Structural Steel Design

Tension/compression members, beam-column design, bolted/welded connections, and lateral buckling.

Study the theory, review the governing formula, and test your knowledge with interactive questions.

A beam is a structural member loaded transversely to its longitudinal axis, carrying load primarily by bending and sh...

Buckling is a stability failure in which a slender compression member suddenly develops large lateral (or torsional)...

Columns are **vertical structural members** designed primarily to resist **axial compressive loads**, though they may...

Compression members (such as columns, struts, and truss chords) are structural elements subjected primarily to axial...

Structural connections transfer forces and moments between members while maintaining the intended load path of the st...

Structural steel is an alloy of iron and carbon (typically less than 0.3% carbon) with small amounts of manganese, si...

Tensile members are structural elements designed to resist axial tensile forces. They are commonly found in trusses,...
