Hollow Core Diaphragm Design-Hollow Core Diaphragm Design

Video Transcription

Video Summary

Summary:<br /><br />The first video discusses holocore diaphragm design, covering topics such as design criteria, the difference between rigid and flexible diaphragms, determining diaphragm type, requirements for thickness, reinforcement, and detailing, seismic load path, cast-in-place composite topping, shear strength and reinforcement, flexural strength, and upcoming ACI 716 methodologies for design.<br /><br />The second video focuses on design and detailing considerations for hollow core diaphragms in wind and seismic conditions. It covers shear friction reinforcement, boundary elements, cords, collectors, joints, composite and untopped diaphragms, design example with calculations for lateral forces and reinforcement, differences between wind and seismic design, seismic design categories, following ACI 318 and ASCE 7 codes, and utilizing the PCI hollow core manual.<br /><br />No credits were mentioned in either video.
