Behavior of Reinforced Concrete Short Columns with Fiber Reinforced Polymer Bars

This paper presents the results of an experimental investigation of the axial behavior of small scale  square  reinforced  concrete  columns  with  fiber  reinforced  polymer  (FRP)  bars,  as  a solution to overcome the corrosion problems, where this material represents a relatively new technology;  therefore  much  research  is  needed  to  determine  its  characteristics  and  gain confidence  to be accepted by engineers  for practical  application. A series of 8­column was tested  in  a  vertical  position  and  under  compressive  axial  static  loading. Where all  columns had  the  same  dimensions  250*250mm  and  1250mm  height,  main  reinforcement  4#12mm, 6#12mm, and 8#12mm, the transverse reinforcement was ø6@120mm closed stirrups along column. The major parameters  included in this research were  the main reinforcement ratios, the  main  reinforcement  types,  the  transverse  reinforcement  ratios  in  the  column,  and  the characteristic  strength  of  concrete.  Results  from  a  series  of  tests  on  small­scale  specimens showed  that  increasing  main  reinforcement,  transverse  reinforcement  ratios  in  the  column ends  and  increasing  characteristic  strength  of  concrete  have  a  significant  effect  on  the behavior of reinforced concrete columns with GFRP.
