steel plate timber connector
steel plate timber connector
(OP)
I am engineering a log house with a large covered porch. The porch roof is supported by 12x12 timber posts, which supports a 10x12 timber header laid flatwise. I need to created a moment connection between the post and header for lateral resistance, but can not use knee bracing (per architect). I would like to bolt or lag a steel "T" plate onto the connection, but am not sure how to engineer the plate.
My thoughts are to model the plate as a steel beam approximately 1/4" thick x 8" wide and two feet long (two feet is approximate center to center distance of bolt patterns). I know the model works for pure bending, shear, etc., but how do I address lateral torsional buckling? Do I assume that since the plate is lagged to the post and header that it is sufficiently laterally braced, and just not worry about LTB?
Thanks for you help,
Alex

Here are references (free .pdf downloads) that may be of interest
"Designing For Lateral-Torsional Stability In Wood Members, Technical Report 14"

About the moment-resisting connection - a typical (manufactured) Tee adds stiffness to a joint, but in not normally considered a moment-resisting connection.
For reference, suggest you download the TECO Timber Connector Catalog (see page 42 for their Tees) & the TECO Design Manual at this link

However, your proposed "custom made" Tee sounds like that it has the potential to meet your requirements.

So I really only have the option of placing the rigid connection at the top.
