Advanced Steel Structures - Quiz II

Which frame is subjected to lateral sway due to external forces?

• Sway frame

• Non-sway frame

• Pin-jointed frame

• Hinged frame

A non-sway frame primarily resists loads through:

• Flexural strength

• Axial strength

• Shear strength

• Torsional strength

Which of the following is a functional requirement of a structural connection?

• Cost efficiency

• Transfer of load

• Aesthetic appearance

• Minimizing the number of bolts

Gantry girders are primarily used in:

• Bridges

• Industrial buildings with cranes

• Multi-storey buildings

• Residential buildings

The shape factor of a section is defined as the ratio of:

• Plastic moment to elastic moment

• Elastic moment to plastic moment

• Shear force to axial force

• Axial force to moment

The moment redistribution in beams is used to:

• Increase deflection

• Optimize material usage

• Reduce shear forces

• Increase axial forces

In a portal frame, the effect of axial force on plastic moment capacity is:

• Negligible

• Significant

• Dependent on the beam span

• Irrelevant

In a portal frame, the combined mechanism is a result of:

• Bending moment only

• Axial force only

• Combination of beam, sway, and joint mechanisms

• Torsion and bending

Plastic hinges form in a structure when:

• Elastic limit is reached

• Yield moment is exceeded

• Maximum shear force is reached

• The structure is under torsion

Which mechanism is formed by plastic hinges at the supports and the center of a beam?

• Sway mechanism

• Beam mechanism

• Joint mechanism

• Gable mechanism
