Section 10.3

Shear Strength

Last Revised: 11/04/2014

Since the concrete does not contribute to the shear strength of the composite beam, SCM I4.2 states that "The available shear strength ... shall be determined based upon the properties of the steel section alone in accordance with Chapter G."  While the section addresses composite beams with steel deck, it the only section which looks at shear in composite beams.  It is consistent with past practice to apply SCM G to the computation of shear capacity in composite beams.

The computation of shear strength was discussed BGSCM 8.3.2.
