One of the large companies designing wood trusses in this country is Alpine Engineered Products. The trusses in the picture were designed by them and then manufactured by a local lumber company that we use. Along with the set of engineered drawings comes some general information about bracing trusses. Because every situation is so different it’s up to the builder to understand the concepts and apply them correctly. Many times when a collapse has occurred the investigation reveals a lack of proper bracing.
Alpine Engineered Products publishes a great Builders Guide To Trusses. The guide has lots of information for builders about proper handling, connections, reading the drawings and bracing. One of the more important bracing issues is properly bracing the gable ends and then connecting that bracing to the laterals along the length of the building. The other important bracing is web braces that are actually detailed and called out on the drawings. Again the Builders Guide To Trusses is a big help understanding how that works.
So next time you’re involved with the erection of wood trusses or you’re having a new home built with trusses make sure that the trusses are properly braced.

Heavy timber trusses require that crane also.....we see lots of timber frame great rooms with conventional framing for the remainder. Do you guys run into that? Have a good day.
Yes heavy timber trusses are becoming very popular around here for folks that want that "Adirondack" style home.
