As shown, a curtain wall constructed of brick masonry (a = 0.000 009 m/m-°C) bears on a steel angle that extends from a steel spandrel beam at each floor. The brick curtain wall measures 4.0 m vertically between bearing points. The wall will be designed to endure a 45°C temperature change. Dimensional change due to thermal expansion and contraction is limited to 2.0 mm between steel angles.

(a) Determine the maximum change in height of the masonry wall with this temperature change.

(b) Is dimensional change from the 45°C temperature change acceptable?
