摘要：The concentrically compressive behaviour of Recycled Aggregate Concrete (RAC) Filled Stainless Steel Tube (RACFSST) stub columns was experimentally studied, and a total of 14 composite specimens were tested. The experiments were carried out on circular and square specimens with recycled aggregate replacement ratio of 0, 25%, 50% and 75%, and both recycled coarse aggregates and recycled fine aggregates were used in the tests. The main objectives of the tests were threefold: first, to describe a series of tests on RACFSST stub columns; second, to evaluate the effects of cross-section type and recycled aggregate replacement ratio on the behaviour of RACFSST stub columns; and finally, to predict the load versus deformation relation of RACFSST stub columns by a Finite Element Analysis (FEA) model. The test results indicated that the RACFSST stub columns subjected to concentric compression had the stable load versus deformation response, and the compressive behaviour of RACFSST stub columns were significantly affected by the recycled aggregate replacement ratio. Moreover, the predicted load versus deformation relation of RACFSST stub columns was generally agreed well with the tested results.
