Typical extended end-plate connections used in moment resisting steel
frames with Hollow Structural Section (HSS) columns will generally exh
ibit a certain degree of flexibility. The actual response of such fram
es cannot be realistically assessed, unless the connection flexibility
is incorporated in the analysis. This requires the development of mom
ent-rotation relationships capable of representing connection response
. The objective of this work is to develop an analytical model for suc
h connections capable of simulating its behaviour in terms of its mome
nt-rotation relationship, so that it can be used in the determination
of the overall frame response. The model evaluates the main connection
parameters such as its initial stiffness and plastic moment capacity
on the basis of few secondary parameters obtained from test results. T
he HSS column flange is modelled on both the tension and the compressi
on sides of the connection because of its major contribution to the co
nnection's rotation. The accuracy of the analytical model was examined
by comparing the model results with experimental measurements, it was
found that the model predicts the connection rotation with reasonable
accuracy at different levels of loading, A numerical example is provi
ded to illustrate how the connection model can be applied in design. (
