Advanced Prestressed Concrete Part 6: Transverse Design of Double Tee Flanges-Advanced Precast, Prestressed Concrete Module 6: Video

Video Transcription

Video Summary

Summary:<br />The video covers the design and analysis of double-T beams, focusing on transverse design, openings in webs, and warping. It refers to the PCI Design Handbook for guidance. The transverse design of double-T flanges is discussed, including different methods like elastic plate solutions and effective slab width. Designing and detailing openings in webs is also explained, with recommendations on location and avoiding concentrated forces. The video mentions the PCI Design Handbook's guidance on geometric requirements and shear distribution. The second part of the video discusses calculating moment and shear at sections with openings, considering dimensions and loading conditions. The evaluation of warping in double-T beams is explained, including estimating torsional moment and its impact on cracking. The video provides detailed calculations and explanations for both topics. No credits were granted for the video content.
