9.11 As shown, a curtain wall is constructed of brick masonry (a bottom of the masonry wall bears on the leg of a steel angle that is welded to and extends from a steel spandrel beam at each floor. The wall extends to the bottom side of the leg of a steel angle on the upper floor. The wall measures 12.0 ft and is fully restrained be- tween the angles. It is installed at a temperature of 55°F. On a hot summer day, the tem- perature of the wall can rise to 90°F. In the winter, the temperature of the wall can fall to 20°F. Stress due to weight of the wall is 15 lb/in² at the base of the wall (at the bearing point on the angle). (a) Determine the maximum thermal stress that develops in the curtain wall. (b) Determine the maximum stress that develops in the curtain wall with this tempera-

Temperature Difference and Heat Transfer

Whenever there is a flow of heat flux resulting from a temperature gradient within the material or between two materials, there is heat transfer. Heat transfer primarily arises due to temperature differences between two bodies or within bodies. The term temperature gradient denotes temperature differences or variation of temperature due to change in some quantity. The fundamental use of the concept of temperature is found in the zeroth law of thermodynamics.
