Let Strength of each bolt = 100KN.
I. Critical state of 1st sec= (600/100) = 6.
--->600KN.
II. Critical state of 2nd sec = (600-100/100+100) = 2.5.
(since 100KN load is taken by 1st bolt, net load transferred to second section = 600-100).
III. Critical state of 3rd sec = (500-200/100+100+100) = 1.
Critical condition of a bolt = (load applied/strength of bolt.
Hence first section is critical section (6>2. 5>1).
I. Critical state of 1st sec= (600/100) = 6.
--->600KN.
II. Critical state of 2nd sec = (600-100/100+100) = 2.5.
(since 100KN load is taken by 1st bolt, net load transferred to second section = 600-100).
III. Critical state of 3rd sec = (500-200/100+100+100) = 1.
Critical condition of a bolt = (load applied/strength of bolt.
Hence first section is critical section (6>2. 5>1).

Suppose there is 6 bolt.
1 in the first row, 2 in the second row and 3 in the last row.
For the first row, strength is due to the net sectional area and one rivet.
For second row strength is due to the net sectional area and 3 rivet 1 from the first row and 2 from other rows.
For the third row, strength is due to the net sectional area and 6 rivet.
But net sectional area1> 2 >3.
1 in the first row, 2 in the second row and 3 in the last row.
For the first row, strength is due to the net sectional area and one rivet.
For second row strength is due to the net sectional area and 3 rivet 1 from the first row and 2 from other rows.
For the third row, strength is due to the net sectional area and 6 rivet.
But net sectional area1> 2 >3.

There is border of the diamond rivet that mean it's the first row at that point maxi. Shear stress occurs, so it's the weakest point of the diamond rivet is the first row.
Ram said:

Section in first row is weakest because shear strength in first row is of only. 1 Rivet and in second row shear strength is of 2 rivets and further increasing.

Weakest section in riveting at which maximum stress are developed and in a diamond riveting, it is first row.

Anyone have link to explain this diamond rivet entering first row? Picture or video.
