EXPERIMENTAL RESEARCH ON BEARING CAPACITY OF STEEL REINFORCED RECYCLED AGGREGATE CONCRETE COLUMNS

摘要：

　　In order to reveal the mechanical performance of steel reinforced recycled concrete columns,9 specimens were designed for eccentric compression experiment.And two running parameters which are recycled aggregate replacement ratio and relative eccentricity are taken into consideration.Base on the test,the stress distribution,ultimate bearing capacity,load-strain curve and other important data are obtained.Tests showed that the destructive process and failure mode of steel reinforced concrete column similar to ordinary steel reinforced concrete columns.It is showed that the failure mode include large eccentric compression failure and micro eccentric compression failure,with the increase of eccentricity relative,the ultimate bearing capacity of composite columns is decreasing,while the replacement rate of recycled aggregate changes to the bearing capacity is not obvious.
