predicting embodied carbon and cost effectiveness of post-tensioned slabs using novel hybrid firefly ann
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.

applications of sustainable post-tensioned concrete slabs - innovative infrastructure solutions
post-tensioning is used for the last decades for different concrete elements such as slabs, beams, walls and mat foundations. for industrial and office buildings with large spans, application of post-tensioned, (pt), concrete floors is competitive to reinforced concrete. use of pt slabs results in small sections, better serviceability, durable structures and faster construction compared to reinforced concrete construction. in some cases, it demonstrates an economic alternative to conventional concrete or steel floors. post-tensioning concrete slabs are applied using either bonded or unbonded tendons. bonded tendons is achieved by grouting the ducts containing the steel tendons after stressing. consequently, the prestressing force is transmitted to the concrete by bond along the steel tendons. in unbonded tendons applications, the ducts are left after stressing without grouting and the force is transmitted at the anchorages of the prestressing steel. this paper introduces analysis, design and construction techniques of pt concrete floors. computer model specifically made to design pt slabs satisfying the requirements of the code is introduced. case studies carried out in egypt and in the gulf area in the last few years with particular application of post-tensioning are also introduced. these case studies include buildings of spans up to 24.0 ms, as well as water tank of 100,000 m3 capacity. recommendations and design guidelines of pt concrete slabs as well as the assessment of the current egyptian code are highlighted.
