Abstract

Abstract

In order to reveal the failure mechanism and bearing capacity of extended service reinforced concrete pole strengthened with carbon fiber reinforced polymer (CFRP),4 reinforced concrete poles were designed for bending test,including three reinforced concrete poles strengthened by CFRP and one common reinforced concrete pole. According to the test,the whole failure process,failure pattern,the complete loading-displacement curve and the ultimate bearing capacity were obtained. Experimental results showed that the failure progress of CFRP strengthening reinforced concrete pole was very rapid and no premonition,CFRP fracture was the final failure pattern of specimens. The concrete pole bearing capacity was improved apparently by CFRP strengthening technology. With the layer of CFRP increasing,the bearing capacity was improved,but the improvement was not linear.
