Re: Tension rod bracing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
A question to the group .

Has anybody seen or provided viscous dampers in conjunction with tension rod bracings
in single story / two story buildings ? Do you have any thoughts for or against this concept?
If tightness and lack of a dissipating mechanism is an issue, the dampers could serve
that purpose.

While I have limited experience in this subject, I will mention that one of the more impressive things I saw after the 1989 Loma Prieta earthquake here in the San Francisco area was a tall water tank with several of its bracing rods hanging loose from one end.  I wonder how well that structure would have performed if the eq., had lasted a little longer.  And it's right beside a major 6-lane city street.
