Experimental Investigation of Circular Reinforced Concrete Columns Exposed to Elevated Temperatures

Research output: Chapter in Book/Entry/PoemConference contribution

Abstract

This paper presents an experimental study on thermal and structural performance of fire-damaged circular reinforced concrete (RC) columns with medium and high strength concretes. A total twelve circular RC columns were exposed to elevated temperatures following the ISO 834 standard fire curves up to 120 min. The investigation focused on the effect of concrete compressive strength and fire duration on the residual axial capacity. The paper presents the temperature radiation into the column’s section versus duration and exterior temperature levels. In addition, detailed deterioration damage of the columns, residual axial load carrying capacity and load-displacement response of columns are presented. Detailed review of experimental work done by others is also presented.
