The element enabling the connection of the two dissimilar materials (steel and concrete/masonry) are fasteners, which resist the tension component of the applied force. The fasteners transfer the applied tension and shear loads to the base material (concrete/masonry) through various mechanisms shown in the attached image. For an efficient and reliable design, we must understand the behaviour of each element forming a post-installed connection.
Mechanical fasteners work via interlock (keying) and friction while chemical fasteners work via adhesive bonding between the fastener and base material. We will discuss more on working principles of post-installed fastening and their failure modes in subsequent blogs.
At KA Engineering Group, we leverage on our extensive experience to design and recommend most efficient fastening solutions for new as well as existing systems in telecom construction.
