This paper proposes a generalised analytical model for examining connection response. The model is applied to the problem of welded double angle connections, as used by the UK offshore industry. The results of an experimental investigation into failure progression is also presented, and used to generate the spring constant values. Response in two directions was examined for three different geometry configurations. The work highlights the importance of angle outstand and it is hoped that the proposed connection model will be incorporated into a beam-connection model capable of predicting the response of a beam with semi-rigid supports, and the results of this work will be published in due course. © 2003 Elsevier Ltd.
