NCEES Structural Engineering PE Exam 1

Question 1

According to NCEES PE Structural exam standards, which load combination from ASCE 7 governs strength design for a building subjected to dead, live, and wind loads?

Accepted Answer

1.2D + 1.0W + 1.0L

Answer

ASCE 7 load combination 1.2D + 1.0W + 1.0L (or +0.5S) governs when wind load is a primary variable action alongside dead and live loads.

Question 2

In the NCEES PE Structural exam, what is the purpose of a moment frame in a building's lateral force-resisting system?

Accepted Answer

To resist lateral forces through bending in beams and columns

Answer

A moment frame resists lateral (wind or seismic) forces through flexural rigidity developed by moment connections between beams and columns.

Question 3

For the NCEES PE Structural exam, what does the term 'effective length factor K' represent in column design?

Accepted Answer

A modifier that accounts for end conditions affecting buckling length

Answer

The effective length factor K adjusts the actual column length to an equivalent pin-ended length based on end restraint conditions for Euler buckling calculations.

Question 4

On the NCEES PE Structural exam, which failure mode governs the design of a short, stocky concrete column?

Accepted Answer

Material crushing/yielding

Answer

Short columns fail by material crushing (concrete compression or steel yielding) rather than elastic buckling, which governs slender columns.

Question 5

In NCEES PE Structural exam context, what is the significance of the 'plastic moment' Mp in steel beam design?

Accepted Answer

The maximum moment capacity when the full cross-section yields

Answer

The plastic moment Mp represents the theoretical maximum bending capacity achieved when the entire cross-section has yielded, forming a plastic hinge.
