Concrete Anchor Design: cast in headed bolt
CIHB 750 01 to CIHB 875 01
Concrete anchor design data per ACI 318-19 Chapter 17. Covers cast-in and post-installed anchor types: cast-in headed bolt (F1554 Gr.36/55/105), cast-in J-bolt, cast-in headed stud (AWS/A108), expansion wedge anchor, expansion sleeve anchor, undercut anchor, adhesive threaded rod (AC308), adhesive rebar, and concrete screw anchor. Fields include nominal diameter, effective embedment hef, effective stress area Ase, bearing area Abrg, steel tensile strength Nsa, shear strength Vsa, concrete breakout Nb at f'c=4000 psi (kc=24 cast-in, kc=17 post-installed), pullout Np, critical edge distance cac, critical spacing, minimum member thickness, installation torque, phi factors for tension and shear, and seismic qualification.
