Basic Prestressed Concrete Design Part 6: Quantities and Allowable Values-Basic Prestressed Concrete Design

Video Transcription

Video Summary

The video is a summary of the last session of a course on designing rectangular beams, specifically focusing on shear strength and shear design of pre-stressed concrete beams. The speaker discusses the provisions for shear design in reinforced and pre-stressed concrete members, explaining the equations used to determine shear strength. They also discuss potential failure modes and how to calculate the contributions of concrete and steel to shear strength.<br /><br />The video covers determining the live load pattern to generate maximum shear along the span of a beam using Influence Lines. The speaker explains how to calculate the maximum moment along the beam and how to calculate BCI and BCW for shear design.<br /><br />A step-by-step process for shear design is provided, including creating the vis-a-vis diagram, extrapolating VI and M max at the critical section, and calculating BCI and BCW for each combination of VI and M max. The video also explains how to calculate the reduced nominal strength and determine if shear reinforcement is required.<br /><br />The video concludes by thanking Sherry for assisting with the course and expressing gratitude to all the participants. The speaker hopes that the course was helpful and informative, wishing everyone a great evening.<br /><br />No specific credits are mentioned in the summary.
