Shear strength, stiffness, and energy dissipation of walls with various aspect ratios were evaluated on the unit length basis, in terms of unit

shear load (v) (kN/m (kip/ft.

To illustrate the racking resistance of shear walls with the effective aspect ratios, the racking loads (F) were normalized by the effective wall length, and the subsequent analysis was based on unit

shear load (v) (kN/m (kip/ft.

The holes were located towards the slab supports to generate the maximum

shear load.

At the point of ult imate

shear load, therefore, the failure was likely initiated by a tensile failure in the weak Z-direction prior to the apparent shearing along the intended shear plane.

However, this assumes that the

shear load is distributed uniformly to the top of the wall, when in fact the

shear load is distributed according to stiffness.

For members under flexure and

shear load, the following simple formula for shear strength contribution of the concrete, (American Concrete Institute, 2007) is used (Equation 2):

With [beta] = 1, the yield forces between tensile and

shear load change in a linear way.

The IFF modes distinguish between matrix failure due to tension (Mode A), compression (Mode B) or combined compression and

shear load (Mode C) [3] (Figure 1).

Ultimate

shear load and failure modes were predicted by truss analogy approach.

Standard qualifications tests per ASTM D4161 require the joint to withstand a two times pressure class test and a partial vacuum both while in an angularly deflected alignment and under severe

shear load to assure an absolutely water tight joint.

The lowest stress could be observed in the ACL lateral fibers under tensile and

shear load.
