- Abstract:
- Based on axially compressive tests of conerete filled steel tubes short columns with waste conereteblock , the inlluenee of ineorporation rate of lower compressive slrength to maeroseopie charaeters of deforma.tion, load - vertical deformation curves and bearing capaeity-ineorporation rate were studied, and applicabilityof three theorelieal ealeulation formulas of conerete filled seel tubes were analyzed. The test results demon.strate that failure mode, duetility and later bearing eapacity of conerete filled steel tubes short columns withwaste conerete block is similar to conerete filled steel tubes, but the bearing eapacity will deerease when ineor.poralion rate of waste conerete block inereases, and the maximum amplitude is 14%. Based on the comparisonbelween the results of three caleulation theories and test results, different caeulation formulas are recommen-ded from different aspects.
