Terminology in steel structures: A structural member that carries tensile force along its longitudinal axis is commonly called what?

Introduction / Context:
Steel frameworks contain elements that are primarily in tension or compression. Correct terminology helps in communication, specification, and code application. Members designed to resist axial tension are used in trusses, bracing systems, and hangers.

Given Data / Assumptions:

• The member carries axial tensile force parallel to its length.
• No significant bending is intended in the basic definition.
• Standard structural engineering terminology is used.

Concept / Approach:

Common interchangeable terms include tie, tie member, and tension member. In truss nomenclature, “tie” denotes a member resisting tension. Design checks for such members focus on gross and net section strength, slenderness for serviceability, and connection detailing to avoid net-section fracture or block shear.

Step-by-Step Solution:

Verification / Alternative check:

Textbooks and codes use these terms almost synonymously in the context of trusses and bracing. Drawings often label long tensile elements as “ties”.

Why Other Options Are Wrong:

• “None of these” is wrong because all listed terms are valid.

Common Pitfalls:

• Ignoring net-area reductions at bolt/rivet holes when sizing tension members.
• Overlooking minimum thickness and slenderness limits even for members in tension.

Final Answer:

all the above.
