Residual shear strength of a soil represents the lowest possible shear strength that a soil exhibits at large shear strains and this mobilized strength plays a significant role in the stability analyses. A slope does not fail if the applied shear stress is less than the residual shear strength (Gilbert et al. 2005).

If shear reinforcement is provided, the concrete contribution to shear strength in a reinforced concrete member is a function of both the aggregate interlock and the dowel action between the concrete and reinforcement. Once a shear crack forms, the shear reinforcement engages, providing the remaining shear capacity of the section V s. For

the ASTM D 4255/D 4255M The standard test method for in-plane shear properties of polymer matrix composite materials by the rail shear method. For the latter, however, a modified design of the three-rail shear test, as proposed by the authors in Ref. 22 is used. The authors have already modelled the nonlinear shear stress–strain behavior of a glass fibre-reinforced epoxy, by performing [þ .

solutions to the theory of elasticity. The second approach is to use the shear correction factor to account for the di erence between the average shear or shear strain and the actual shear or shear strain using exact solutions to the theory of elasticity. Timoshenko(1922) originated the frequency-matching approach. He calculated the

modes of unstiffened beam-to-column web shear tabs. On the other hand, she determined that shear plate buckling is the governing failure mode in stiffened beam-to-column web shear tabs. Baldwin-Metzger (2006) tested four beam-to-column flange extended shear tabs. These connections failed due to weld tearing and/or beam failure.

The CAN/CSA S16-01 seismic design process for steel plate shear walls follows the selection of a lateral load resisting system (i.e., shear walls with rigid or flexible beam-to-column connections), calculation of the appropriate design base shear, and distribution of that base shear along the building height by the usual
