Abstract

In a slender column under sustained eccentric compression, the deformations caused by creep and shrinkage can lead to an increase in the loads on the structure and a reduction in strength. This study presents a methodlogy and improved computer program for the analysis of time-dependent long column in considering slender effects and nonlinear behaviors. In this result, when slenderness ratio is greater than 80, we know that magnified moment methods may be not applied in long columns.
