| Summary: | Present study summarizes an overview on the available experimental and practical data and results from laboratory testing (ungrouted and grouted) three leaf masonry wallettes in compression and in diagonal compression. On the basis of the experimental results, (A) the structural behavior of the multiple leaf-masonry walls studied in details (b) the parameters that affect the behavior of ungrouted masonry are detected and commented upon, and (c) the behavior of grouted masonry studied in details. Particularly attention to be paid to large walls whose construction may comprise different kinds of materials. Such walls include cavity walls; rubble filled masonry walls and veneered brick walls which have poor quality core. Not only may the interior of the wall be less capable of carrying load but movement of the core material may also be a source of new stresses. As the experimental results show that the key parameter for the improvement of the mechanical properties of masonry is not the compressive strength of the injected grout, emphasis is given to ternary, as well as to hydraulic lime based grouts: those materials are expected to ensure durable interventions, they lead to a significant enhancement of the mechanical properties of masonry. On the basis of the experimental data on wallettes, as well as based on recent data from tests on grouted cylinders made of filling materials, simple formulae are drived, allowing for the strength of masonry to be calculated, and scientifically interventions processes and techniques had been applied to selected historical monuments in Cairo. |
