5.1.3.5 Strap Joint
Strap joints are very common in practical applications, such as repairs, and are generally used when overlap joints are impractical due to substrate thickness. They are also used as a reinforcement method to increase the bonding area and reduce peel stresses. The use of thick belts, also known as straps, with tapered or bevelled ends, can further reduce peeling stresses.
5.1.3.6 Single Strap Joint
A single strap joint is a type of butt joint in which only one cover plate is bonded on the main plate. This configuration allows for the increase of the contact surface for the butt joint and limits the peel forces exerted on the joint with respect to the ‘strapped’ side of the substrates.
This type of joint is subject to resisting bending and shear forces. The main weakness of this joint is the stresses of 90 degrees perpendicular to the substrate applied to the ‘strapped’ side of the joint.
