Question 1

What does the 'slump test' measure for freshly mixed concrete?

Accepted Answer

Workability (consistency)

Answer

The slump test measures the consistency and workability of fresh concrete by recording how much a cone of concrete settles.

Question 2

Which load combination typically governs the design of a building foundation according to ASCE 7?

Accepted Answer

1.2D + 1.6L

Answer

The combination 1.2D + 1.6L (dead load + live load) is typically the controlling factored load for foundation design under gravity conditions.

Question 3

What is the function of a moment frame in a structural building system?

Accepted Answer

Resist lateral loads through rigid beam-column connections

Answer

A moment frame resists lateral loads through the rigidity of beam-to-column connections, allowing the frame to develop bending moments.

Question 4

In soil mechanics, what is the 'angle of internal friction' (φ) a measure of?

Accepted Answer

Shear strength from particle interlocking

Answer

The angle of internal friction represents the shear strength contribution from inter-particle friction and interlocking in granular soils.

Question 5

Which type of pile transfers load primarily through friction along its shaft rather than end bearing?

Accepted Answer

Friction (floating) pile

Answer

Friction piles transfer structural loads to the soil through skin friction along the pile shaft when competent bearing strata are too deep.
