z c) Bolted end-plate connection with only one bolt-row active in tension

In line with the mid-thickness of the compression flange

Distance from the centre of compression to the bolt-row in tension

d) Bolted extended end-plate connection with only two bolt-rows active in tension

In line with the mid-thickness of the compression flange

Conservatively z may be taken as the distance from the centre of compression to a point midway between these two bolt-rows e) Other bolted end-plate connections with two or more bolt-rows in tension

In line with the mid-thickness of the compression flange

An approximate value may be obtained by taking the distance from the centre of compression to a point midway between the farthest two bolt-rows in tension

A more accurate value may be determined by taking the lever arm z as equal to zeq obtained using the method given in 6.3.3.1.
