    • COMPARISON OF METHODS USED FOR SEISMIC ANALYSIS OF STRUCTURES 

      Author: Čada, Petr; Máca, Jiří
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This paper investigates effects of the seismic load to a structure. The article describes main methods of the definition and practical application of the seismic load based on the Standard Eurocode 8. There was made a ...

    • PARALLEL APPROACH TO SOLVE OF THE DIRECT SOLUTION OF LARGE SPARSE SYSTEMS OF LINEAR EQUATIONS 

      Author: Bošanský, Michal; Patzák, Bořek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The paper deals with parallel approach for the numerical solution of large, sparse, non-symmetric systems of linear equations, that can be part of any finite element software. In this contribution, the differences between ...

    • USING HOMOGENIZATION AND NANOINDENTATION FOR MICROFIBRIL ANGLE DETERMINATION OF SPRUCE 

      Author: Kucíková, Lucie; Hrbek, Vladimír; Vorel, Jan; Šejnoha, Michal
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This paper is concerned with the evaluation of microfibril angle of spruce. The microfibril angle is defined as an inclination of microfibrils from the longitudinal axis, the direction of lumens. It is well known and further ...

    • DRYING CHARACTERISTIC OF RAMMED EARTH WITH ILLITIC-KAOLINITIC CLAY CONTENT 

      Author: Otcovská, Tereza; Mužíková, Barbora; Padevět, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Clay is a traditional construction material which has got to background with introduction of modern materials to building practice. There is no proper material available for clay constructions design due to lack of proper ...

    • EVALUATION OF MICROMECHANICAL PROPERTIES OF CARBON FIBER FABRIC USING NANOINDETATION 

      Author: Klapálek, Pavel; Prošek, Zdeněk; Jíra, Aleš; Melzerová, Lenka
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This paper is focused mainly on nanoindentation of carbon fibers. Fibers are in form of carbon fiber fabric that is used in larger research that is focused on reinforcing beams made of glued laminated timber. Knowledge of ...

    • GEOMETRICAL OPTIMIZATION OF DENTAL IMPLANTS WITH REGARD TO OSSEOINTEGRATION 

      Author: Řehounek, Luboš; Denk, František; Jíra, Aleš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      A newly developed reference dental implant specimen type was subjected to numerical simulations of osseointegration. The goal of these tests was to optimize the geometry of the implant so as to reduce local stress ...

    • WATER ABSORPTION CAPACITY COEFFICIENT AND MASS MOISTURE OF RAMMED EARTH MATERIAL 

      Author: Mužíková, Barbora; Otcovská, Tereza; Padevět, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This article presents the development of mass moisture of rammed earth material and determines the water absorption capacity coefficient for rammed earth with illite-kaoline clay. Specimens of two prescriptions were rammed ...

    • LONG-TIME INVESTIGATION OF CEMENT COMPOSITE MATERIAL WITH MICRONIZED WASTE MARBLE POWDER: DYNAMIC MODULES 

      Author: Prošek, Zdeněk; Topič, Jaroslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This article focus on “blended cement”. The blended cement was created by using waste marble powder (WMP) as a partial replacement for cement. We investigated the influence of WMP on the developing of the dynamic modulus ...

    • SOLID BURNT BRICKS’ TENSILE STRENGTH 

      Author: Maroušková, Aneta; Kubát, Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This paper deals with experimental testing of solid burnt bricks and mortar in pure (axial) tension. The obtained working diagrams will be further use for a detailed numerical analysis of whole brick masonry column under ...

    • WANG TILE SIZE IN TERMS OF CIRCULAR PARTICLE DYNAMICS 

      Author: Šedlbauer, David
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The main advantage of the Wang tiling concept for material engineering is ability to create large material domains with a relatively small set of tiles. Such idea allows both a reduction of computational demands and ...

    • ADAPTIVE QUASICONTINUUM SIMULATION OF ELASTIC-BRITTLE DISORDERED LATTICES
