Influence of Adhered Masonry façade on Seismic Response of Buildings

Observations obtained in the course of previous earthquakes and studies performed by different researchers indicate the influence of cladding (façade) on seismic performance of structure. there is a dearth of technical knowledge in this field and no proper understanding exists of the actual response...
