Masonry-infilled reinforced concrete frames represent a very common construction typology across the Mediterranean countries. The presence of infills substantially modifies global seismic performances buildings in terms strength, stiffness, and energy dissipation. Although several research studies focused on overall infilled frames, modeling infill panels remains an open issue due to complex in...

Abstract Fabric reinforced cementitious matrix (FRCM) composites, also known as textile mortars (TRM), an inorganic constituting fibre fabrics and cement-based mortar, are becoming a widely used composite material in Europe for upgrading the seismic resistance of existing concrete (RC) frame buildings. One way providing is through application proposed FRCM system on masonry infill walls to incr...

Since the establishment of ASTM standard C91, masonry cement mortars have become widely used for masonry construction in low to moderate seismic regions. However, the Masonry Standards Joint Committee Code prohibits the use of masonry cement mortars in lateral force resisting systems for structures that fall into Seismic Design Categories D, E, and F. The general objective of this study is to e...

Brick masonry veneer walls connected to infill inserted in a reinforced concrete (RC) frame are common constructive system Portugal. The stability of the wall is ensured by ties that make connection with walls. These enable transferring out-of-plane loads main structure due wind, and particularly earthquakes. However, characterization seismic behavior these tie connections an insufficiently exp...

• A two-dimensional mesoscale lattice modeling approach for infill walls is proposed. Two tests were conducted aerated autoclaved concrete (AAC) infilled with and without openings. Modeling was validated the test results. Infill contact length found to depend on deformation levels. Significant wall damage in reinforced frame buildings observed past earthquakes. vast number of numerical approach...

Masonry has low cohesive strength and is susceptible to the brittle failure, when subjected to induced tensile stresses. It fails due to lateral tensile stresses even when masonry prisms are tested in uni-axial static compression and the stress-strain curve remains almost linear up to failure. Although masonry normally resists compressive forces, under lateral in-plane cyclic loads some parts o...
