Abstract:

Use larch dimension lumber from China and imported truss plates to manufacture truss plate connection, and test the tension properties of the connection. The testing result point out that larch dimension lumber from China can take the place of SYP to manufacture timer truss. Three new truss plates were designed, which used domestic zinc coated steel. Test the behavior of domestic truss plate. The testing result point out that domestic truss plate meet the requirement of volume production, and new designs can advance the performance of truss plate connection. But domestic truss plate need to adjust the processing technic, then can use in actual production.

Key words: domestic timer truss, truss plate design, truss plate detection
