ANCHOR BOLT DESIGN
In accordance with ACI318-11
Tedds calculation version 2.0.1
Anchor bolt geometry
Type of anchor bolt; Cast-in headed end bolt anchor
Diameter of anchor bolt; da= 25 mm
Number of bolts in x direction; Nboltx= 2
Number of bolts in y direction; Nbolty= 2
Total number of bolts; ntotal= (Nboltx2) + (Nbolty- 2) 2 = 4
Total number of bolts in tension; ntens= N boltN= 0
Spacing of bolts in x direction; sboltx= 330mm
Spacing of bolts in y direction; sbolty= 432mm
Number of threads per inch; nt= 8
Effective cross-sectional area of anchor; Ase= / 4 (da- 0.9743 in / nt)2= 391mm2
Embedded depth of each anchor bolt; hef= 203mm
Material details
Minimum yield strength of steel; fya= 248.2N/mm2
Nominal tensile strength of steel; futa= 471.6N/mm2
Compressive strength of concrete; fc= 21 N/mm2
Concrete modification factor; = 1.00
