  2. 1. FUNCTIONAL PRODUCTS: HIGHLIGHTING THE POTENTIAL AND EXTENDING THE DEFINITION

    Author : Daria Sas; Erik Sundin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : The Functional Product (FP) concept has brought an innovative view on howproducts can be offered to customers. When offering FP, the FP provider iscommonly responsible for the hardware performance, which may be basedeither on an existing product or on a new product. READ MORE

  5. 3. FRP shear strengthening of RC beams and walls

    Author : Gabriel Sas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The shear failure of Fibre Reinforced Polymers (FRP) strengthened reinforced concrete (RC) beams has not been studied to the same extent as the bending failure mechanism in the past decade. The complex nature of the shear failure mechanism just for reinforced concrete beams is still under debate among scientists and not solved yet. READ MORE

  6. 4. FRP shear strengthening of reinforced concrete beams

    Author : Gabriel Sas; Giorgio Monti; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber reinforced polymers; shear; reinforced concrete; strengthening; model; comparison; literature review; Structural Engineering; Konstruktionsteknik;

    Abstract : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

  7. 5. Characterization of train-induced aerodynamic loads on high-speed railway vertical noise barriers

    Author : Dongyun Liu; Gabriel Sas; Chao Wang; Jaime Gonzalez; Lennart Elfgren; Yongming Tu; Paolo Zampieri; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerodynamic pressure; Computational fluid dynamics; Train geometry; High-speed railway; High-speed train; Load calculation model; Vertical noise barrier; Byggkonstruktion; Structural Engineering;

    Abstract : High-Speed Railway (HSR) technology requires the deployment of noise barriers to mitigate noise pollution affecting nearby residents. As train speeds increase, so does the magnitude of aerodynamic effects such as aerodynamic noise and the pressure on these barriers, meaning that these structures require robust sound insulation and structural load-bearing capacities.
