Experimental testing of joints for seismic design of lightweight structures. Part 3: Gussets, corner...

July 2007 · Thin-Walled Structures

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 ... [Show full abstract] 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.

February 2006 · Thin-Walled Structures

Connections in x-braced shear walls play a crucial role in the seismic performance of lightweight structures: they should be strong enough to allow energy dissipation via plastification of the diagonal straps. An extensive experimental research on tensile screwed joints between straps is reported here. Two dominant failure modes are identified: (1) tilting and net section failure (T+NSF) and (2) ... [Show full abstract] tilting, bearing and pull out (T+B+PO). The analysis in terms of strength and ductility shows that T+NSF joints are suitable for seismic design, because the straps yield before the connections fail. T+B+PO joints, on the contrary, are not suited because the connection fails before the straps can yield. The influence of various design parameters (strap thickness, number and diameter of screws, steel grade) in the failure mode is studied, and design criteria to induce a T+NSF response are given.

June 2006 · Thin-Walled Structures

An experimental testing campaign on tensile bolted joints between straps is reported. Two dominant failure modes are identified: (1) tilting, bearing and tearing of the sheets (TS) and (2) tilting, bearing and net-section failure (NSF). The analysis in terms of ductility and strength shows that bolted connections are less adequate than screwed connections (reported in Part 1 of this paper) for ... [Show full abstract] the seismic design of X-braced shear walls in lightweight structures. NSF joints are more ductile than TS joints in the sense that they undergo larger displacements before failure. However, if washers are not used, both types of connections fail before energy dissipation through yielding of the diagonal straps can occur. Some design recommendations to improve the seismic performance of bolted joints, including the use of washers, are given. The accuracy of Eurocode 3 formulas to predict the ultimate load is also analyzed. Peer Reviewed Postprint (author’s final draft)
