Experimental Investigation of the RC Columns Strengthened with Outer Closed SCC under Cyclic Loadings

Abstract:

Experiment research for aseismic performance of RC Column strengthened by self-compacting concrete under second force is completed. By comparing three comparison columns and three columns strengthened by self-compacting concrete in low-cycle reciprocating horizontal loads seismic performance test, the specimen described the typical features of breakage, and the hysteresis and ductility of the RC column reinforced or not by self-compacting concrete is analyzed, the reinforcement effect by the different initial force is compared. The results show that: reinforcement by increasing the cross-section of self-compacting concrete is an effective method to significantly improve the shear strength of reinforced concrete columns and specimen ductility. The presence of the initial force have impact on reinforcing effect of RC columns, the greater the initial force, the more obvious impact.
