If it is decided to provide an opening in the beam at post-construction stage, the opening zone needs to be strengthened for avoiding premature beam failure. Fiber reinforced polymer (FRP) has been found to be effective for external strengthening in such cases due to a number of advantages, such as excellent strength to self-weight ratio, high tensile strength, large fatigue ...

THIS PAPER PRESENTS A NONLINEAR FINITE ELEMENT ANALYSIS (FEA) THAT HAS BEEN CARRIED OUT TO STUDY THE BEHAVIOR OF FIBER REINFORCED POLYMER (FRP) STRENGTHENED REINFORCED CONCRETE (RC) BEAMS CONTAINING LARGE RECTANGULAR WEB OPENINGS IN THE FLEXURE ZONE. STUDIED PARAMETERS WERE TYPE OF LOADING AND OPENING SIZE. ELEVEN RC BEAMS CATEGORIZED INTO TWO DIFFERENT GROUPS WERE ADOPTABLE IN FE MODEL SOFTWARE ... Read more
