Consider the coverplate beam bolted connection shown in gure

Consider the cover-plate beam, bolted connection shown in gures. P is 700 kips and there are two lines of two bolts in each flange.

Under what circumstances can we assume each bolt carries an equal portion of the load?

Problem #6: Bolted Connection Consider the cover-plate beam, bolted connection shown in gures. P is 700 kips and there are two lines of two bolts in each flange. P/2 18 in 3in 14 in a) Under what circumstances can we assume each bolt carries an equal portion of the load? O (1) The bolts are round O (2) The bolts are placed symmetrically (3) The connection is not subject to bending (4) All of the above (5) Option 2 and 3 are necessary

Solution

The connection should not be subjected to bending otherwise bolts above the neutral axis will be in tension and bolts below

The neutral axis will be in compression.Hence they will not share equal load.

The bolts should be placed symmetrically so that the eccentricity in the connection becomes zero. Hence the bolts will share equal load.

Hence option 5 is correct.
