The construction of reinforced concrete buildings w
ith unreinforced infill is common practice even in seismically active country such as Bhutan, which is located in high seismic region of Eastern Himalaya. All buildings c onstructed prior 1998 were constructed without seismic provisions while those constructed after this period adopted seismic codes of neighbouring country, India. However, the codes have limited information on the design of infilled struc tures besides having differences in architectural requirements which may compound the structural problems. Although the influence of infill on the reinforced concrete framed structures is known, thepresent seismic codes do not consider it due to the lack of sufficient information.Time history analyses were performed to study the influence of infill on the performance of concrete framed structures. Important parameters were considered and
the results presented in a manner that can be used
by practitioners. The results show that the influence of infill on the structural performance is significant. The structural responses such as funda mental period, roof displacement,
inter-storey drift ratio, stresses in infill wall a
nd structural member forces of beams
and column generally reduce, with incorporation of
infill wall. The structures designed and constructed with or without seismic provision perform in a similar manner if the infills of high strength are used.
