Mechanical behaviour of historic masonry structures strengthened by bed joints structural repointing

Welded, sandblasted, stainless steel corrugated bars in non-carbonated and carbonated mortars: A 9-year corrosion study

“…However. tests in alkaline solutions have pointed out that welding 1 can decrease the corrosion resistance of stainless steels [10][11][12][13][14][15][16][17]. Previous research carried out in simulated pore solutions suggests that the adverse effect of weldings can be more or less marked depending on the stainless steel grade: more alloyed stainless steels seem to be less welding-sensitive [17].…”

“…Moreover. stainless steel corrugated bars are also used to repair corroded structures, as replacements of old, damaged CS bars [13,14). When stainless steel bars are employed to replace part of corroded CS bars, it is sometimes unavoidable to weld the stainless steel reinforcements to the rest of the structure.…”

Limit Analysis Approach for the Seismic Vulnerability Reduction of Masonry Towers Through Strengthening With Traditional and Innovative Materials

“…As a matter of fact, their structural behavior is quite complex and their retrofitting is a difficult task, mainly when dealing with cultural heritage preservation. For instance, some proposed retrofitting techniques in the literature consist of: horizontal high-strength bars [25], pre-stressed vertical tie rods [14], viscous dampers at the base [26], intrados FRP sheets [18], masonry material properties upgrading [27]. The efficiency of any retrofitting technique is primarily related to the expected failure mechanism and the strictness of the implementation.…”

Performance of Masonry Structur -Review

“…Maria Rosa Valluzzi et al, (2005) this paper is to determine the mechanical behaviour of brick masonry structures subjected to overloading phenomena is presented. That type of structures suffers a very specific damage, represented by diffused thin cracks, which can lead to a sudden collapse.…”
