Why are structural steels considered tough?

They have high strength and high ductility.

What advantage does steel have that allows it to be bent, hammered, and sheared without visible damage?

Toughness with large elongation

Why do most steels need periodic painting when freely exposed to air and water?

To prevent corrosion

In what common situation does the strength of structural members reduce significantly?

When exposed to high temperatures

How does the danger of buckling in a compression member change with an increase in length and slenderness?

It increases

What allows steel structures to have new bays or entire wings added to them without issues?

Toughness and ability to withstand large deformations

What undesirable property of steel is mentioned in the text?

Reduction in strength due to stress reversals

Which type of structures are listed as examples of where steel is used?

Multi-storey & high-rise buildings

What is emphasized about the structural shapes of steel in the text?

Large moments of inertia in proportion to their areas are desirable

What organization published the Steel Construction Manual?

American Institute of Steel Construction (AISC)

What type of shapes, commonly used in steel structures, are mentioned in the text?

I, T, and C shapes

How are structural shapes identified for use in drawings, specifications, and designs?

By a standardized system described in the AISC Manual

Why is the high strength of steel per unit of weight important in construction?

To minimize the weight of structures, especially for long-span bridges and tall buildings

How does the uniformity of steel properties compare to reinforced-concrete structures?

Steel properties remain consistent over time, unlike reinforced-concrete

Which mechanical property of steel allows it to withstand extensive deformation without failure under high tensile stresses?

Ductility

Why is the characteristic of elasticity in steel advantageous in design?

It allows steel to follow Hooke's law up to high stresses

What is the implication of the property of permanence in steel frames?

Steel frames can last indefinitely with proper maintenance

How does the property of ductility in steel contribute to its structural behavior?

'It allows steel to deform significantly without breaking under high tensile stresses'
