Beam to Wall Anchorage Design

 Beam to Wall Anchorage Design

Through funding from the Structural Engineers Association of Northern California, initial testing at Scientific Construction Laboratories Inc. confirmed the need to comply with Appendix D requirements to prevent plastic hinging at anchor locations (D.3.3.2).Follow-on testing at the Simpson Strong-Tie Tyrell Gilb Research Laboratory was then used to confirm these findings and validate performance. 

 

The testing consisted of specimens with closed tie anchor reinforcement, non-closed u-stirrups and control specimens without anchor reinforcement. Flexural and shear reinforcement were designed to resist Appendix D amplified anchorage forces and compared to test beams designed for non-amplified strength level forces.
