Michael Hopper has co-authored "Assessment of the embodied carbon performance of post-tensioned voided concrete plates as a sustainable floor solution in multi-story buildings" with Jonathan M. Broylesab published in Engineering Structures, Volume 295, 15 November 2023, 116847
LERA Consulting Structural Engineers (LERA) has designed and constructed PT voided plates over the last decade... These buildings have successfully used PT voided plates to simplify formwork and minimize concrete and steel reinforcing quantities.
Highlights
Six concrete floor systems are assessed and compared for EC savings.
PT voided plates have an EC savings up to 51% compared to conventional RC plates.
Concrete material quantities in the floor slab can be reduced up to 56%.
Non-traditional tendon layouts require fewer tendons compared to orthogonal layouts.
PT voided plates have comparable EC savings to alternative floor solutions.

This is a really insightful study! It’s great to see how PT voided plates are not only improving structural efficiency but also contributing to significant reductions in embodied carbon. The 51% savings compared to traditional RC plates is impressive! It’s exciting to think about how these innovations can play a role in more sustainable construction practices moving forward.
