DESCRIPTION:In 2022\, building operations and construction accounted for 3
 7% of total global energy and process related CO2 emissions (UNEP\, 2023).
  Reducing these emissions is urgent. It is therefore worth rethinking the 
 most used building material – concrete. \n\nOne approach to lowering the
  embodied carbon of concrete structures is shape optimisation – using ma
 terial only where it is needed and taking advantage of the fluidity of con
 crete to create non-prismatic structural elements (Orr 2012\; Orr et al. 2
 014). Another approach is replacing traditional steel reinforcement by alt
 ernative reinforcement\, such as WFRP (Wounded-Fibre-Reinforced-Polymer) B
 ars which show the potential to reduce the embodied carbon compared to the
 ir steel-reinforced counterparts (Pavlović et al. 2022\; Garg and Shrivas
 tava 2019\; Inman et al. 2017). \n\nHowever\, non-prismatic beams and slab
 s might be more prone to excessive deflection than their prismatic counter
 parts due to reduced flexural stiffness (Tayfur 2016). Additionally\, WFRP
 -reinforced elements often exhibit greater deflection than steel-reinforce
 d ones\, because FRP bars (except carbon FRP) typically have a lower elast
 ic modulus than steel.\n\nTo address this issue\, it is necessary to optim
 ise the shape of WFRP - reinforced structural elements for Serviceability 
 Limit State (SLS)\, ensuring they achieve lower embodied carbon than steel
 -reinforced ones whilst meeting design requirements for SLS. To achieve th
 is\, a theoretical method of shape optimisation for SLS is proposed\, demo
 nstrating higher efficiency than the existing method (Tayfur 2016). In add
 ition\, a flexural test on three BFRP (basalt FRP) reinforced concrete sla
 bs was conducted in the NFRIS (National Research Facility for Infrastructu
 re Sensing) laboratory in 2024.\n \nThis presentation will cover this expe
 rimental study on the deflection of non-prismatic slabs in flexure as well
  as the theoretical method of shape optimisation for SLS.
