Term
Foundations utilize which of the following to transmit loads to the earth:
Definition
bearing walls, columns & piers
Term
Foundations are designed considering:
Definition
subsurface conditions, site topography, building code requirements
Term
The most common types of spread footings are:
Definition
strip footings & isolated or pad footings
Term
Foundation walls:
Definition
support a building superstructure, anchor the supstructure against wind & seismic forces, resist earth pressure
Term
Foundation walls can be anchored to footings by:
Definition
shaped mechinical keyways & steel dowels
Term
the size of a footing depensd on:
Definition
the allowable bearing capacity of the soil & the foundation wall load
Term
Foundation walls can be constructed from:
Definition
treated wood, concrete block masonry & reinforced concrete
Term
T/F? A foundation wall sill plate typically is made of treated wood to prevent moisture damage from moisture wicking up a foundation wall. 
Definition
true.
Term
T/F? Damp-proofing of a foundation wall is used where hydrostatic pressure is likely.
Definition
False
Term
Water along a foundation wall can be  accommodated by:
Definition
a footing drain & a drainage mat or gravel backfill
Term
A concrete slab might have which type of joint?
Definition
construction joint, control joint, & isolation joint
Term
Control joints can be formed in a concrete slab by:
Definition
inserting a pre-molded strip in the top of a slab, creating a keyed joint between sections of a slab & sawing a slot in the top of the slab
Term
Loads transmitted onto slabs on grade require:
Definition
an intergral footing OR an independent footing
Term
T/F? Where frost is not an issue, a slab on grade could use a thickened-edge to support exterior walls.
Definition
true.
Term
Welded wire fabric reinforcement, also know as welded wire mesh (WWM) is used to:
Definition
accomdate slight differential movement in the soil, control thermal stresses in a slab, control shrinkage cracking
Term
Piling foundations rely on:
Definition
friction of the adjacent soil OR deep bearing stratum or bedrock
Term
How is a basement foundation wall typically laterally supported at the base?
Definition
Poured floor
Term
How is a basement foundation wall typically laterally supported at the top?
Definition
Floor deck
Term
The depth of a floor system is related to:
Definition
The size and proportions of the structural bays supporting it & the strength of the materials used in it
Term
T/F? Wood sheathing for a floor deck requires relatively closely-spaced wood joists for support.
Definition
True
Term
Steel reinforcing bars in concrete are required to resist:
Definition
tension forces
Term
A two-way concrete slab transfers loads to:
Definition
Four supporting edges, in both directions.
Term
The slight bending or curvature formed in pre-stressed concrete is called:
Definition
Camber
Term
T/F? Poured-in-place concrete construction does not require temporary formwork and shoring support.
Definition
False
Term
T/F? Pre-cast concrete planks typically have a thin concrete topping, applied after installation.
Definition
True
Term
The horizontal members of a steel beam are called:
Definition
Flanges
Term
The vertical member of a steel beam is called a:
Definition
Web.
Term
The horizontal members of a wood or steel floor truss are called:
Definition
Chords.
Term
Open web steel joists are typically supported by their:
Definition
Top Chord.
Term
Metal decking is corrugated to:
Definition
increase span & inscrease stiffness
Term
Light-gauge steel floor framing is most similar to:
Definition
wood joinst framing
Term
Wood joists are typically spaced:
Definition
12", 16", 24" on center
Term
What is a disadvantage of high deflection in a floor system?
Definition
unsuitable for brittle finishes
Term
What is a way a floor joist could be supported with its top flush with a supporting beam?
Definition

a header

Term
What is a function of bridging in a wood joist floor system?
Definition
transfer loading to other joists for composite action.
Term
Which is a more appropriate floor system for concealed mechanical systems?
Definition
open-web steel joists
Term
What is Baloon framing?
Definition
Floor components hung on side of or let into wall components.
Term
What is a disadvantage of a wood beam/wood decking floor system?
Definition
exposed mechanics
Term
Which of the following is open-web steel joist floor framing most similar to?
Definition
one-way slab floor systems
Term
Which floor deflection ratio is the least stiff, where D is the amount of vertical deflection and L is the length of the span?
Definition
D = L / 240
