Webinar: Restraint Cracks and their Mitigation in Unbonded Post-tensioned Building Structures

Video Transcription

Video Summary

The video transcript covers a webinar on restraint cracks in post-tensioned structures led by Seat Baxi. The presentation discusses the importance of considering restraint in post-tensioned buildings, methods to mitigate restraint cracks, computation of shortening, and the use of slip details, crack control reinforcement, and layout of tendons to prevent cracking. Various examples and methods are presented, including the ACI 209 method, PCI method, and simplified method for calculating shortening. Practical tips and recommendations are provided, such as coordinating slip details with contractors, using materials to minimize friction, and participating in technical institutes for career growth. The webinar concludes with upcoming topics and contact information for further inquiries.
