Exam 28: Exterior Wall Cladding-II Masonry, Precast Concrete, and Gfrc

What is the typical thickness of CMU wall used as a backup for brick veneer in a reinforced concrete frame structure? Is this wall designed as a load- bearing or a non- load- bearing wall?

The connection between the natural stone facing and the backup concrete in a stone- faced precast concrete curtain wall panel is obtained by

In a brick veneer wall assembly, the wind loads are transferred directly from the veneer to the building's structure.

The dead load support for brick veneer in a multistory building is typically provided through galvanized steel shelf angles at every elevated floor. The code permits the first 30 ft height of the veneer to be supported on wall foundation. Can the first one or two shelf angles below 30 ft height be eliminated? Explain.

The structural design of precast concrete curtain wall panels is generally the responsibility of the

Discuss the pros and cons of using a CMU backup wall versus a steel stud backup wall in a brick veneer wall assembly.

What is flashing and where is it used in a brick veneer wall assembly?

GFRC curtain wall panels are generally lighter than the corresponding precast concrete curtain wall panels.

The minimum required width of the air space between a brick veneer and a CMU backup wall is

A GFRC curtain wall panel consists of

The anchors in a brick veneer wall assembly transfer the lateral load on the veneer to the backup. What is the dead load of the veneer supported on for a building whose height is 25 ft?

Are precast concrete curtain (PCC)wall panels with thin brick facing made by adhering the bricks with mortar on an already fabricated PCC panel? Explain.

The GFRC skin is typically

What does a glass fiber- reinforced concrete (GFRC)curtain wall panel consist of?

With the help of sketches and notes, explain the support system of a precast concrete curtain wall panel.

The glass fiber- reinforced concrete (GFRC)skin is connected with cold- formed steel (CFS)backup frame with anchors. Why are these anchors called flex anchors?

What does the term "GFRC" in GFRC curtain wall panel stand for?

A brick veneer wall assembly must have a backup wall and so must a precast concrete curtain (PCC)wall. What is the difference between the two backup walls?

The strength of concrete used in precast concrete curtain walls is generally

In a multistory building, shelf angles are typically used at
