Cost-optimal design of flexural concrete beam reinforced with FRP reinforcements
Tveit, Sigbjørn; Wilhelmsen, Martin; Lundeland, Vlad Aleksander; Kioumarsi, Mahdi (SynerCrete'18: Interdisciplinary Approaches for Cement-based Materials and Structural Concrete: Synergizing Expertise and Bridging Scales of Space and Time.;Vol. 1&2, Chapter; Chapter; Peer reviewed, 2018-10-22)Because of the non-ductile nature of FRP reinforcement, the convention of designing cross-sections with the flexure strength limited by reinforcement yield, as for steel, is not adequate. Although ACI 440.1R-15 gives ... -
Fiber reinforced polymer (FRP) som slakkarmering i momentpåkjente betongkonstruksjoner.
Wilhelmsen, Martin; Lundeland, Vlad Aleksander; Tveit, Sigbjørn (Bachelor thesis, 2018)Denne bacheloroppgaven omhandler bruken av ikke-metallisk slakkarmering i momentpåkjente konstruksjonselementer av betong. Formålet var å danne et bilde av armeringens virkning i betongkonstruksjoner. Oppgaven omhandler ... -
Formability analysis of AA6016-T4 aluminium alloy sheets subjected to roping
Tveit, Sigbjørn (MABY;2020, Master thesis, 2020)Due to its good formability characteristics, AA6xxx aluminium alloys have become popular as a light-weight alternative to steel for components produced by stamping operations for use in the bodywork of cars. In this thesis, ... -
Formability of AA5083-H111 aluminum sheets for use in floating photovoltaic structures
Jibrail, Jon (Master thesis, 2023)This investigation focuses on formability aspects of aluminum alloy AA5083-H111 to improve the forming process for floating photovoltaic structures. The study targets the identification of limiting variables and efficiency ... -
