Single strap joint

For single-lap and single-strap joints calculate the maximum adhesive shear stress ... 

P(2) Compressively loaded double lap, double strap, supported single-lap, and supported single-strap joints shall be designed as the corresponding tensile loaded joint in respect of adhesive shear stresses. The load shall be taken as negative. 

P(2) In-plane loaded single-lap and single-strap joints shall be designed using the corresponding equations for tensile shear loaded Joints and using the parameter conversions indicated in Table 5.6. 

The procedure presented is valid for single-lap joints and it is assumed to be valid, with reasonable accuracy, for single-strap joints. 

The single-strap joint shown in Figure 5.43 is loaded by an in-plane (characteristic) tensile load per unit width of Pk=60 kN/m. The joint has the following thicknesses ti=tz=4 mm t=0.5 mm...

Figure 4 also shows that maximum loading densities of single-lap and single-strap joints are very close to each other. This is also true for double-lap and double-strap joints, as can be seen in Table 6. These results indicate that lap and strap joints may be treated using similar design principles and design procedures.

Variants of the strapped lap joint and the related double strapped lap joint are illustrated in Figure 2.33. The single strap joint is suitable only for light loads, since it is clearly prone to premature failure if subject to peel and cleavage forces.

In Sects. 24.2 and 24.3, analytical solutions for single lap joints are derived from the governing equations of Eqs. 24.9 and 24.20-24.21 for the linear and nonlinear overlaps. The governing equations are also applicable to the other symmetric lap joints such as single strap joints and cracked lap shear specimens.
