What is the primary purpose of tie rods in a structure?

• To resist tensile forces
• To resist compressive forces
• To provide insulation
• To resist bending moments

Answer explanation

Tie rods are structural members designed to resist tensile forces, such as pulling.

In which type of beam does one end remain fixed while the other end is free?

• Cantilever beam
• Simply supported beam
• Overhanging beam
• Continuous beam

Answer explanation

A cantilever beam has one fixed end and one free end.

What does a buckling failure in a column typically result from?

• Axial compression
• Lateral tension
• Bending stress
• Shear force

Answer explanation

Buckling occurs due to axial compression leading to instability in the column.

What is the reaction at a fixed support?

• Horizontal, vertical, and moment
• Vertical and moment
• Horizontal and vertical
• Moment only

Answer explanation

A fixed support resists forces in horizontal and vertical directions and also provides a moment reaction.

Which structural element is used to resist bending in buildings?

• Beams
• Columns
• Tie rods
• Slabs

Answer explanation

Beams are horizontal members primarily used to resist bending caused by loads.

What differentiates a two-way slab from a one-way slab?

• Longer span divided by shorter span ≤ 2
• Shorter span divided by longer span > 0.5
• Material of the slab
• Support types

Answer explanation

Two-way slabs are classified when the longer span divided by the shorter span is less than or equal to 2.

What structural property does slenderness ratio affect in a column?

• Stability
• Strength
• Elasticity
• Rigidity

Answer explanation

A higher slenderness ratio decreases the stability of a column, leading to potential buckling.

Why is determining reactions at supports essential in structural analysis?

• To compute structural determinacy
• To estimate material costs
• To predict aesthetic design
• To simplify construction

Answer explanation

Reactions are necessary for determining whether a structure is statically determinate or indeterminate.

Which type of beam typically has overhanging ends beyond its supports?

• Overhanging beam
• Simply supported beam
• Cantilever beam
• Continuous beam

Answer explanation

Overhanging beams have supports in between, with extensions beyond their ends.

What forces act on a column?

• Axial compressive forces
• Tensile forces
• Shear forces
• Torsional forces

Answer explanation

Columns are primarily subjected to axial compressive forces.
