Question 1: When designing a reinforced concrete beam, which factor primarily affects the shear strength of the beam?

Which action should you take?

Choose only one option

Reinforcement bar diameter

Beam length

Load distribution

Concrete compressive strength

Question 2: In reinforced concrete design, what is the role of the neutral axis in bending analysis?

Which action should you take?

Choose only one option

It is the location of maximum compressive stress in the beam

It defines the elastic limit of the concrete section

It is the point where steel reinforcement starts to yield

It is the axis around which the beam experiences no stress

Question 3: In the design of prestressed concrete beams, what is the primary function of the prestressing force?

Which action should you take?

Choose only one option

To resist shear forces

To prevent buckling of the beam

To resist the bending moment

To reduce cracking and control deflection

Question 4: The 2015 International Residential Code (IRC) specifies requirements for what type of structure in residential buildings?

Which action should you take?

Choose only one option

The aesthetic appearance of the roof trusses

The total number of windows and doors in the structure

Load-bearing walls and structural framing components

The minimum insulation standards for attics and basements

Question 5: What does IBC require in terms of safety when designing guardrails for a building under construction?

Which action should you take?

Guardrails must withstand 200 pounds of force per linear foot

Guardrails must be at least 36 inches high

Guardrails must be at least 42 inches high

Question 6: For designing tension members in steel structures, which failure criterion is used to assess the adequacy of the design?

Which action should you take?

Choose only one option
