Re: Heavy Timber Truss Connections

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Paul,
 
Are you having difficulties with a certain type of configuration?  Normally, I find that the heel connections will control on a typical high-load timber truss.  One option to limit bolts in the top chord at the heel is the use of a thrust plate at the end of the top chord (won't work if you need tails to be exposed).  I have used this in both knife plate and side plate applications.    I know that there are some propreitary timber connections with some of the high end timber manufacturing companies. 
 
Another way to solve heel problems is to have a raised heel (like a stubbed truss) which will allow a web to deliver the load to the heel area at a better angle than the typical scarf cut angle.
 
Maybe some more info on your particular problem?

Subject: Heavy Timber Truss Connections

I am looking for alternate truss connection types for heavy timber trusses.  Looking for ideas mainly, different connections and methods, chord and web configurations, etc.  I have some exposed heavy timber trusses to design, different geometries for different locations in the project, and I know the connections are going to control the design.
 
Any input is appreciated.
 
Thanks,
