Abstract
To investigate the seismic behaviour of reinforced concrete columns mixed with steel fibre and aeolian sand, seven different specimens were built and tested under a lateral cyclic loading test. The specimens included one ordinary reinforced concrete column (RC), three reinforced concrete columns mixed with aeolian sand (ARC), and three reinforced concrete columns mixed with steel fibres and aeolian sand (SARC). The seismic behaviour of specimens was studied by comparing the seismic indexes exhibited in the test. The results show that SARC specimens with 30% of aeolian sand replaced in the mix has better seismic behaviour than that of the other specimens. The influence of steel fibres on the seismic behaviour of the SARC specimens is strengthened by increasing the replacement rate of aeolian sand.
