【 摘 要 】

Aeoliansandisakindofnaturalmaterialwithabundantreservesandalowprice.Many scholarshaveconductedextensivestudiesontheengineeringapplicationsofaeoliansand.This paper addresses the seismic damage behaviour of aeolian sand concrete columns to promote the applicationofaeoliansandinframestructures.Atotalof5aeoliansandconcretecolumn specimens with different reinforcements were studied using cyclic loading tests. The failure modes, stiffness degradation, bearing capacity, hysteresis peculiarity, ductility, and energy consumption of the specimens were analysed and compared. Then, applicable damage models of the specimens wereproposed.Thestudyresultsprovethattheseismicdamagebehaviourofthespecimens increases with the increase of longitudinal reinforcement percentage and with the transverse steel ratiowhenthereplacementpercentageofaeoliansandisconstant.Additionally,thedamage model which is revised in this paper agreeswell with the test results. It can be used to assess the degree of damage to the aeolian sand concrete columns.
