Consideration <>f the forces on the rivets and the thick- 

 ness of flange and splice material shows that the shearing 

 value of the rivets is the determining one along the plane

Fig. 10 (/), (g) and (h) show the forces on the rivets 

 through the horizontal legs of the flange angles of the top 

 flange splice. It is readily seen that the number of rivets

Cover plate splices should be located so that a simple 

 lengthening of an outer cover plate will form the splice. 

 For example if a splice were required in the first cover
