Experiment And Research On Seismic Capability Of Spcial-Shaped Column Frame After Reinforced

This thesis introduces detailed the experiment on antiseismic behavior of special-shaped column frame strengthened by wrapping steels and gluing steels suffered low frequency cyclic load about the experiment design,the expreriment process and result, intending to observe reinforced frame,ductile capability and ability consuming capability, and applying this into the engineering. Through model reinforced of special-shaped column frame, the context analyzed reinforced frame,ductile capability,intensity,rigid degeneration and shake resist capability under low frequency cyclic load, came out hysteresis curve under repeat load, and got frame,tip framework curve and resilience model. Comparing with the origin, we can get difference reinforced frame between the origin. Through analyzing the failure forms,hysteresis curves,intensity and rigid degeneration,ability consuming capability and the strain of bars,steels and angle steels in special-shaped column frame model, we draws the conclusion of wrapping steels and bonding steels have improved the carrying capacity. Contrasting model strengthened and origin, the former have good ductility and energy consumption capacity, achieving the requirement of"strong column weak beam","strong joint weak components".
