Case studies for existing buildings with blind walls

Abstract

The blind walls, arranged between the neighboring buildings, are at the same time structural walls for the buildings from the typological groups analyzed in this paper. The foundations we can find in these are in 95% of cases continuous, surface foundations: stone or brick masonry; simple, unreinforced concrete (due to the knowledge from the respective historical moment) or reinforced concrete. Depending on the type of floor and the materials used, there may be: flexible floors, which do not have a horizontal diaphragm behavior (rigid and resistant washer), specific to floors with unidirectional discharge or rigid and resistant floors, which have a horizontal diaphragm behavior (rigid and resistant washer), specific to monolithic floors in RC.; Regardless of the type of floors that are discharged at the turbocharged walls, it is observed that, at most, there are discharges only on one side of the turbines, and not on both sides as on the structural walls inside the buildings. These aspects must be taken into account even if, through the safety measures and methods, the turban walls end up passing from type 1 to type 2, with the unloading of the floors.
