Research Of Theory And Test On Hysteretic Behavior Of Concrete-Filled Square Steel Tubular Frame After Consolieated

Through modeling reinforced square steel tube, the context analyzed reinforced frame delaying capability intensity rigid degeneration and shake resist capability under low-circle repeat level load, came out displacement sluggish-circle curve under repeat load, and got frame, tip framework curve and resilience model. Through comparing with the origin, we can get reinforced frame, sluggish-circle curve, delaying index, ability consuming capability, intensity and rigid degenerating and shake resisting capability difference with the origin. Intending to observe reinforced frame, delaying capability and ability consuming capability, and applying this into the engineering .In the last through ANSYS modeling, we got sluggish-circle curve, and compared experimentation curve. The result proved: theory and experimentation modeling can create very perfect effect.
