What is a shear connection in steel construction?

1. A joint that transfers moment forces

2. A joint allowing the transfer of shear forces

3. A joint for aesthetic purposes only

4. A joint that supports tension loads

The correct answer is: A joint allowing the transfer of shear forces

A shear connection in steel construction is specifically designed to allow the transfer of shear forces between structural components, such as beams and columns. This type of connection enables the structural system to maintain stability by efficiently handling the lateral loads that can occur due to wind, seismic activity, or other forces that seek to displace elements vertically. In this context, shear connections typically involve using simple connections, like bolted or welded connections, that do not resist bending moments. They primarily focus on providing stability by transferring vertical or lateral loads without significant rotation or deflection in the connection itself. This distinguishes them from moment connections, which are designed to resist bending and allow for the transfer of moment forces between connected elements. The other options point to different types of connections or functions. For instance, connections that transfer moment forces are designed to provide rigidity and stability against rotation, while those for aesthetic purposes do not play a structural role in load transfer. Similarly, connections that support tension loads are specifically meant to handle pulling forces, not shear.
