Stress Calculation for Parabolic Tendons in Prestressed Concrete || Strength Concept Method

Advanced Analysis of PSC | Load Balancing (Parabolic) & Strength Concept ​Welcome back to CIVIL GYAN CENTER! In this comprehensive session, we move beyond the basics to master the advanced analytical methods used in Prestressed Concrete (PSC). Understanding how the internal "C-line" shifts and how parabolic tendons balance distributed loads is key to cracking high-level competitive exams. ​📝 Key Topics Covered in This Video: ​Load Balancing Method (Parabolic Tendons): How a parabolic profile exerts a uniform upward pressure (w_p = \frac{8Pe}{L^2}) to counteract UDL. ​Effect of Loading: Analyzing stress variations from the "Prestress only" stage to the "Full Working Load" stage. ​Strength Concept (Internal Resisting Couple): Viewing PSC as a concrete-steel couple where the lever arm changes with external moments. ​C-Line and P-Line: Understanding the "Pressure Line" (C-line) vs. the "Tendon Profile" (P-line) and how their divergence represents the external moment. ​Cracking Moment Calculation: Determining the exact moment at which the bottom fiber stress reaches the modulus of rupture (f_{cr}). ​💡 Why This is Critical for ESE & GATE: ​Questions on the C-line shift and Equivalent UDL from parabolic tendons are frequently asked in technical interviews and conventional papers. We break down these "tough" concepts into simple, visual steps to ensure you never get confused between the Stress Concept and the Strength Concept again! ​🚀 Target Exams: ​​​​​​✅ ESE (Engineering Services Examination) ✅ SSC JE (Civil) ✅ RRB JE ✅ UPPSC Polytechnic Lecturer ✅ State AE/JE Exams ✅ GATE Civil Engineering ​🚀 About CIVIL GYAN CENTER: ​​​​​​We provide simplified, conceptual, and exam-oriented content for Civil Engineering aspirants.
