STRENGTH CHARACTERISTICS OF REINFORCED CONCRETE COLUMNS UNDER SUSTAINED LOADING

This study is concerned with the influence of a sustained load on a column's load carrying capacity. Attention was was restricted to unrestrained, eccentrically loaded columns. Most emphasis was placed on the column strength characteristics at low and intermediate load levels. The limiting case of loads causing creep instability at the end of the time periods considered was also obtained. It was found that the land carrying capacity may be significantly reduced under sustained overlands, and also under sustained service loads for slender columns with small end eccentricities.
