The effect of infill walls to stiffness of the structures has been known for a long time and this effect has taken many of the earthquake regulations with empirical relationships and equations into account. However, in strength-based calculations, buildings are taken as bare frames and infill walls are effected as vertical load to system, whereas infill walls contribute to stiffness at the beginning of the earthquake and help meet seismic loads by incurring damage during an earthquake.
