The Hybrid Effect Of Introducing Metallic And Nonmetallic Fibers Into Concrete At A Full-Scale Beam-Column Joint Section Under Seismic Load Is Investigated In This Thesis. The Study Intends To Assess The Changes In Mechanical Characteristics And General Performance Of The Beam-Column Joints Attained By Means Of Hybrid Fibers. Four Different Hybrid Fiber Combinations—Hooked End Steel Fiber With Basalt Fiber And Crimped Steel Fiber With Polypropylene Fiber—Were Used In Conjunction With One Normal Grade Concrete Mix (M25). Designed And Tested In A Lab, These Combinations Were Meant To Have Compressive, Tensile, And Flexural Strengths According To Pertinent Indian Standard Code Requirements. Designed Following Bureau Of Indian Standards (BIS), The Full-Scale Beam-Column Joint Section Included Ductile Detailing In Line With Seismic Design Criteria. The Finite Element Program ANSYS V21 Modeled The Same Geometric Arrangement. Based On Experimental Data, Mathematical Representations Of Concrete And Steel Have Been Established Including Non-Linear Stress And Strain Relationships In Uniaxial Tension And Compression. Two Loading Conditions Were Applied To The Finite Element Models: Non-Linear Reverse Cyclic Displacement-Controlled Loading, Simulating Seismic Effects; Steady Static Loading. Important Performance Criteria Including Initial Crack Load, Initial Crack Deflection, Ultimate Load Capacity, And Ultimate Deflection Were Assessed In This Work. In Terms Of Compressive Strength, Flexural Strength, Energy Dissipation Capacity, And Stiffness Degradation The Hybrid Combination Of 0.40% Basalt Fiber With 0.80% Hooked End Steel Fiber Outperformed The Other Mixtures. Probably Because Of The Microfilament Character Of The Polypropylene Fibers, The Hybrid Effect Of 0.80% Crimped Steel And 0.20% Polypropylene Fiber Displayed The Highest Tensile Strength And Best Resistance To Initial Cracking. But Raising The Polypropylene Content To 0.40% Caused Both Tensile And Flexural Strengths To Gradually Drop. Iv. The Results Of This Study Advance Knowledge Of The Combined Effects Of Hybrid Fiber Reinforcement In Concrete, Especially For Important Structural Elements Like Beam-Column Joints Under Seismic Load. By Means Of Hybrid Fiber Reinforcement, The Enhanced Mechanical Qualities And Enhanced Crack Control Can Perhaps Result In Stronger And Durable Buildings, So Reducing The Risk Of Serious Damage During Seismic Events.
