Experimental Research on Seismic Behavior of Unbonded Precast Reinforced Concrete Frame

Unbonded precast reinforced concrete frame is a new assembly architecture structure. This thesis studies deeply the crack development characteristics, failure pattern, hysteresis curve and the displacement ductility of unbonded precast reinforced concrete frame, by analyzing one unbonded precast reinforced concrete frame under low reversed cyclic load test. We build a model using finite element analysis software to the test piece model analysis, the analysis result consistent with the experimental results. Experimental studies indicate that assembly of prestressed reinforced concrete frame structure has a good seismic performance. This unbonded precast reinforced concrete frame is a new kind of structural system complying with the development of architectural engineering, which is useful in application in the earthquake area.
