Bolted and welded joints transfer forces between members.
Bolted (bearing, slip-critical, pretensioned) and welded connections transfer forces between members; types: simple (shear), moment, and bracing connections. Failure modes: bolt shear, bearing, block shear, weld failure, prying. Detailing drives fabrication cost and robustness.
End-plate moment connections create rigid portal frames.
Connections transfer forces between members and often control the strength of the whole structure, so they need careful design.

Connections transfer forces between members and often control the strength of the whole structure, so they need careful design.
Bolted connections, welded connections and sometimes pinned or moment connections, depending on the force transfer required.
Many failures happen at connections because stress concentrates there and fabrication errors are more likely.
Typical applications include designing a bolted joint between a beam and a column, welding a bracket to a steel column and checking a moment connection in a steel frame.
Study "Steel beam and column design" first (topic 57 of 112 in Civil & Structural). It covers the groundwork this topic builds on.
Bolt groups. Fillet weld capacity. Base plates.
End-plate moment connections create rigid portal frames.
The next topic is "Composite structures", which builds directly on this one.
It is classed as Intermediate in Civil & Structural (topic 58 of 112). It is an intermediate topic. Work through the beginner topics in Civil & Structural first.
