چکیده مقاله
Considering the importance of moment frames in concrete structures, reinforcing them withhigh performance fibers is very effective High performance fiber reinforced cementitiouscomposite HPFRCC materials exhibit strain hardening behavior under tension and can beused in seismic rehabilitation of structural members The aim of this research is to evaluate theseismic performance of reinforced concrete and compare them with reinforced concrete frames,which was carried out using the numerical analysis method and ABAQUS finite elementsoftware to model a moment frame under different loads After validating the softwareperformance, the modeling of the conventional reinforced concrete frame was conducted Then,its panel zone was replaced by HPFRCC materials with different resistances and differentpercentages of reinforcements, and it was compared with reinforced concrete frame andreinforced HPFRCC frame The results showed that with the increase of the vertical force onthe frame, the yield corresponding lateral displacement in reinforced concrete, reinforcedcomposite HPFRCC and HPFRCC frames decreased 13 41%, 24 41% and 17 34%,respectively Lateral bearing capacity in reinforced concrete, reinforced composite HPFRCCand HPFRCC frames decreased 1 2%, 1 4% and 2 7%, respectively In HPFRCC frames, byincreasing the size of rebars from 12 to 14 mm and 16 mm, the force increased by 5% and 20%,respectively, and the lateral displacement decreased by 3% and 4 5%, respectively Byincreasing the reinforcement area in the frame columns of all frames, the plastic hinge length lP and the plastic hinge rotation θP decreased in the columns and increased in the beam
