Name two types of structural steel connections.

The choice of bolted connections and welded connections reflects two fundamental methods of connecting structural steel elements in construction. Both methods are widely used in the industry due to their strength, efficiency, and suitability for various construction applications.

Bolted connections involve the use of bolts to fasten steel members together. This method allows for easier assembly and disassembly, making it particularly advantageous for structures that may need to be modified or dismantled in the future. It also provides significant tensile strength, enabling structures to support heavy loads.

Welded connections, on the other hand, involve melting the edges of the steel members to fuse them together. This creates a continuous connection that can offer a seamless and robust bond, which enhances the overall stability and load-bearing capacity of the structure. Welded connections are often preferred in scenarios where high rigidity is required, and they can be utilized in both structural and ornamental applications.

Together, these two types of connections form the backbone of structural steel construction, highlighting their importance in designing and building safe and effective structures. The other options include connections that may not be standard in structural steel work or do not possess the same level of applicability in current construction practices.
