Continuous lengths of purlin result in better economy, but lapping provides two thicknesses of metal over interior supports. Lapping increases the strength of the sections where bending moments and shear are at a maximum, thus improving the load capacity and rigidity of the system.

A series of nine cold-formed steel Z sections with sleeved and overlapped bolted connections were tested in bending. These types of cross-section and connections are largely used in continuous multi-span cold-formed steel purlin systems. This paper aims to analyze the strength and stiffness of semi-continuous purlins subjected to flexure.
