Anchor Bolt Design

There were two major changes to the anchor bolt design provisions in the 2016 edition of TMS 402.  One change was to increase the calculated shear crushing strength by 67%.  The other change was to go from a linear interaction equation for combined bending and shear to an elliptical interaction equation.  This lesson covers the basis for these changes.  In addition to the changes in TMS 402, ASCE 7-16 reduced the required load increase for seismic applications when the anchor bolt failure is not yielding from 2.5 to 2.0.  The lesson also covers general anchor bolt design in masonry, provides practical design tips, and shows examples of anchor bolt design.

Learning Objectives:

• Understand the changes, and the basis for the changes, to anchor bolt design provisions in TMS 402.
• Understand the design of anchors bolts in tension.
• Understand the design of anchor bolts in shear.
• Understand the design of anchor bolts in combined tension and shear.
