Nominal shear strength


"Currently, there are five equations for the nominal shear strength of a screw connection given in the American Iron and Steel Institute’s Specification for the Design of Cold-Formed Steel Structural Members (2001). In an effort to increase the accuracy of the nominal shear equations, studies at the Department of Civil Engineering at the University of Sydney-Australia led to the development of a varied form of strength equations (Rogers and Hancock, 1997).

This research analyzes six different sets of data using the AISI equations and the equations developed by the University of Sydney to determine if these new equations will in fact increase the accuracy of the computed nominal shear strength as compared to the tested shear strength.

As a result of the data analysis, the current AISI equation E4.3.1-1 for t2/t1 < 1.0 is conservative.

For t2/t1 > 1.00, normal ductility and within seven screw connections the Rogers and Hancock equation is more accurate prediction of the connection strength.

For more than seven screws in a connection, use the Rogers and Hancock equation with a reduction factor R of 0.85 provided satisfactory estimates of the connection strength"--Abstract, page iii.
