Through a nuanced analysis, the research uncovers the intricate relationships between waste management practices and the broader urban fabric. The analysis of social impacts reveals that waste sorting not only induces individual behavioral changes but also fosters community engagement, social cohesion, and a shared sense of responsibility. Sustainable development outcomes encompass environmental benefits, social gains, and economic opportunities generated by the evolving waste management sector. Identified challenges, including cultural resistance and infrastructure limitations, serve as opportunities for targeted interventions and improvements to enhance the inclusivity and efficacy of waste sorting practices. Recommendations encompass strengthening public education, embracing technological solutions, fostering community involvement, tailoring initiatives to cultural values, investing in infrastructure, and introducing incentive programs.","PeriodicalId":511174,"journal":{"name":"Innovation in Science and Technology","volume":"39 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139639425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The specimens were modelled in geometry, material, constraints, load and boundary conditions using ABAQUS package and dynamic explicit analysis was used to investigate the crack pattern, failure mode and stress-stain behaviour of the UHPFRC specimens when subjected to uniaxial compression and tension loading. Results from the FE simulation revealed that the surfaces of the UHPFRC specimens were still in good shape after attaining their ultimate resistance against compression and tension loading. The UHPFRC’s ultimate compressive strength of 260N/mm2 was just 7% higher than the experimental compressive strength. The UHPFRC exhibited both linear compressive stress-strain behaviour up to 89% of its peak strength and non-linear stress-strain behaviour with strain hardening and strain softening phases. Further findings also showed that the UHPFRC despite having ultra-high tensile strength did not undergo strain hardening phase as the vertical direction stresses were mainly distributed around the loaded section of the specimen. The FE UHPFRC models’ strength in compression and tension only has slight and negligible variations from the experimental strengths. The deformation and strength performance of the FE specimens are in perfect agreement with the experimental specimens. Therefore, FE modelling and simulation can be used as a reliable method of carrying out extensive studies on UHPFRC properties and performances.","PeriodicalId":511174,"journal":{"name":"Innovation in Science and Technology","volume":"68 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139635315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
