22.253kips

Explanation of Solution

Given:

Steel Design (Activate Learning with these NEW titles from Engineering!), Chapter 8, Problem 8.2.1P

Calculation:

Determine the direct shear components:

Px=35(15)=9kipsPy=45(15)=12kipsPcx=94=2.25kipsPcy=124=3kips

Eccentricity:

ex=12in.ey=9+1.54.5=6in.

M=9(6)+12(12)=198inkips (Clockwise)

(x2+y2)=2[(4.5)2+(1.5)2]=45in.2

Top bolt is critical.

x=0y=92=4.5in.pmx=My(x2+y2)=198(4.5)45=19.8kipspx=2.25+19.8=22.05kipspy=3kipsp=(px)2+(py)2=(22.05)2+(3)2=22.253kips

Conclusion:

The maximum bolt shear force in the given bracket connection is 22.253kips.
