Design of Tension members Precautions
In axially loaded tension members the stresses are uniformly distributed over the cross section and for a given allowable stress the area of the member can be determined.
In calculating tension members the net area of the section is considered .
to avoid excessive deduction ,the diameter of the rivet must not be too long big , and if there is more than one gauge line , the rivets must be stagger Deduction of one rivet hole only Stagger rivets.
The net area shall be the least than can be determined from any plane cutting the section perpendicularly to its axis diagonally or following a zig-zag line through adjacent rivet holes .
In each case all rivet holes met with shall be deducted from the gross sectional area , where any portion of the sectional area is measured along a diagonal plane , 0.8 only of the net area of such portion shall be taken in computing the effective area with a minimum equal to that obtained by assuming all the holes to be in one perpendicular plane .
