    • Reliability of a structure stricken by a tornado 

      Autor: Holický, Milan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      A tornado may become a very dangerous climatic action for any structure, depending on the tornado intensity and extent of the structure. The origin of a tornado, its range and further activity appear to be unpredictable ...

    • Reliability of existing reinforced concrete slabs exposed to punching shear 

      Autor: Marková, Jana; Holický, Milan; Jung, Karel; Sýkora, Miroslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      Selected standardised models for the verification of punching shear in reinforced concrete structures are applied for the probabilistic assessment of their reliability level. It appears that the models given in EN 1992-1-1 ...

    • Risk based maintenance for Swiss railway bridges: concept, implementation and first experiences 

      Autor: Proske, Dirk; Payeur, Jean-Baptiste; Girardin, Blaise; Friedl, Herbert
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The Swiss Federal Railway (SBB) has an inventory of approx. 6,000 bridges. So far, condition classes of the individual bridges have been used for maintenance management. To improve the efficiency of the maintenance management, ...

    • Semi-probabilistic assessment of existing bridge using simplified methods for estimation of variance 

      Autor: Novák, Lukáš; Novák, Drahomír
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The paper is focused on assessment of existing prestressed concrete bridge by simplified methods for estimation of coefficient of variation. The bridge was selected in the framework of the European Project INTERREG ...

    • Simplified modelling of the performance of concrete tunnels during fire and post-fire damage classification 

      Autor: Van Coile, Ruben; Jovanović, Balša; Chaudhary, Ranjit Kumar; Deckers, Xavier; Lucherini, Andrea
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The performance of concrete tunnel structures during and after fire is not well understood. This is an obstacle to the adoption of risk-based approaches for fire safety design of tunnel structures. Upon the request of the ...

    • Statistical characterisation of reinforcement properties for textile-reinforced concrete: a novel approach 

      Autor: Ricker, Marcus; Rempel, Sergej; Feiri, Tânia; Schulze-Ardey, Jan; Hegger, Josef
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      The potential of textile-reinforced concrete is broad: it can be used in new structures and in the retrofitting of existing structural components. Designing textile-reinforced concrete requires knowledge about the mechanical ...

    • Structural assessment and expected utility gain 

      Autor: Thöns, Sebastian
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      This paper contains an introduction, probabilistic formulation, and exemplification (1) of system state and utility actions, (2) system state and utility action value analysis and (3) a threshold formulation for a predicted ...

    • Structural reliability of existing rc beams strengthened with UHPFRC tensile layers 

      Autor: Simwanda, Lenganji; De Koker, Nico; Viljoen, Celeste; Babafemi, Adewumi John
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      A methodology for reliability analysis of reinforced concrete (RC) beams strengthened with ultra high-performance fibre reinforced concrete (UHPFRC) tensile layers is presented. The proposed methodology includes stochastic ...

    • Structural reliability of hollow core slabs considering compressive membrane action 

      Autor: Thienpont, Thomas; Van Coile, Ruben; De Corte, Wouter; Caspeele, Robby
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      Compressive membrane action can considerably improve the load bearing capacity of concrete slabs and beams in case of excessive loaded due to an accidental event. Currently, only limited research has been focusing on ...

    • The role of multi-fidelity modelling in adaptation and recovery of engineering systems 

      Autor: Teixeira, Rui; Martinez-Pastor, Beatriz; Nogal, Maria; Micu, Alexandra; O’Connor, Alan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      Significant research has been conducted in identifying optimal recovery and adaptation decisions in disruptive scenarios using engineering models. In this context, an aspect that has been target of limited research is that ...

    • Uncertainty assessment for the Bayesian updating process of concrete strength properties 

      Autor: Haslbeck, Matthias; Kroyer, Robert; Taras, Andreas; Braml, Thomas
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
      Reassessment of infrastructure buildings has become an essential approach to deal with increasing traffic loads on ageing infrastructure buildings and to verify the service-life of those structures. Good estimation of the ...
