  • Influence of an Acidic Environment on a Glass Fibre Reinforced Polymer Grid 

    Šimůnek, Petr; Štěpánek, Petr; Švaříčková, Ivana; Prokeš, Jan; Laníková, Ivana; Žítt, Petr; Miranda Mendes, Joo Pedro (EDP Sciences, 2020-03-05)
    The article deals with the influence of an acidic environment on the mechanical properties of a Glass Fibre Reinforced Polymer (GFRP) grid. The influence of an acidic environment is examined on samples cut from a GFRP grid. ...
  • Life Cycle Assessment Optimization of a Shotcrete Tunnel Lining 

    Štěpánek, Petr; Laníková, Ivana; Venclovský, Jakub (IOP Publishing, 2018-11-27)
    The proposed contribution describes the formulation of the optimization design of a utility tunnel lining. The objective function is defined as a multicriterial problem and includes economic and environmental aspects ...
  • Long-action of additional horizontal prestressing on masonry 

    Pěkník, Robin; Klusáček, Ladislav (Elsevier, 2017-07-20)
    This article is focused on verifying behaviour of a brick masonry which was horizontally post-tensioned. An experimental model of three walls has been built for the measurement. The model is in scale 1:1 and represents a ...
  • Probability-Based Design and Life Cycle Assessment of a Spun Concrete Pole 

    Štěpánek, Petr; Laníková, Ivana; Šimůnek, Petr (Atlantis Press, 2015-12-15)
    This contribution compares concrete structure design results obtained via the partial reliability factor method and using a probability-based method. The Monte Carlo simulation method, modified by the Latin Hypercube ...
  • Stochastic optimization of reinforced concrete elements’ design 

    Venclovský, Jakub; Štěpánek, Petr; Laníková, Ivana (IOP Publishing, 2018-07-04)
    Main goal of the paper is to present an algorithm for stochastic optimization of design of steel-reinforced concrete element’s cross section. Firstly, the deterministic problem is introduced and described, followed by the ...
  • Strengthening and Rehabilitation of U-Shaped RC Bridges Using Substitute Cable Ducts 

    Svoboda, Adam; Klusáček, Ladislav; Olšák, Martin (Hindawi Limited, 2019-11-30)
    The presented paper deals with strengthening and rehabilitation of U-shaped reinforced concrete bridges from the period of 1905–1930 using post-tensioning, which is a suitable, reliable, and durable method. These bridges ...
  • Strengthening of bridges by post-tensioning using monostrands in substituted cable ducts 

    Klusáček, Ladislav; Svoboda, Adam (IOP Publishing, 2017-09-15)
    Post-tensioning is suitable, reliable and durable method of strengthening existing engineering structures, especially bridges. The high efficiency of post-tensioning can be seen in many applications throughout the world. ...
  • Transverse prestressing and reinforced concrete as the key to restoration of masonry arch bridges 

    Klusáček, Ladislav; Nečas, Radim; Požár, Michal; Pěkník, Robin; Svoboda, Adam (Elsevier, 2021-08-07)
    There is still a large number of masonry arch bridges on the road and railway network. More than 80 % of arch bridges are over 100 years old so their service life has been exceeded significantly. The general focus of the ...
