This paper is a summary of an investigation into the cyclic response of a steel cruciform joint. A star plate beam to column joint identical to one of those forming the frame of the pier structure at Auckland International Airport was tested at the University of Auckland, School of Engineering. In this paper both the preparations undertaken and the subsequent experimental programme are described. The results are analysed and the observed behaviour is discussed. Comparisons are made with recently proposed design criteria for steel beam to column connections, as well as with formulae for predicting the load-deflection curves. Conclusions are drawn on the suitability of these theories for response prediction of star plate geometry joints. Additionally the energy absorption capabilities of the joint are compared with results from earlier American research.
