Summary:
BDTM.106 - Overhead Adhesive Anchor Sustained Tensile Load
For quite a few years, largely due to the Boston Tunnel ceiling collapse in 2006, engineers have been advised to avoid installing adhesive anchor bolts for overhead applications where the anchor will see sustained tensile loads. This BDTM officially documents a policy prohibiting such installations for LA DOTD structures.
This email notification and BDTM are distributed to all DOTD in-house and consultant bridge designers.
This email notification is copied to those copied on the BDTM, and to Consultant Contracts Services staff in order to distribute the e-mail and BDTM to consultant firms on the DOTD solicitation list. If you are listed as the Principle-In-Charge for a consultant firm, please inform your design staff of this BDTM.
Thank you.
