timber diagonals for wall bracing - tension/compression?

[n3jc]

Hello,

I am looking at timber frame rsidental buildings and I have a question about designing of wall bracing - diagonals:
are this diagonals designed to carry only in compression or both? comression + tension?

In case of seismic forces we can get large compression/tension forces in diagonals - depending of the direction of earthquake.
Lets say we get a large tension force in diagonal (above 50 kN). Im pretty sure there is a problem how to design joints at the end of this diagonal.
So by this in mind it is more logical to desing them only in compression.
I am not worried with anchoring members in tension to the foundations but more
about the tension joints between timber elements.
How would you approach this?

Thank you for reply.

Well if you've got two diagonals with one in each orientation, then at least one will be acting in compression.

Due to the issue with connections like you indicated, I've always just assumed them to act in compression. Similar to how I always assume steel angle diagonals to be tension only.

It's easier to connect for compression loads in wood construction.
