The nonlinear behaviour of connections employed in cold-formed thin-wa
lled structures are determined experimentally and a mathematical model
is developed to represent the connection behaviour. The generalized m
athematical model gives a close representation of the experimentally o
btained moment-rotation relationships for the connections investigated
. The moment-rotation relationships of all the connections investigate
d were found to be nonlinear. Copyright (C) 1996 Elsevier Science Ltd
