. The construction of these vaults has a long history because they were the first curved structures built to cover an underlying space. Masonry vaults have signed the history of architecture since the origins up to the nineteenth century. Many of them have been destroyed during time but many survived and frequently represent outstanding examples of our historic heritage. The study of their statics is therefore mainly addressed to their conservation and maintenance.
Masonry vaults present different static behavior according to their geometry, masonry strength, constructional techniques, and so forth. Stability of a broad class of masonry vaults depends upon the stone elements being held together by gravity and friction. Most vaults fall within this category and their static behavior is strongly conditioned by the low tensile masonry strength.
After some historical notes, of introductory character, the implemented approach to analyze statics of these masonry vaults is described in the first section of this chapter. Two different stress states can be detected: the initial state, without cracking, and the final cracked stress state, governed by the vanishing tensile strength. In the early stages of their lifetime vaults, in fact, behave as solid structures able to sustain tensile stresses: for them the membrane solution provides a reasonably static accurate description. The final state, occurring after cracking, will be conversely modeled within the framework of the no-tension masonry materials.
