The load carried by splice = total load÷2.
Rivet value = 0.785*26*26*90 = 47.78KN,
Number of rivet = 400÷47.78 = 8.37.
= 9 rivets.
Rivet value = 0.785*26*26*90 = 47.78KN,
Number of rivet = 400÷47.78 = 8.37.
= 9 rivets.

In this case, flat will be in double shear and assume power driven shop rivets.
Thickness of 400 ISF=12mm(assume)
Shearing strength=2*3.14*26^2*100/4/1000=106.22kn,
Bearing strength=300*26*12/1000=93.6kn,
Rivet value=min(106.22,93.6)=93.6kn,
No of rivets=800/93.6=8.54=9,
Hence correct answer is D.

80000/dt,
80000/ 400*26.
80000/ 400*26.

Can anyone give the correct solution, please?

Number of rivets= sf/area=40001/(3.14*26^2/4)=8.

No. of rivets = load/rivet value.
load=800kn.
The rivet value=shear strength of rivet= (3.14(26)^2x(100/1000))/4.
load=800kn.
The rivet value=shear strength of rivet= (3.14(26)^2x(100/1000))/4.
