Abstract:
The results of a study of the sustained load effects on the interior reinforced concrete columns in rectangular building frames are presented. The two major variables considered are the column slenderness ratio and the level of sustained loads. The behavior under sustained loads is predicted by using a time-dependent stress-strain diagram for concrete. It is found that the column capacity decreases as the slenderness ratio and level of sustained load increase.
