Masonry arches

The third part of a structural analysis, the analysis of safety, is normal carried out using only very simple techniques, as we shall see in Chapter 4. Ii recent series of papers on the analysis of masonry arches, Heyman [14] 1 pointed out the more general use of the plastic theorems of collapse and, particular, the Safe Theorem. In fact, tliis theorem effectively states that i. reasonable system of forces can be found to satisfy both the equilibrii... 

An interesting example of the strengthening of masonry buildings is the structural adjustment of the Monastery of Santa Chiara in Naples, realized with the use of FRP fabrics in order to enhance the mechanical strength of masonry arches, as shown in Figs. 10.9 and 10.10.

At the beginning of this chapter the craft origins of construction work was mentioned. The craft was dominated by rules of thumb , usually based upon Euclidean geometry. This worked well since large masonry structures were stable because of their shape, and since stresses were low. As long as the thrust line of the arch was inside the structure, the structure stood, and suitable structural shapes could be found by trial and error. Several functions were often...

The church is designed as a massive masonry stmcture constracted of different types of stone in cement lime mortar (PS state). The main structural elements are the domes, the arches, the vaults, the wooden floor structures, the columns, the walls and the foundation. In order to decide on the mix design for the cement lime mortar based on the analysis of the church, three options have been adopted for it ... 

Another well-known tower, the Washington Monument, was completed in 1884. At 555 feet in height, it was the world s tallest tower until the Eiffel Tower, nearly 1,000 feet tail, was completed in 1889. The Washington Monument remains the world s tallest masonry structure. The Gateway Arch in St. Louis, Missouri, is the tallest monument in the United States, at 630 feet...
