Learn to analyze prestressed concrete (PSC) beams subjected to torsional forces after cracking has occurred in this 20-minute lecture from NPTEL-NOC IITM. Examine the behavior and structural response of cracked prestressed concrete sections under torsional loading conditions. Understand the analytical methods and procedures required to evaluate the performance of PSC beams once the concrete has cracked, focusing on the redistribution of stresses and the role of prestressing tendons in maintaining structural integrity. Explore the theoretical framework for analyzing cracked sections and gain insights into the post-cracking torsional behavior that is essential for advanced concrete design and structural analysis.
