Through bolt in wood
Through bolt in wood
(OP)
Is a through bolt (5/8") technically a dowel-type fastener? Meaning can we use Chapter 11 of the 2012 NDS to calculate shear/withdrawal capacities for it? Im talking about something like this:
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Chapter 11, Mechanical Connections, may have some requirements that need to be considered.
Chapter 12, Dowel-Type Fasteners, has detailing requirements and covers the lateral (shear) design
For tension, the bolt strength typically doesn't govern but should be checked (often times OK by inspection). The bearing perpendicular to grain needs to be checked per chapter 3, Design Provisions and Equations, along with the material chapter (EG chapter 4 for sawn lumber, chapter 5 for glulams etc). The area of the washer is used as the bearing area, don't count the bolt-hole in the washer in the bearing area.
