Holding down bolts design
NettetThe resistance of a bolted end plate connection is provided by a combination of tension forces in the bolts adjacent to one flange and compression forces in bearing at the other flange. Unless there is axial force in the beam, the total tension and compression forces are equal and opposite. NettetThis video demonstrates the anchor bolt design within Tedds. You can choose from ACI 318R-08 and ACI 318R-05.
