A heavy timber building is primarily fire protected by ✔Correct Answer-specifying minimum
wood cross sections
Beams used in Heavy Timber construction are sometimes firecut. This is done to: ✔Correct
Answer-Allow the beam to rotate out of the wall if it burns through
Which of these decking types is not permissible in type IV-HT construction? ✔Correct Answer-
Box beams (joists with planking on top and bottom)
Wood-concrete systems are efficient structural solutions because ✔Correct Answer-a shear
connector between the concrete and the wood allows both materials to act as a composite.
Which of the following is not associated with achieving longer spans in heavy timber frame
construction? ✔Correct Answer-the use of pintels

building
The highest hydraulic pressure on vertical formwork occurs: ✔Correct Answer-At the bottom
of a wall
Which of these is not true for columns? ✔Correct Answer-Stirrups are added for shear
reinforcement.
Overtime concrete deforms because of: ✔Correct Answer-A. dry shrinkage
B. Loads placed on it
C. creep deformation
, D. A and B only
E. All of the above Answer is E.
The amount of portland cement in concrete can be reduced by: ✔Correct Answer-Any of the
above
Fly ash, accelerators, superplasticizers, and air entrainment are added to a concrete mix to
✔Correct Answer-to alter its properties in different ways
Admixtures are used in concrete to: ✔Correct Answer-delay hardening
Which of these can provide two-way structural action? ✔Correct Answer-cross laminated
timber and concrete slab

strength the fastest? ✔Correct Answer-Type III
Which of the following is most closely associated with reinforcing steel? ✔Correct Answer-
Welded wire fabric
Concrete must be compacted in the forms to eliminate trapped air and to fill completely around
the reinforcing steel and into all the corners of the formwork. What tool is used to accomplish
this? ✔Correct Answer-Vibrator

Answer-cost of the concrete to the customer
Segregation was likely occur during concrete placement if the concrete is: ✔Correct Answer-
dropped from a substantial height
Chairs and bolsters are used to ✔Correct Answer-support reinforcing bars in beams and slabs,
prior to concrete placement.
Posttensioning a concrete element (e.g., a beam, girder, or slab) helps the concrete element to:
✔Correct Answer-achieve a longer span than would otherize be possible
Reinforcing steel and concrete are very compatible. Which of the following is untrue?
✔Correct Answer-Individually, each has a very high allowable tensile strength
