Differential Temperaure Moments in Rigid Frames
Appears on pages(s):
Methods of analysis for bending moments in one story rigid frames and arches due to transverse differential temperatures are presented. Use is made of temperature distribution diagrams analogous to moment diagrams to obtain fixed-end moments and deflections for straight members. Formulas are developed giving deflections and angle changes for both straight and curved members fixed at one end and free at the other. Examples are given in which members of both constant and variable depth are used. The moment distribution method is used for analysis of a tunnel section and the column analogy is used for the moment analysis of an arch and a one-story frame.
