    • Service life prediction’s algorithm: loading, carbonization, chloride aggression 

      Shalyi, Evgeny Evgenievich; Leonovich, Sergej Nikolaevich; Budrevich, Nelly Anatolyevna (BrSTU, 2021)
      Corrosion reinforcement marine hydraulic structures due to chloride aggression and carbonization of concrete leads to a sharp decrease in the safety of the structure. The steel reinforcement will be subjected to a so-called depassivation process, once the chloride concentration on surface exceeds a ...

    • Robustness assessment of precast reinforced concrete structural systems in an accidental design situation 

      Tur, Victor Vladimirovich; Tur, Andrey Viktorovich; Lizahub, Aleksandr Aleksandrovich (BrSTU, 2021)
      The article presents the simplified implementation of the method of alternative load paths based on the energy balance approach. This method should be used to checking the global resistance of a damaged structural system after the occurrence of an accidental event. It is necessary to provide (reserve) ...

    • Some remarks about chemical prestressing of FRP reinforce-ment 

      Tur, Victor Vladimirovich (BrSTU, 2021)
      In last years has been observed a new wave of interest in the research and practical use of self-stressing concrete, now in combination with various types of non-traditional reinforcement. One of the widely used types of these reinforcements is FRP bars and long fibers (textile). We connect the major ...

    • Estimation of the shear resistance models of reinforced concrete elements without stirrups according to various design codes 

      Tur, Victor Vladimirovich; Varabei, Alexander Petrovich; Derechennik, Stanislav Stanislavovich (BrSTU, 2021)
      This paper presents the results of assessments shear design models with experimental data, included in the current and developed standards for the design of reinforced concrete structures.

    • Fracture toughness of carbon nanotubes modified cement based materials 

      Zhdanok, Sergey Aleksandrovich; Polonina, Elena Nikolaevna; Sadovskaya, Elena Alexandrovna; Leonovich, Sergej Nikolaevich (BrSTU, 2021)
      In order to increase the fracture toughness of concrete, dispersed fiber reinforcement is increasingly used in practice. The initiation of crack initiation occurs at the nanoscale in the cement matrix. Thus, the use of nano-reinforcement with dispersed nanoparticles can have a positive effect on the ...
