post-tensioning has become a strong contender for manufacturing reinforced concrete (rc) members, especially for flat slabs in large-span structures. post-tensioned (pt) slabs can lead to considerable material savings while reducing the embodied carbon (embodied co2), construction time, and life cycle maintenance and repair costs. in this research, a novel hybrid firefly–artificial neural network (firefly–ann) computational intelligence model was developed to estimate the cost effectiveness and embodied co2 of pt slabs with different design variables. to develop the dataset, several numerical models with various design variables, including the pattern of tendons, slab thickness, mechanical properties of materials, and span of slabs, were developed to investigate the sustainability and economic competitiveness of the derived designs compared to benchmark conventional rc flat slabs. several performance measures, including punching shear and heel drop vibration induced by human activity, were used as design constraints to satisfy safety and serviceability criteria. the economic competitiveness of pt slabs was more evident in larger spans where the cost and embodied co2 emissions decreased by 39% and 12%, respectively, in pt slabs with a 12-m span length compared to conventional rc slabs. sensitivity analysis also confirmed that the cost and embodied co2 emissions were very sensitive to the slab thickness by 86% and 62%, respectively.
answer (1 of 4): post-tensioned slabs contain a tendon, or steel cable, that runs crisscrossed throughout the center of the slab after the concrete has already hardened. as the poured concrete dries, the post-tensioned cables stretch and tighten, which applies a significant force to the concrete ...

we recently had a 5,696 square foot post tension slab poured here in north texas on 2/14/2014. as of today, march 3 no one has come back out to stress the tendons in our slab. today i noticed, what i (the homeowner) consider, severe cracking in the slab. now i understand that there is some cracking that can happen due to shrinkage and the fact that the pt cables are unbonded to concrete. i accepted that. but what i am witnessing today is very long cracks (some over 50’ in length) that go ac...

several researchers have studied how impact loads from impact hazards affect reinforced concrete (rc) slabs. there is relatively little research on impact loading effects on pre-stressed structures. the usage of fibers in structural elements intrigued researchers. in this paper, impact-loaded post-tensioned (pt) slabs with and without forta-ferro fibers were compared to post-tensioned slabs with plain concrete and conventional shear reinforcement. forta-ferro is a lightweight, low-cost fiber, and hence its effects on slab structural response under impact load deserve to be explored. post-tensioned slabs’ impact resistance and energy absorption were tested using real-world situations of rapid and severe loads. four identical 3.3 by 1.5 m concrete slabs were utilized in the experiment. the experiment involved dropping a 600 kg iron ball from 8 m onto each slab’s center of gravity. the slabs’ responses were investigated. the four slab configurations were tested for displacement, energy absorption, and cracking. forta-ferro fiber reinforcement is understudied, making this study significant. the study’s findings may help us comprehend fiber-reinforced concrete pt slabs’ impact resistance and structural performance. engineers and designers of impact-prone buildings like slabs and bridges will benefit from the findings. the study also suggests adding forta-ferro fibers to post-tensioned slabs to improve durability and resilience against unanticipated impact hazards.
