Mm-hmm.
6:09
And, uh, we had already identical samples, uh, made, uh, uh, made with the same weld profiles, but they're tested under static ones.
6:20
So in this research, we are going to compare the result, test results from cyclic ones with static ones, and the main goal is that to understand what is the weld failure in these samples when, uh, we are, uh, introducing cyclic strain hardening around the weld.
6:39
Uh, yeah, an- another research that we have, uh, the second one is effect of ancillary weld details on seismic connections performance, and in this research, uh, our another student, Dinesh, is working.
6:53
He's going to test a few large-scale moment end plate connections made with access hole and without access hole.
7:02
So we know that the shape of access hole in American standard is costly, and sometimes it's not practical to be fabricated.
7:12
So we are going to check that, uh, it's possible to use a simple shape for the access hole, and also even more, we want to see that we can, uh, eliminate using access hole for complete penetration butt welds or not.

Um, you know, where, where does industry uptake really come into play here? Uh, how does a fabricator engineer end up doing something differently because of this program?
