Design data on gusset and flitch plates

Hello,<br>
<br>
Can someone recommend literature that contains design information, ie. moments, shear, etc., on steel gusset plates and flitch plates when applied to existing wood members.<br>
<br>
Thanks,<br>

Except the seller provides data I would calculate from first principles.

Nailing can give you what on tension and shear.

The gussets nowadays you can very well model in FEM for an initial imperfection then add P delta and if non large deflection it is not buckling.

Never was necessary so, it was customary use some width at the free edge if triangular and use K=0.75 for KL when checking for buckling. I is still current practice. Seating plates in bending you can dimension M/W or M/S or so.

ISHVAAG, To suggest modelling a gusset plate in FE is purely irresponsible. Moreover, it wasn't even suggested that there exist some imperfection in the existing gusset plate, yet you run on about imperfections and p-delta, why?! If you can't answer the question, then don't. I'm sure there will come an appropriate time or a question when you can plug your useful knowledge of finite elements and mathcad.

Qshake I am sorry to notice you may be a bit angry with me due to our different technical perceptions. I just comment what I think may be proper, not just exactly what is asked for, and I have seen others in the forum do the same. In this case tabulated data I can't provide, yet at least I indicate how I technically would proceed...of course more by K=0.75 than modelling imperfections...and in the end I think not such thing to deserve this a bit harsh comment. Humble that my knowledge may be, I must stand to it.

It saddens me a bit because I feel you really stand far more advanced than me in structural knowledge, and so I can't see very well why you feel uncozy on the use of off the shelf FEM for every application they may be used for...there are excellent modelling programs and they ease -as they can- much the burden of the structural designers, so I encourage its use for whichever the thing our imagination guides us.

The initial imperfection modelling thing for example, for a pony truss better than for this case, may be an expedient way of contrasting whichever tabulated info on the pony truss I have in another way, and to proceed to direct design/check of the members that in other way will be more cumbersome, er, inefficient...and precisely one of the things I am more interested in (see if 2 opinions coincide or not, and be efficient).

Have my best wishes in any case, Qshake.
