Which type of steel beam connection consists of beams linked to supporting elements with a web connection angle?

Answer: A — Bolted framed connections

The correct answer is that bolted framed connections consist of beams linked to supporting elements using a web connection angle. In bolted framed connections, the beams are connected to vertical or horizontal members typically at their web, allowing for the efficient transfer of loads between the structural elements. This type of connection is favored for its structural integrity and ease of assembly. These connections often use angles or plates that are bolted to both the supporting element and the beam web, ensuring that forces are properly transmitted through the connection without requiring extensive field welding, which can lead to delays and increased labor costs. In contrast, the other options involve different types of connections. Bolted seated connections and welded seat connections generally refer to connections where the beam sits on or is seated against a support, which may involve the use of plates or other components that are not primarily reliant on web attachment. Welded framed connections provide an alternative method of connecting elements but do not typically involve the use of web angles in the same prominent manner as bolted framed connections do.
