Exam 26: Masonry and Concrete Bearing Wall Construction

The clear height of openings in CMU walls is

Why do multistory, load- bearing wall buildings have a cellular type structure?

What is the role of vertical reinforcement in masonry walls?

The most commonly used method of connecting tilt- up walls to the slab- on- ground is

What are the bond beams in masonry walls constructed of?

To provide continuous insulation in a tilt- up wall building, the choice generally is the use of

With the help of a sketch, explain what the tunnel form is, and describe its benefits and limitations.

With the help of sketches and notes, explain why the walls in a traditional masonry- bearing wall structure had to be extremely thick.

A load- bearing wall structure works best when the floor plan of the building has

The thickness of tilt- up wall panels is obviously related to the magnitude of stresses caused in them due to the loads on the panels. Two types of stresses are caused in panels: (i)the stresses caused by gravity loads and lateral loads after the building has been constructed, i.e., in- service loads and (ii)stresses caused during the lifting and erection of panels. Which of these two stresses determines the panel thickness and why?

Bond beams in load- bearing masonry walls are constructed of either masonry bond beam units or as reinforced concrete beams. What is (are)the advantage(s)of using reinforced concrete bond beams?

In a tilt- up wall building with a large footprint, the exterior walls are constructed of concrete tilt- up wall panels. What does the interior structure of the building consist of?

Bond beams in load- bearing masonry walls are constructed of either masonry bond beam units or as reinforced concrete beams. Why is the use of masonry bond beam units preferred for their construction?

The tilt- up wall construction uses load- bearing reinforced concrete walls. Are the tilt- up walls used only for the building exterior or are they used for both interior and exterior walls of the building?

How long after placing concrete in them are the tunnel forms typically removed?

In high- rise residential buildings built with site- cast reinforced- concrete bearing walls using tunnel forms, the floors and roofs are generally constructed of

What are form liners, as used for casting of tilt- up wall panels?

With the help of sketches and notes, explain the details of: a. Double- sealed tilt- up wall panels b. Tilt- up wall sandwich panels

A bond beam in a masonry bearing wall building must be

Reinforced- concrete tilt- up walls are generally used as
