A double lap splice connection shown in figure B is made up of 6mm x 150mm and 9mm x 150mm. Use NSCP specifications and assume a double row of bolts with standard size holes for a bearing type connection with threads excluded from the shear planes. Minimum tensile strength Fu = 552.93MPa. Assume diameter hole is 3mm bigger than the diameter of bolts. Allowable shear stress is Fv = 207MPa. Allowable bearing stress fb = 1.2Fu. Diameter of bolts is 19mm. Fy = 449.25MPa. (a) Compute the tensile capacity of the steel plates. (Max. Net Area = 0.85 of Gross Area) (b) Compute the number of 19mm diameter bolts to develop the full strength of the plates.

Question
A double lap splice connection shown in figure B is made up of 6mm x 150mm and
9mm x 150mm. Use NSCP specifications and assume a double row of bolts with standard
size holes for a bearing type connection with threads excluded from the shear planes.
Minimum tensile strength Fu = 552.93MPa. Assume diameter hole is 3mm bigger than the
diameter of bolts. Allowable shear stress is Fv = 207MPa. Allowable bearing stress fb = 1.2Fu.
Diameter of bolts is 19mm. Fy = 449.25MPa.
(a) Compute the tensile capacity of the steel plates. (Max. Net Area = 0.85 of Gross Area)
(b) Compute the number of 19mm diameter bolts to develop the full strength of the plates.
Note: SHOW DRAWINGS AND SOLUTIONS.
