    • Comparison of behaviour of burnt beams models with effective and actual residual cross-sections in three point bending test 

      Autor: Keřková Kucíková, Lucie; Šejnoha, Michal; Janda, Tomáš; Padevět, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      Glued laminated timber beams exposed to fire of a variable duration were tested in three point bending. Three types of model geometries taking into account the effect of burning were created. Each model was examined for ...

    • CORRELATION RELATIONSHIPS FOR THE HYPOPLASTIC MODEL FOR FINE GRAINED SOILS 

      Autor: Kadlíček, Tomáš; Janda, Tomáš; Šejnoha, Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The paper is concerned with our ongoing research effort devoted to the development of reliable computational tools for the calibration of advanced constitutive models of soils. At present, such software is available for ...

    • EVALUATION OF IMPACT OF ELEVATED TEMPERATURES ON YOUNG’S MODULUS OF GLT BEAMS 

      Autor: Kucíková, Lucie; Šejnoha, Michal; Janda, Tomáš; Padevět, Pavel; Marseglia, Guido
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The influence of elevated temperatures on mechanical behavior of glued laminated timber beams is examined on the basis of tensile tests. Dog bone samples prepared from beams exposed to fire of variable duration were ...

    • Extracting general knowledge of model parameters for clays out of numerous laboratory tests 

      Autor: Pavelcová, Veronika; Janda, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      This paper is concerned with the process of determining the material parameters of advanced constitutive models for clays. Provided results are applicable already in the early stages of geotechnical survey when no detailed ...

    • INFLUENCE OF MATERIAL DAMPING ON THE RESPONSE OF UNDERGROUND STRUCTURES SUBJECTED TO EARTHQUAKE 

      Autor: Pavelcová, Veronika; Poklopová, Tereza; Šejnoha, Michal; Janda, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      The paper describes a finite element simulation of the response of a real underground structure subjected to earthquake using GEO5 FEM program. It concentrates on the influence of material damping with respect to a specific ...

    • MODELING OF UNDERGROUND STRUCTURES SUBJECTED TO EARTHQUAKE BY COMBINING 1D FREE-FIELD AND 2D PSEUDO-STATIC ANALYSES 

      Autor: Poklopová, Tereza; Pavelcová, Veronika; Janda, Tomáš; Šejnoha, Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
      The paper deals with the evaluation of tunnel construction subjected to earthquake using a pseudostatic analysis combined with the finite element method. The initial stage of calculation is concerned with the design of ...

    • Newmark algorithm for dynamic analysis with Maxwell chain model 

      Autor: Schmidt , Jaroslav; Janda , Tomáš; Zemanová , Alena; Zeman , Jan; Šejnoha , Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
      This paper investigates a time-stepping procedure of the Newmark type for dynamic analyses of viscoelastic structures characterized by a generalized Maxwell model. We depart from a scheme developed for a three-parameter ...

    • Phase-field damage of laminated glass in explicit dynamics 

      Autor: Schmidt, Jaroslav; Janda, Tomáš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
