Abstract:
An experimental campaign on joints of x-braced frames is presented. Tests are performed on strap-gusset joints and lower and upper corner joints. Many different phenomena and failure modes are observed in these tests. However, it is possible to see that only one failure mode can be accepted if a good seismic performance of the frame needs to be guaranteed: the net-section failure of the diagonal strap after yielding. The results of the tests also allow to establish a set of recommendations for seismic design of joints. The effectiveness of these recommendations is verified by means of two final tests on complete x-braced frames. A full explanation on the behaviour of the joints and frames tested is included, together with a description of the special test set-up developed for the experimental campaign.
