Which member is the main member in a single-shear connection?
For tapered tip fasteners, the main member is the one that contains the point of the fastener. For bolted connections, the distinction is less clear. In general, it is assumed the member which applies the load is the side member, but it actually doesn’t matter as long as the correct properties are used for the main and side members respectively.
