Simplified methodologies for out-of-plane resistance verification of framed-masonry walls

In design for earthquake resistance of reinforced concrete frame structures, unreinforced masonry (URM) infill walls, panels or partitions are considered as non-structural elements. However, if effective structural contact with the frame is such that the infill and frame will have equal deformations (framed-masonry), masonry infill walls should be considered as integrated in the structure and a part of the seismic earthquake system (structural element). The effects of infill walls, with or without openings, on the overall seismic response of structural frames are manifested through increase in stiffness, strength and energy dissipation capacity and the alteration of earthquake resistance distribution throughout the structure. The field of research is divided into three general fields: in-plane response, out-of-plane response and their combinations. This work presents the state of the art of simplified modelling approaches for out-of-plane resistance verification. A parametric study was conducted to address the sensitivity of simplified mathematical models on the structural characteristics of masonry infill walls.
