The past review works show preference of steel structures over RCC structures due to ease on fabrication, lesser weight
and better ductility which enhances seismic performance of these structures. The review of previous steel codes shows that beam
column connections are assumed to be rigid. However, in reality beam – column connections do passes some degree of flexibility
which needs to be incorporated in formulating the seismic design methodologies for the steel sections. In this research work an
effort has been made to study the effect of beam – column connections on seismic response. The steel building frames ranging
from 5 storey to 10 storey height has been selected for the analytical study. The connection flexibility has been varied in these
building frames and these frames have been subjected to an ensemble of 100 ground motions to determine the seismic response.
The seismic response has been studies in terms of response parameters like storey shear, storey moment, storey drift.
