Experimental Studies on Circular CFST Frames with ALC Walls under Cyclic Loadings

다국어 초록 (Multilingual Abstract)

To investigate the interaction and failure mechanism between aerated lightweight concrete (ALC) walls and concrete-filledsteel tubular (CFST) frames under seismic action, one specimen of circular CFST frame and four specimens of circular CFSTframes with ALC walls under cyclic loading were carried out. The test parameters included the panel thickness, the wallconnector type and the panel type. Test process and failure modes of the typed structures were investigated in detail. Hystereticcurves, ductility and energy dissipation etc were also analyzed. The test result showed that using reasonable measurement ofU-typed connector, hooked bolt, rocking connector and angle steel, circular CFST frames and ALC walls under seismicloadings can be in cooperative work and have good seismic performance.
