Abstract:

A brief discussion of various formulations for analyzing creep effects in structures is presented, and detailed attention is directed toward problems involving creep induced instability. The theory of Robotnov and Shesterikov is discussed and it is noted that the application of their theory should be restricted to time intervals during which the change in average strain is small. An alternative formulation which is not subject to this restriction is proposed, and it is applied to the problem of a compressively loaded column and to the problem of a compressively loaded plate. An application of the proposed analysis to available column creep results is made and a good correlation with data is obtained. Author
