What is eccentric shear”(a) shear effects caused by concentric load on a bolt group(b) shear effects caused by eccentric load on a bolt group(c) shear effects caused by moment on a bolt group(d) shear effects caused by torsion load on a bolt groupThis question was addressed to me during a job interview.My doubt is from Moment Resistant & Beam-to-Beam Connections in portion Bolted Connections of Design of Steel Structures

Answer»

Correct option is (B) SHEAR effects caused by eccentric load on a bolt group

Easy explanation: When bolt groups are subjected to shear and MOMENT in shear plane, the load that is eccentric is eccentric with RESPECT to centroid of bolt group can be replaced with a force acting through the centroid of bolt group and a moment (Magnitude = Pe). Both the moment and the force RESULT in shear effects in the bolts of the group and is called as eccentric shear.
