CONNECTIONS: Eccentric Shear
Eccentric Shear is characterized as an in-plane loading condition in which the
line of action of the applied loading resultant does not coincide with the center
of gravity for the connection bolt group.

From a consideration of global equilibrium, we know the internal member
shear to be constant, and of the value p e (see left portion of Figure (1).

Consider the composite column drawn below. It will be an exterior member
in the top-most story of a high-rise framing system, and it will support a
continuously attached faade wall; which will induce the uniformly distributed
traction drawn below.
