What does the 'slump test' measure for freshly mixed concrete?
Answer: Workability (consistency)
The slump test measures the consistency and workability of fresh concrete by recording how much a cone of concrete settles.
Which load combination typically governs the design of a building foundation according to ASCE 7?
Answer: 1.2D + 1.6L
The combination 1.2D + 1.6L (dead load + live load) is typically the controlling factored load for foundation design under gravity conditions.
What is the function of a moment frame in a structural building system?
Answer: Resist lateral loads through rigid beam-column connections
A moment frame resists lateral loads through the rigidity of beam-to-column connections, allowing the frame to develop bending moments.
In soil mechanics, what is the 'angle of internal friction' (φ) a measure of?
Answer: Shear strength from particle interlocking
The angle of internal friction represents the shear strength contribution from inter-particle friction and interlocking in granular soils.
Which type of pile transfers load primarily through friction along its shaft rather than end bearing?
Answer: Friction (floating) pile
Friction piles transfer structural loads to the soil through skin friction along the pile shaft when competent bearing strata are too deep.
What is 'elastic shortening' in prestressed concrete construction?
Answer: Immediate shortening of concrete when prestress force is applied
Elastic shortening occurs immediately when the prestressing force is transferred to the concrete, causing an instantaneous compressive strain.
According to IBC, what minimum live load is typically required for office floors?
Answer: 50 psf
The IBC requires a minimum uniform live load of 50 psf for office occupancies.
