- Abstract:
-
Through the experiments of eight FRP-eonerete-steel tube eomposite square columns subjeeted toeyelie axial compression, the effeets of the loading scheme, the void ratio and the diameter-to-thiekness raticof the inner steel tube on the axial compression behavior were investigated. The test results show that the elffeetof loading seheme on the axial stress-strain envelope and peak load is insignifieant, and ultimate state of FRPconerete-steel tube composile square columns subjected to eyelie axial compression is very similar to that olcomposite square columns subjeeted to monolonous axial eompression. Compared with the void ratio , the diam.eter-to-thickness ratio of the inner steel tube has apparent inlluenee on the peak load of FRP-conerete-steeltube composite square columns subjected to cyelie axial compression.
