The presence of infill panels in buildings with concrete or steel frames can lead to conflicting effects on the structural response, depending on the mechanical properties, the geometrical distribution of infills and the interaction with structural elements. Traditionally, the infill walls are integrated with the structural frame. This could possibly lead to significant degradation of stiffness and strength under Strong earthquakes. This paper presents three methods previously proposed and validated by other researchers. Each of these methods has its own system and technique. However, all of them have the same main concept (allowing infill wall–frame interaction under wind loading and minor-to-moderate earthquakes for reduced building drift but disengaging them under damaging events). Each method is adequately explained with summary of its main results. Finally, a comparison of them (including several comparison factors: improved characteristics, preferred infill material, difficulty level of manufacturing and installation, cost, extent of damage under damaging events, etc.) is presented.
