Exam 32: Exterior Wall Cladding-Iv Wall System in Glass

In a high- rise glass- aluminum curtain wall, the wind pressures increase with height. With increasing wind pressure, the size of mullions must increase with height. However, aesthetic and detailing considerations require the same size of mullions over the entire building's height. How is this requirement generally met?

In a cable- net- supported glass wall, the glass

A unitized glass curtain wall consists of

In a twin- span mullion system for a glass curtain wall,

Explain the purpose of the following items and state where they are used: (a)shear block, (b)pressure plate, and (c)adapter for spandrel glass.

A stick- built glass curtain wall consists of

In a stick- built glass curtain wall, the mullions are erected first and the rails are inserted between them.

In a stick- built glass curtain wall system, the mullions may span floor to floor (called single- span mullion system)or between two floors (called twin- span mullion system). In the single- span mullion system, each mullion must be anchored to the building's structural frame with two supports, one at each end. What are these supports (anchors)called? Which of these two anchors (supports)is designed to: (i)carry the gravity load of the curtain wall, (ii)accommodate movement in the curtain wall, and (iii)resist the lateral (wind and seismic)load on the curtain wall?

In a glass wall supported by cable trusses, the glass
