Question 1

A simply supported beam of span 8 m carries a uniformly distributed load of 10 kN/m. What is the maximum bending moment?

Accepted Answer

80 kN·m

Answer

Maximum bending moment for a simply supported beam with UDL = wL²/8 = 10×8²/8 = 80 kN·m.

Question 2

Which of the following best describes the condition of a 'statically determinate' structure?

Accepted Answer

Reactions and internal forces can be found using equilibrium equations alone

Answer

A statically determinate structure has exactly as many unknowns as equilibrium equations, so all reactions and internal forces can be solved without material properties.

Question 3

In reinforced concrete design, the term 'balanced section' refers to:

Accepted Answer

A section where concrete crushing and steel yielding occur simultaneously

Answer

A balanced section is one in which the extreme concrete fiber reaches its crushing strain (0.003) at the same time the tension steel reaches its yield strain.

Question 4

What is the slenderness ratio of a column, and which value typically indicates a 'long' (slender) column?

Accepted Answer

KL/r; values greater than 120 are typically considered long columns

Answer

Slenderness ratio = KL/r, where K is the effective length factor, L is column length, and r is radius of gyration; values above about 120 generally classify a column as slender.

Question 5

According to limit state design philosophy, the ultimate limit state (ULS) is primarily concerned with:

Accepted Answer

Structural collapse or failure of the structure

Answer

The ultimate limit state addresses structural safety against collapse, including yielding, buckling, fracture, and overturning.
