NUMERICAL ANALYSIS OF EFFECTIVENESS OF STRENGTHENING CONCRETE SLAB IN TENSION OF THE STEEL-CONCRETE COMPOSITE BEAM USING PRETENSIONED CFRP STRIPS
Journal Title: Civil and Environmental Engineering Reports - Year 2017, Vol 4, Issue 27
Abstract
One of the methods to increase the load carrying capacity of the reinforced concrete (RC) structure is its strengthening by using carbon fiber (CFRP) strips. There are two methods of strengthening using CFRP strips - passive method and active method. In the passive method a strip is applied to the concrete surface without initial strains, unlike in the active method a strip is initially pretensioned before its application. In the case of a steel-concrete composite beam, strips may be used to strengthen the concrete slab located in the tension zone (in the parts of beams with negative bending moments). The finite element model has been developed and validated by experimental tests to evaluate the strengthening efficiency of the composite girder with pretensioned CFRP strips applied to concrete slab in its tension zone.
