Masonry Infill Wall

In the seismic codes, lateral rigidity and strength of infill panels are ignored in the design. However recent earthquakes occurred in the world has shown that infill walls change the dynamic behavior of the frame. In this article we propose to investigate the effect of infill wall on the seismic behavior of framed concrete buildings. For this purpose, a framed reinforced concrete building is considered. An equivalent diagonal strut model is used for masonry infill. The strut properties are calculated according to the FEMA306 [7]. Nonlinear pushover analysis is used to assess the seismic behavior. The results show that introduction of the masonry infill wall in the analysis modifies the behavior of bare frame. There is a drastic change in the bending moments and shear forces. The modeling of infill wall transforms the rigid frame into braced frame.
