The average value of [f.sub.b,ult] was 136 ksi and 151 ksi, for common nails and cooler nails, respectively.Simplified Shear Design of Structural Concrete MembersA-2 Interface shear transfer: Local roughness in the crack plane provides resistance against slip and thus there is shear transfer across shear cracks. The contribution of interface shear transfer to shear strength is a function of the crack width and aggregate size.

The criterion that defines the start of dowel action contribution is given by Mazars' damage approach. Figure 5.5 presents the application of this damage criterion in the modeling of dowel action contribution.See all results for this questionHow does the dowel action increase shear strength?The dowel action can increase significantly the structural shear strength as well as the post-peak ductility of some structural elements, such as beams with few or no shear reinforcements. In the proposed nonlinear model, reinforcements are modeled as beams over an elastic foundation composed by concrete.See all results for this question

In joints with dowel-type fasteners, such as nails and screws, the fastener is fractured under reversed cyclic loading (e.g., seismic force), reducing the ductility of the joint. The fracture is caused by low-cycle fatigue due to the reversed cyclic bending of the fastener.
